See Figure 1. Solvent Platform Detector Autosampler Analytical Pump Figure 1. Thermo Electron Corporation Surveyor Plus LC instrument Surveyor Plus Getting Started with Xcalibur 1 1 Introduction to the Surveyor Plus Integrated LC/MS System Two analytical pumps are available: the Surveyor LC Pump Plus and the Surveyor MS Pump Plus. Each pump is a dual-piston, quaternary, low-pressure mixing solvent delivery system with a built-in vacuum degasser and pulse dampener. The LC pump operates in the flow rate range from 1 to 9999 μL/min. It provides precise gradients over a flow rate range of 200 to 2000 μL/min. The MS pump operates in the flow rate range from 1 to 2000 μL/min. It provides precise gradients in the flow rate range from 25 to 800 μL/min. Two autosamplers are available: the Surveyor Autosampler Plus and the Surveyor Autosampler Plus Lite. Both autosamplers automate sample injections and sample preparation. Their tray compartments accept various vials, 96-well plates, and 384-well plates. In addition to these features, the full-featured Surveyor Autosampler Plus includes a built-in column oven (5 to 95 °C) and sample compartment temperature control (0 to 60 °C). Two detectors are available: the Surveyor PDA Plus Detector and the Surveyor UV/Vis Plus Detector. The Surveyor PDA Plus Detector, in combination with the 5 cm LightPipe flowcell, provides the highest level of sensitivity available in photodiode array detection for HPLC. The Surveyor UV/Vis Plus Detector is a dual-wavelength UV/Vis detector. Both detectors have dual-lamp optical bench that covers the UV-visible spectrum from 190 to 800 nm. The solvent platform, which is located on the top of the Surveyor Plus LC stack, holds four 1-L solvent reservoir bottles and one 1-L wash bottle. Four 1/8-in. OD, 1/16-in. ID, FEP solvent lines carry solvent from the reservoir bottles down to the vacuum membrane degasser, which is built into the analytical pump. One 1/8-in. OD, 1/16-in. ID, FEP solvent line carries solvent from the wash bottle to the 2-position syringe valve of the autosampler. This chapter provides a brief description of the Surveyor Plus LC system and contains the following sections: • Analytical Pump • Surveyor Autosampler Plus • Surveyor PDA Plus Detector • Surveyor UV/Vis Plus Detector • Communication with Xcalibur • Synchronizing the Surveyor LC Devices • Status LEDs 2 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Analytical Pump Introduction to the Surveyor Plus Integrated LC/MS System Analytical Pump Thermo Electron offers two analytical pumps in the Surveyor Plus series: the Surveyor MS Pump Plus, which provides optimum performance in the lower flow rate ranges needed for mass spectrometry and the Surveyor LC Pump Plus, which provides optimum performance in the flow rate ranges needed for chromatography. Both analytical pumps contain a built-in solvent degassing system that consists of four independent chambers maintained at a constant vacuum of approximately 27-in. Hg. Each chamber contains an 18-in. length of 0.045-in. ID Teflon® AF tubing. This translates to a volume of less than 500 μL per channel, adding very little to the quantity of solvent that is required to purge the lines when you replace an eluent. The distinguishing features of these analytical pumps are described in the following topics contained in this section: • Surveyor MS Pump Plus • Surveyor LC Pump Plus Surveyor MS Pump Plus The Surveyor MS Pump Plus is a dual-piston, quaternary, low-pressure mixing pump with a built-in vacuum degasser and pulse dampener. The pumping system provides flow rates from 0.1 to 2000 μL/min, the range needed to perform LC/MS applications. You can run precise gradients from 25 to 800 μL/min. The built-in pulse dampening assembly consists of a low volume T-connector through which the mobile phase passes. Attached to the side leg of the T-connector is a permeable isolation membrane made of sintered Teflon followed by a 2 mL coil of stainless steel tubing. The coil is terminated with a priming valve. When the priming valve is open, the dampening coil can be flushed or filled with an appropriate solvent such as methanol or isopropanol. When the priming valve is closed, the diffusion barrier cartridge is shut off from the flow path and the dampening coil absorbs pump pulsations. Even at elevated pressures, the pump will show only minimal pulsation when the pulse dampener is used. Because the 2 mL coil is shut off from the flow path, the low volume T-connector of the pulse dampener adds only 3 μL of delay volume to your system. The Surveyor MS Pump Plus is remotely controlled by way of an RS232 serial communication link from a PC using Xcalibur software (version 1.3 or higher). The only manual control is the power switch located on the front of the pump in the lower left corner below the door. See Figure 2. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 3 1 Introduction to the Surveyor Plus Integrated LC/MS System Analytical Pump Power Switch Figure 2. Vacuum Degasser Liquid Displacement Assembly Pulse Dampener Front view of Surveyor MS Pump Plus Surveyor LC Pump Plus The Surveyor LC Pump Plus is a dual-piston, quaternary, low-pressure mixing pump with a built-in vacuum degasser and pulse dampener. The pumping system provides flow rates from 0.001 to 9.999 mL/min, the range that is needed to perform high performance liquid chromatography. You can run precise gradients from 0.200 to 2.000 mL/min. The Surveyor LC Pump Plus is a bench-top unit for inclusion in the Surveyor Plus high performance liquid chromatograph (HPLC). It is remotely controlled by way of an Ethernet communication link from a PC using Xcalibur (version 2.0 or higher). The only manual control is the power switch located on the front of the pump in the lower left corner below the door. Direct control of the pump is achieved through the Xcalibur data system. 4 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Introduction to the Surveyor Plus Integrated LC/MS System Analytical Pump The Surveyor LC Pump Plus, shown in Figure 3, has five major components: the vacuum degassing assembly; the solvent proportioning assembly; the pump head assemblies; the purge manifold assembly; and the pulse dampening assembly, which adds 400 μL of gradient delay volume to the system. In addition, the LC pump has status LEDs on the front door, and a low voltage power supply. Note Do not overtighten the fingertight fitting that connects the LC pump to the autosampler. See Figure 3. Overtightening this fitting will cause leaking.

You open the purge valve by turning the knob on the front of the purge manifold assembly counter-clockwise. See Figure 4. Open Position LO SE PE N C Figure 4. DRAIN O PE N DRAIN O SE LO C Closed Position Drain valve positions Figure 5 shows the line body fitting, located at the top of the purge manifold assembly. The line body fitting contains an in-line filter frit that captures particulate matter shed by the pump seals. This prevents particulate matter from contaminating the tubing that connects the pump to the autosampler. As this frit becomes clogged, your system backpressure rises. Replace this frit when your system backpressure rises above its typical operating limits. Figure 5. 6 Surveyor Plus Getting Started with Xcalibur Line body and filter frit Thermo Electron Corporation 1 Surveyor Autosampler Plus Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus The Surveyor Autosampler Plus allows you to inject samples and perform sample dilutions automatically. Thermo Electron offers two Surveyor Plus autosampler models: the full-featured Surveyor Autosampler Plus and the Surveyor Autosampler Plus Lite. The full-featured autosampler includes a built-in column oven (5 to 95 °C) and tray/sample temperature control (0 to 60 °C). The autosampler tray compartment, the injection system, the injection modes, and the temperature control features are described in the following topics: • Tray Compartment • Injection System • Injection Modes • Temperature Control Tray Compartment The tray compartment can hold up to five conventional sample trays or one microwell carrier. The tray compartment also holds up to four 12 mL capacity reservoir vials that can be used to hold solvent, reagent, or diluent. The reservoir vials are located behind the wash station and are designated RV1, RV2, RV3, and RV4. See Figure 6. XYZ Arm Mechanism RV4 RV3 RV2 RV1 Figure 6. Thermo Electron Corporation Wash Station Injection Port Tray compartment, showing brackets for needle tubing assembly Surveyor Plus Getting Started with Xcalibur 7 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus The five conventional sample trays, from the left side to the right side of the tray compartment, are designated A, B, C, D, and E. Each sample tray holds up to 40 standard 1.8 mL vials for a total capacity of 200 samples. Overlays allow the sample trays to accommodate different vial sizes. The microwell carrier can hold up to three low-density 96-well microplates or up to three high-density 384-well microplates. The microplates are designated A, B, and C. The tray compartment door contains a magnetic switch. The magnet is located in the door and the switch is attached to the chassis. When you open the door, the switch signals the autosampler that the door is open. If you select the Verify Door Is Closed check box when you configure the autosampler, the XYZ arm will automatically move to the back of the tray compartment when you open the door so that you can remove trays or replace vials. Opening the door while the autosampler is making an injection does not interrupt the current run. The XYZ arm moves to the back of the compartment after the injection is complete, whereupon the sequence is halted and the tray can be removed. After you close the autosampler door, the sequence resumes. Injection System The main components of the injection system include the following: • Syringe Drive Assembly and Syringe Valve • Wash Bottle Reservoir and Tubing • Interchangeable Syringe • XYZ Arm Mechanism • Needle Assembly and Needle Tubing Assembly • Injection Port and Transfer Tubing Assembly • Injection Valve and Sample Loop 8 Syringe Drive Assembly and Syringe Valve The syringe drive assembly consists of a stepper motor drive mechanism, a syringe valve, and fittings that hold the interchangeable syringe. The syringe drive assembly is mounted to the front of the autosampler with three mounting pins. On the back of the assembly, holes with grommets mate with these pins. These rubber grommets minimize the effects of vibration and cause the connection between the syringe drive assembly and the body of the autosampler to feel slack. See Figure 7.

In the wash bottle position, solvent is drawn into the syringe barrel as the syringe plunger descends. In the needle position, sample is drawn into the needle tubing as the syringe plunger descends and is pushed out of the needle tubing assembly as the syringe plunger ascends. Sample is never drawn into the barrel of the syringe. Note The needle tubing holds approximately 560 μL of solvent. If you have installed the 2500 μL standard syringe (which must be special ordered) and you plan to make large volume injections, ensure that you have also installed the 1-mL needle tubing extension that is shipped with this syringe. Wash Bottle Reservoir and Tubing Thermo Electron Corporation The wash bottle rests in the solvent platform on the top of the Surveyor Plus tack. It is connected to the syringe valve by way of the wash bottle tube. Both of the direct commands, Flush (from bottle) and Wash Needle (from bottle), draw solvent from the wash bottle. In addition, both the partial loop injection and the no waste injection modes draw transfer solution from the wash bottle. If the wash bottle runs dry, the wash bottle tubing and the syringe barrel will fill with air. If the syringe runs dry, the autosampler cannot draw sample into the needle tubing. Surveyor Plus Getting Started with Xcalibur 9 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus Interchangeable Syringe The standard configuration for the Surveyor Autosampler Plus consists of a 250 μL concentric syringe. The concentric syringe consists of a small, inner plunger, and a larger, outer plunger. See Figure 8. Inner Plunger Outer Plunger Figure 8. Concentric Syringe The inner plunger is used to draw and deliver sample amounts equal to or less than the maximum capacity of the syringe, which is 265 μL for the 250 μL concentric syringe. The outer plunger is used to draw and expel large volumes of solvent. Concentric syringes are available in 100, 250, and 500 μL sizes. In addition, a 2500 μL standard syringe is available. The volume of the outer plunger region, which is 565 μL, is the same for all three concentric syringes. The size of the inner plunger and the injection mode determine the available injection volume range. Because injections are always performed by using the inner plunger of the syringe, the size of the syringe does not affect the precision of an injection. However, for sample preparation routines, the outer plunger of the syringe is used for solvent transfers larger than the nominal size of the syringe. Solvent transfers performed with the outer plunger of the syringe are less precise than those performed with the inner plunger. Therefore, you might want to order the 500 μL concentric syringe or the 2500 μL standard syringe if you plan to use the autosampler to routinely perform sample dilutions. XYZ Arm Mechanism 10 Surveyor Plus Getting Started with Xcalibur The XYZ arm mechanism moves the needle along the x-y plane to the requested vial or well location. After the needle is positioned above the vial or well, the XYZ arm mechanism lowers the needle along the z-axis to the Thermo Electron Corporation 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus requested needle height. After the needle withdraws sample, the XYZ arm mechanism moves along the x-y plane, back to the home position, which is above the injection port of autosampler. The needle is then lowered into the injection port where it expels the sample. IMPORTANT Because the XYZ arm moves to the sample position to withdraw sample, it is important that you do not place objects taller than 1.8 inches into the tray compartment. Tall objects will stall the XYZ arm. If you select the Verify Door Is Closed check box when you configure the autosampler, the XYZ arm will automatically move to the back of the tray compartment when you open the door so that you can remove trays or replace vials. When you submit a Wash Needle direct command from the data system, the XYZ arm mechanism moves the needle to the wash station position. When you submit a Remove Needle direct command from the data system, the XYZ arm mechanism moves to the middle front of the tray compartment to allow easy access to the needle tubing assembly. Needle Assembly and Needle Tubing Assembly The needle assembly consists of a blunt-tip needle, a latch nut, a flag, a compression spring, and a 10-32 fitting that connects to the needle tube assembly. See Figure 9. The needle is inserted into the needle mount on the XYZ arm. Fitting to Syringe Valve Needle Assembly 10-32 Fitting PEEK Fitting to Needle Assembly Figure 9. Needle Guide Needle tubing assembly and needle assembly Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 11 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus The needle tube assembly consists of a piece of low-pressure tubing, a PEEKTM fitting that connects to the needle assembly, a fitting and flangeless ferrule that connects to the right side of the syringe valve, and a needle tube guide that is inserted into the X-axis positioning frame. To prevent the needle tubing from interfering with the movement of the XYZ arm, the needle tubing is secured with a clip on the Z-axis of the XYZ arm and a clip on the X-axis positioning frame. In addition to routing the needle tubing through these clips, make sure that you route the needle tubing behind the syringe drive assembly as you mount it. Injection Port and Transfer Tubing Assembly The injection port of the autosampler is located behind the syringe drive assembly. A 0.012-in. ID transfer tube connects the injection valve of the autosampler to port 2 of the Valco injection valve. See Figure 10. Note The label attached to the transfer tube assembly specifies its internal volume. You must enter this value in the Surveyor Autosampler Plus Configuration dialog box. See “Configuring the Surveyor Autosampler Plus” on page 28. Wash Station Transfer Tube Assembly Label (specifying the Dead Volume) Injection Port 22µL Transfer Tube Figure 10. Injection port and transfer tube 12 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Injection Valve and Sample Loop Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus The injection valve is a six-port Valco valve that introduces sample onto the column by way of the sample loop. The sample loop is a section of stainless steel tubing with end fittings. It is an interchangeable part that is attached to the Valco valve at ports 1 and 4. The Surveyor Autosampler Plus ships with a 25 μL sample loop. The available sizes are listed in Table 1. Table 1. Available sample loop sizes Sample Loop Size (μL) Part Number 5 00109-99-00007 10 00109-99-00008 20 00109-99-00009 25 00109-99-000010 50 00109-99-000011 100 00109-99-000012 500 00109-99-000013 1000 00109-99-000014 There are two positions for the six-port injection valve: • Fill Position • Inject Position Fill Position In the fill position, the sample loop is isolated from the mobile phase stream. As the mobile phase bypasses the sample loop, sample is pushed into the front of the loop that is connected to port 1 of the Valco injection valve. After the loop is filled, excess solution is pushed out the back of the loop to waste. See Figure 11. Transfer Tubing 1 2 To Column 6 3 To Waste 4 Mobile Phase Wash Solvent 5 From Pump Figure 11. Injection valve in the fill position Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 13 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus Inject Position In the inject position, mobile phase enters the sample loop from the back, backflushing the contents of the loop onto the column. Excess sample left in the transfer tube is expelled directly to waste. To allow ample rinsing of the sample loop with mobile phase, the injection valve remains in the inject position during the entire run. See Figure 12. Transfer Tubing 1 2 To Column 6 3 To Waste 4 Mobile Phase Wash Solvent 5 From Pump Figure 12. Injection valve in the inject position Injection Modes The Surveyor Autosampler Plus can operate in any of the following three modes: • No Waste Injection Mode • Partial Loop Injection Mode • Full Loop Injection Mode The optimum injection mode depends upon the amount of sample that you have and the degree of precision that your application requires. No Waste Injection Mode The no waste injection mode is a technique that withdraws only the exact amount of sample requested from the sample vial. Of the three injection modes, the no waste injection mode uses the least amount of sample, but it is also the least precise. Use this injection mode to conserve sample. The minimum allowable injection volume is 0.1 μL. Note To perform accurate no waste injections, use a sample loop that is at least 5 μL larger than the injection volume. 14 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Partial Loop Injection Mode Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus The partial loop injection mode is a technique that withdraws 22 μL of excess sample from the vial in addition to the requested injection volume. Approximately one-half of the excess volume is expelled to waste before the center of the sample bolus is metered into the front of the sample loop. The second portion of excess sample is expelled to waste after the sample bolus is backflushed onto the column. Partial loop injections are useful when you have a limited volume of sample. Using the partial loop injection mode, you can inject variable amounts of sample, ranging from a minimum of 0.1 μL to a working maximum of one-half the volume of your sample loop. This maximum volume limitation is caused by the laminar flow of fluid within the stainless steel sample loop. Note To make precise partial loop injections, use a sample loop that is at least twice the size of the injection volume. Full Loop Injection Mode The full loop injection mode is a technique that withdraws a sample volume from the vial that is sufficient to overfill the sample loop by a minimum factor of two. Because the actual injection volume is determined by the physical size of the sample loop, not the metering action of the stepper motor, a full loop injection is very reproducible. However, because the intent of the full loop injection mode is to completely fill the sample loop, you cannot inject variable amounts of sample. Full loop injection is useful when you want maximum precision and have unlimited sample. If you want to change the injection volume, you must change the sample loop size. For the available loop sizes, see Table 1 on page 13. Note In Xcalibur, full loop injections are limited to the size of the configured sample loop. In the full loop injection mode, the autosampler withdraws a large excess of solution from the sample vial according to the following equation: Amount Withdrawn = 3 × Injection Volume + Dead Volume + 7.5 μL Where: Dead Volume = Volume of Transfer Tube + Volume of Injection Port and Rotor Slot Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 15 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor Autosampler Plus This equation is valid until the maximum capacity of the syringe is reached, at which point only the maximum capacity of the syringe is withdrawn. The maximum capacity of the 250 μL concentric syringe is 265 μL. Temperature Control The full-featured Surveyor Autosampler Plus has two built-in temperature control features: • Tray Temperature Control • Column Oven Control Tray Temperature Control Column Oven Control The tray temperature control feature provides temperature control of the samples in the range from 0 to 60 °C. A Peltier device maintains the tray temperature. The built-in column oven controls the temperature of the air surrounding the chromatographic column. Isothermal temperature control is achieved using a Peltier device. The Peltier device is a solid-state, heat-transferring assembly used to heat or cool the column oven. The range of temperature control is 5 to 95 °C. Between the analytical pump and the autosampler injection valve, the mobile phase is diverted through approximately 120 cm of 0.020-in. ID stainless steel high-pressure tubing that is located behind the column oven. As it passes through this tubing, the mobile phase equilibrates to the temperature of the column oven before it reaches the Valco injection valve. Although it is useful for temperature sensitive applications, this additional tubing also adds 250 μL of gradient delay volume to the Surveyor Plus LC system. If you are performing low flow gradient applications, you might want to bypass this tubing by connecting the outlet of the pump directly to port 5 of the Valco injection valve. 16 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Surveyor PDA Plus Detector Introduction to the Surveyor Plus Integrated LC/MS System Surveyor PDA Plus Detector The Surveyor PDA Plus Detector is a full-featured, time-programmable, photodiode array detector. Detection can be carried out in the full ultraviolet-visible range from 190 to 800 nm. Data can be taken in this range at a rate of up to 20 Hz with 20-bit digital conversion. The optimal location for the PDA detector is above the autosampler and below the solvent platform. The PDA detector is controlled remotely over an Ethernet communication link from a PC using the Xcalibur software. The PDA detector consists of a dual-light source, an optical bench, a photodiode array, a low voltage power supply, several printed circuit boards (PCBs), and four status LEDs. The dual-light source includes a deuterium lamp for detection in the ultraviolet wavelength range (190 to 360 nm) and a tungsten-halogen lamp for detection in the visible wavelength range (360 to 800 nm). There is some overlap between the two lamps in the 300 to 500 nm range. Attenuators are used to adjust the intensity of light reaching the photodiode array. The optical bench contains a beam combiner, focusing lens, filter wheel, flow cell, beam shaper, folding mirror and grating. The beam combiner reflects the light coming from the tungsten-halogen lamp so that it is parallel to and coincident with the light from the deuterium lamp. The combined beam is then focused on the inlet window of the flow cell through the filter wheel. The standard filter wheel has two positions. Position 1 (Open) is used for normal operation. Position 2 contains a sealed, quartz cuvette filled with a holmium oxide / perchloric acid solution (NIST Traceable) and is used for wavelength accuracy verification and calibration. See Figure 13. Beam Combiner Focusing Lens Filter Wheel Beam Shaper Flow Cell Deuterium Lamp Attenuators Folding Mirror 1 x 512 Photo Diode Array Fixed Grating Tungsten-Halogen Lamp Figure 13. Optical Bench of the Surveyor PDA Plus detector Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 17 1 Introduction to the Surveyor Plus Integrated LC/MS System Surveyor UV/Vis Plus Detector Surveyor UV/Vis Plus Detector The Surveyor UV/Vis Plus Detector is a full-featured, time-programmable, variable-wavelength UV/Vis (ultraviolet / visible) absorbance detector. It operates in either the single wavelength mode or the dual wavelength mode. The wavelength range in the single wavelength mode is 190 nm to 800 nm. In the dual wavelength UV mode, the range is 190 nm to 450 nm. In the dual wavelength Visible mode, the range is 366 nm to 700 nm. The wavelength time table is available in all three modes. The time table can contain up to 10 lines. If the Zero On Wavelength Change feature is enabled, the absorbance of the baseline is re-zeroed between each line in the time table, even if the wavelengths remain the same. The absorbance of the baseline is not zeroed between the last two lines in the table. To provide a complete spectrum of ultraviolet and visible light, the detector uses a deuterium lamp for the UV range (190-365 nm) and a tungsten lamp for the visible range (366-800 nm). The lamps are protected by a cover with a special safety interlock to reduce the possibility of human exposure to harmful UV light. 18 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Communication with Xcalibur Introduction to the Surveyor Plus Integrated LC/MS System Communication with Xcalibur Communication with the Xcalibur data system is established with an Ethernet connection for the Surveyor LC Pump Plus, the Surveyor Autosampler Plus, the Surveyor PDA Plus Detector, and the Surveyor UV/Vis Plus Detector. To establish communications with each of these devices, you must connect one end of a Ethernet cable (shielded, category 5, RJ-45, 7-ft. length cable with ferrite) to the Ethernet port on the back panel of the device and the other end of the cable to an Ethernet switch. The Ethernet switch is connected by way of a second Ethernet cable to the PC on which the Xcalibur data system resides. The Xcalibur data system is connected to the Surveyor MS Pump Plus with a serial communication link. The MS pump accessory kit contains a serial cable with nine pin adaptors on each end. In addition to connecting the communication cables, you must also enter the appropriate stack addresses when you configure the devices of your instrument. The stack address that you enter when you add a device to the configuration for your instrument must match the Unit ID setting on the back panel of the device. For more information on configuring the Surveyor Plus LC devices, see Chapter 2, “Configuring Your Surveyor Plus LC Instrument.” Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 19 1 Introduction to the Surveyor Plus Integrated LC/MS System Synchronizing the Surveyor LC Devices Synchronizing the Surveyor LC Devices A system interconnect cable is used to coordinate the run control signals between the Surveyor Plus devices. Thermo Electron provides two versions of this cable: the older version has 5-combicon connectors and the newer version has 7-combicon connectors. See the Surveyor Plus Getting Connecting manual for details on connecting one of these cables to the devices in your Surveyor Plus stack. During a run the system issues the following sequence of run control signals: 1. A request to perform an injection is issued from the data system PC. 2. When the autosampler becomes ready, it issues the A/S Ready signal. The autosampler goes into the Ready state when all of the configuration and Instrument Method conditions are met. These conditions can include the following: the tray door is closed, and the sample tray and column oven temperature zone readings are within tolerance of their setpoints. 3. When the pump pressure stabilizes, the pump issues the Pump Ready signal to the autosampler. Note The Surveyor LC Pump Plus issues a Pump Ready signal. The Surveyor LC Pump does not issue this signal. The autosampler switches the injection valve to the load position, and then loads sample into the sample loop. 4. The autosampler issues the Gradient Start signal to the pump. This signal commands the pump to start its gradient program. 5. When its piston cam reaches the home position, the pump issues the Inject Hold release signal to the autosampler. Note The Surveyor LC Pump Plus issues an Inject Hold Release signal. The Surveyor LC Pump does not issue this signal. 6. The autosampler injects the sample and issues a momentary Inject Out signal to the detector. The injection valve of the autosampler switches to the inject position, allowing the mobile phase to backflush the contents of the sample loop onto the column. The detector starts to collect data. 20 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 1 Status LEDs Table 2. Introduction to the Surveyor Plus Integrated LC/MS System Status LEDs Each of the Surveyor Plus LC devices has a panel of four status LEDs (light-emitting diodes) located on its front-right door. All of the devices have these three LEDs: Power, Comm, and Run. The fourth LED on the detector is the Lamps LED. The fourth LED on the autosampler in the Temp LED.

Each device has an Ethernet port on its back panel. A shielded, CAT 5 Ethernet cable with ferrite is used to connect each device to an Ethernet switch, which in turn is connected by way of an Ethernet cable to the data system computer. The Unit ID setting on the back panel of the LC pump, autosampler, and detector must match the Stack Number in the configuration. Unlike the other Surveyor Plus devices, the Surveyor MS Pump Plus communicates with the Xcalibur data system through an RS232 serial connection. Before you configure your instrument from the data system, do the following: 1. Check the setting of the rotary switches on the back panels of your devices. 2. If you are using the MS pump, verify that the serial communication cable connecting the MS pump to your PC is attached to COM port 1. 24 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 2 Configuring the Surveyor Plus LC Devices Configuring Your Surveyor Plus LC Instrument Configuring the Surveyor Plus LC Devices To configure your Surveyor Plus LC Instrument, perform the following procedures in this section as listed: 1.

Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 43 3 Preparing for Operation Checking the Status of the LC Devices Viewing the Status of Each Device The Surveyor Plus Integrated LC system contains an autosampler and an analytical pump. In addition, your system might contain an optional PDA or UV/Vis detector. Check the status of each device by clicking its name in the Device Tree list. The status information for a specific device is displayed in the lower portion of the Status page. The Status view for the full-featured Surveyor Autosampler Plus contains four pages: AS Status, Oven, Tray, and Error Log. See Figure 29. The Status view for the Surveyor Autosampler Plus Lite contains two pages. The status page for the Surveyor Autosampler Plus displays one of the following eight states: 1. Initializing appears while Xcalibur is attempting to connect to the autosampler. 2. Ready to download appears after communication has been established with the autosampler and after each run has ended. 3. Ready to run appears for a very brief period after a method is downloaded to the autosampler and before the injection process has begun. 4. Running appears during the injection process. If the method contains a time function for the autosampler, the running status message is displayed until the time function has expired. 5. Direct control appears when the direct control or calibration windows are open. 6. Busy appears while the autosampler is performing a direct control operation. 7. Error appears when an error condition other than the loss of communication occurs. 8. Off appears after Xcalibur has attempted to connect to the autosampler and failed five times. The most common reasons for Xcalibur failing to connect with the Surveyor Autosampler Plus are that the 10-pin connector of the syringe drive assembly is unplugged from the autosampler or that the XYZ arm is stalled. 44 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 3 Preparing for Operation Checking the Status of the LC Devices Figure 29.

Schematic of solvent path for flushing the syringe Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 57 3 Preparing for Operation Checking the Firmware Version of the Surveyor LC Pump Checking the Firmware Version of the Surveyor LC Pump If your Surveyor LC Pump has a firmware version below 2.0, it does not send a Pump Ready signal to the Surveyor Autosampler. If you selected either of the Input check boxes in the Signal Polarity page when you configured the Surveyor Autosampler, the status of the Surveyor LC Pump will indefinitely remain at Waiting for Contact Closure after you make an injection. To prevent this mismatch, verify the firmware version of your Surveyor LC Pump. If necessary, modify the configuration for the autosampler signal polarities accordingly. To check the version of your Surveyor LC Pump Plus 1. Open the Instrument Setup window as described on page 51. 2. In the Instrument Setup viewbar, click the Surveyor LC Pump button to open its Instrument Setup view. 3. From the menu bar, choose Surveyor LC Pump > Direct Control > Configuration to open the Configuration – Surveyor LC Pump Direct Control dialog box. See Figure 42. 4. Note the firmware version of the Surveyor LC Pump. If the version is lower than 2.0, check the configuration of the Surveyor Autosampler. See “Configuring the Surveyor Autosampler Plus” on page 28. Figure 42. Configuration – Surveyor LC Pump Direct Control dialog box 58 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 3 Preparing for Operation Priming the Pulse Dampener of the MS Pump Priming the Pulse Dampener of the MS Pump Before you can operate your MS pump, you must prime its built-in pulse dampener. Priming the pulse dampener involves filling the dampening coil of the pulse dampener with a solvent such as methanol or isopropanol. After the coil is filled with solvent, it can effectively dampen pressure pulsations from the rest of your system. Closing the manual bleeder valve after you fill the coil shuts the dampening coil off from the mobile phase stream. See Figure 43. However, only a permeable membrane separates the mobile phase stream from the dampening coil. Therefore, if you use buffered mobile phases, there will be a gradual buildup of electrolytes in the dampening coil. Due to the pressure gradient, the reverse does not occur. Therefore, you do not need to match the priming solvent to the mobile phase because the solvent in the coil cannot diffuse into the mobile phase stream. If you are not pumping buffered mobile phases, you need to prime the pulse dampener only before you initially operate the MS pump. In contrast, you will occasionally need to reprime the pulse dampener if you are pumping buffered mobile phases. Flushing the pulse dampener following the use of buffered eluents helps to prevent salt build-up and its associated corrosion. Note Do not fill the pulse dampener with an aggressive acid or a buffered solution. The recommended filling solvents are methanol, acetonitrile, or isopropyl alcohol. If you accidentally fill the pulse dampener with an acidic or buffered solvent, flush the loop with a miscible solvent, and then refill it with methanol, acetonitrile, or isopropyl alcohol.

Pulse dampening assembly for MS pump Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 59 3 Preparing for Operation Priming the Pulse Dampener of the MS Pump To prime the pulse dampener 1. Fill a solvent reservoir with particulate-free, HPLC grade methanol. 2. Connect an HPLC column or a flow restrictor to the pulse dampener outlet. 3. Insert the tip of the 10 mL syringe into the tubing that is connected to the manual bleeder valve of the pulse dampener. Then, open the valve by turning it counter-clockwise. 4. Set the flow rate to 1 mL/min (1000 μL/min). 5. Fill the loop completely, to expel any air that might be trapped in the dampener loop. 6. Set the flow rate to one that is appropriate for your system. 7. Close the manual bleeder valve of the pulse dampener (see Figure 44) by turning the valve clockwise. Unless you need to refill the dampener loop of the pulse dampener with fresh solvent, keep the manual bleeder valve closed. Outlet of Pulse Dampener Manual Bleeder Valve with Attached Tubing Figure 44. Manual bleeder valve and attached tubing 60 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 3 Preparing for Operation Calibrating the PDA Detector Calibrating the PDA Detector There are two types of calibration for the PDA detector: • Dark Current Calibration • Wavelength Calibration You must perform both calibrations after the initial installation of your detector. Thereafter, Thermo Electron recommends that you perform a dark current calibration monthly and a wavelength calibration whenever you move your detector or it is physically jolted. The instructions for performing these calibrations are included in “Verifying the Performance of the PDA Detector” on page 174. Dark Current Calibration The function of the dark current calibration is to measure and correct for the background signal that is produced by the photodiode array. Even when both lamps are turned Off, the array still produces a small amount of background signal. Typical dark current values range from 1500 to 3000 counts. Before intensity values can be converted to absorbance units, the dark current must be subtracted from the intensity measurements. Following dark current calibration, light intensity values are automatically corrected for dark current. Remember that because the dark current signal is a function of temperature both lamps must be On during calibration. You typically warm-up the lamps for one hour before making injections. Therefore, it is important to warm-up the lamps for one hour before performing a dark current calibration to ensure that the temperature within the detector during calibration matches the temperature within the detector during normal operation. Perform a dark current calibration monthly. Wavelength Calibration The alignment of the spectrum on the diode array depends upon the physical alignment of various components of the optical bench. The alignment can become offset if the detector is sharply jolted, for example, in shipping. Such bumps and jars can slightly change the wavelength of light reaching the photodiode array. The automated wavelength calibration allows you to determine wavelength accuracy. It also allows the PDA detector to mathematically compensate for minor changes in the alignment of the components of the optical bench. Perform a wavelength calibration if you move the detector or if it receives a physical jolt. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 61 Chapter 4 Creating Instrument Methods To automate the control of your LC devices, you must create an Instrument Method from the Instrument Setup window of the Xcalibur data system. This chapter describes the instrument control parameters for your Surveyor Plus LC devices. It does not describe the instrument control parameters for your MS detector. For information on the instrument control parameters for your MS detector, see its Getting Started manual. To create an instrument method containing the appropriate chromatographic conditions, perform the following procedures that are provided in this chapter and that pertain to your LC devices in the order listed: 1. Opening the Instrument Setup Window 2. Entering the Method Parameters for the MS Pump 3. Entering the Method Parameters for the LC Pump 4. Entering the Method Parameters for the Autosampler 5. Entering the Method Parameters for the PDA Detector 6. Entering the Method Parameters for the UV/Vis Detector 7. (Optional) Adding a Sample Preparation Routine to the Method 8.

To open the Surveyor MS Pump view, click the Surveyor MS Pump icon in the Viewbar of the Instrument Setup window. If you are unfamiliar with the Surveyor MS Pump Plus, review the description of its instrument control parameters before you create the pump program. This section contains the following topics: • Parameters for the Surveyor MS Pump Plus • Programming the Surveyor MS Pump Plus Parameters for the Surveyor MS Pump Plus The following topics describe the instrument control parameters for the Surveyor MS Pump Plus: • Surveyor MS Pump View - General Page • Surveyor MS Pump View - Gradient Page Surveyor MS Pump View - General Page The Surveyor MS Pump View – General page has the following areas: Parameters for the Pump The General page contains the parameters listed below. The values that you enter in these boxes will be reported in the Instrument Method report attached to the raw file. This report can be accessed in the Qual Browser view by choosing View > Reports > Instrument Method. Name Use this box to select the pump if you are running a dual pump system. Comments Use this box to enter more information about the method, for example, the type of LC column being used. Solvent Select the check box to the left of these boxes to make them available, and then type a description of the solvent. Operating mode Use this list to select the operating mode: 0 to 7000 PSI (standard) or 0 to 16000 PSI (ultra-high performance). Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 65 4 Creating Instrument Methods Entering the Method Parameters for the MS Pump Start settings Use this list to select how runs are triggered. The available selections are Autosampler logic and manual. Select Surveyor AS injection logic if you want to use the autosampler as the start instrument that triggers the run. Method finalizing Use this list to select the mobile phase composition at the end of the run. the available selections are First line conditions, Last line conditions, and Stop after the end. Select Stop after the end if you want to use the method to turn off the pump flow. Min pressure Use this box to enter a minimum pressure below which the pump will stop operating. Entering an appropriate minimum pressure prevents the pump from operating when the solvent reservoirs have run dry or the system plumbing has developed a leak. Running the pump without solvent will quickly ruin the piston seals. The range is 0 to 400 bar (5800 psi) with a default value of 0 bar. Type a value that is well below the typical operating pressure for your application in this box. In the event that the pressure falls below this limit, the pump automatically stops and sends an error message to the computer. Max pressure Use this box to enter a maximum operating pressure for the pump. Entering an appropriate maximum pressure prevents the pump from operating with a restriction on the outlet side of the pump. Excess pressure can damage the HPLC column and any other component between the restriction and the pump. The range is 0 to 400 bar (5800 psi) with a default value of 0 bar. In this box, type a value that is well above the typical operating pressure for your application, but also below the pressure that can damage your system. In the event that the pressure rises above this limit, the pump automatically stops and sends an error message to the computer. Pressure stability Use this box to adjust the stability condition required for the pump to go into a Ready mode. A lower value requires greater pressure stability before the pump becomes Ready. A higher value is more forgiving of pressure pulsations. Home before run This check box is available when you select Manual from the Start settings list. Selecting this check box increases the reproducibility of chromatographic runs when you are performing manual injections. Pressure units Use this list to select the units for the backpressure readout. The available selections are bar, PSI, and MPa. Surveyor MS Pump View - Gradient Page The Surveyor MS Pump View – Gradient page has the following areas: • Gradient Table Area • Gradient Profile Area 66 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the MS Pump Gradient Table Area Each row in the Gradient Table defines the solvent composition and flow rate for a specific time point. Between time points, the solvent composition changes linearly, whereas, the flow rate changes as a discontinuous step-function. The Gradient Table can contain up to 80 time lines. The time parameter (min box) specifies at what point in the run the associated solvent composition and flow rate become effective. The first time line remains set to 0 min. The solvent composition parameters (%A, %B, %C, and %D boxes) work interactively with each other and specify the mobile phase composition at the time point specified in the associated Min box. The mobile phase composition changes linearly between two consecutive time points. The default composition setting is 100% A. The flow rate parameter (μL/min) box specifies the flow rate of the mobile phase at the time specified in the associated Min box. The default setting flow rate setting is 1000 μL/min. Gradient Profile Area The Gradient Profile area graphically displays the values entered in the Gradient Table. The Y-axis represents percent composition and the X-axis represents time in minutes. Each solvent is color-coded for better visualization of the programmed gradient. Programming the Surveyor MS Pump Plus The Surveyor MS Pump Plus contains a built-in solvent proportioning assembly that is capable of proportioning up to four solvents to create binary, tertiary, and quaternary mobile phases. This capability reduces the need to make premixed mobile phases. You can run the MS pump in either the isocratic mode or the gradient mode. In the isocratic mode, the same proportions of solvent are maintained throughout the run. To program the pump 1. In the General page (see Figure 46), type or select the following: a.

An example of a gradient program for the LC pump Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 75 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Entering the Method Parameters for the Autosampler The parameters for the autosampler are entered in the Surveyor Autosampler Instrument Setup view. To open this view, click the Surveyor Autosampler icon in the Viewbar of the Instrument Setup window. If you are unfamiliar the Surveyor Autosampler Plus, review the description of the instrument control parameters for the Surveyor Autosampler before you enter your injection parameters. This section contains the following topics: • Parameters for the Surveyor Autosampler Plus • Programming the Surveyor Autosampler Plus Parameters for the Surveyor Autosampler Plus The Surveyor AS Instrument Setup view contains four pages. The following three pages are described in this section. The Sample Preparation page is described in the next section “Adding a Sample Preparation Routine to the Method” on page 98. • Surveyor AS Method Page • Reservoir Content Page • Timed Events Page Surveyor AS Method Page 76 Surveyor Plus Getting Started with Xcalibur You set the injection and the temperature control parameters for the autosampler in the Surveyor AS Method page. See Figure 52. Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Figure 52. Surveyor AS Instrument Setup view – Surveyor AS Method page The available parameters are: • Injection Volume • Needle Height From Bottom • Syringe Sample Speed • Flush Volume • Flush/Wash Source • Wash Volume • Flush Speed • Post Injection Valve Switch Time • Loop Loading Speed • Injection Mode • Tray Temperature Control • Column Oven Control Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 77 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Injection Volume The Injection Volume box displays the injection volume in microliters of sample that will be placed in the sample loop prior to opening the loop up to the mobile phase stream. The available injection volumes are determined by the size of the syringe. For the No Waste and the Partial Loop injection modes, the sample loop size limits the practical injection volume range. For optimal performance, refer to the following suggested injection volumes: • For no waste injections, limit the injection volume range to a minimum of 0.5 μL and a maximum equal to 5 μL less than the nominal sample loop size. • For partial loop injections, limit the injection volume range to a minimum of 0.1 μL and a maximum equal to one-half the nominal sample loop size. • For full loop injections, the Injection Volume box is grayed out, limiting the injection volume to the configured sample loop size. The Surveyor Autosampler is shipped with a 25 μL sample loop. Needle Height From Bottom The Needle Height From Bottom box displays the height in millimeters from the bottom of the vial or well at which the needle withdraws liquid. The range of values is 0.1 to 18.0 mm in increments of 0.1 mm. The default value is 2.0 mm. Figure 53 shows the needle descending to a depth of 2 mm from the bottom of a standard 1.8 mL vial. 2mm Figure 53. View of needle descending to 2 mm from the bottom of a vial 78 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Syringe Sample Speed The Syringe Sample Speed box displays the rate in microliters per second at which the syringe withdraws liquid from a tray vial or a plate well. The syringe speed range is determined by the size of the syringe. You select the size of the syringe in the Syringe Type list in the Communication page of the Surveyor Autosampler Configuration dialog box. Use a syringe speed lower than the default for viscous samples. Also use a syringe speed lower than the default for samples of very low viscosity or surface tension to prevent the sample bolus from breaking apart during the transport process. Flush Volume The Flush Volume box displays the volume in microliters of liquid that is used to flush the syringe. During an internal flush, the syringe needle is moved to the injection port to dispense a specified volume of solvent from the bottle or reservoir vial. The injector is switched to the Inject position to prevent solvent from entering the loop. The internal flush is used to remove residual sample. The range of values is 0.0 to 6000.0 μL. The default volume is 400.0 μL. Note A flush is accomplished by pushing the amount of solvent that you specify into the injection port of the autosampler, through the transfer tubing to the Valco injection valve, and out port 3 of the injection valve to waste. If the specified flush volume exceeds the syringe volume, then the autosampler takes multiple draws from the reservoir or bottle to equal the specified flush volume. Flush/Wash Source The Flush/Wash Source list displays the flush/wash source. The flush/wash source can be either the wash bottle or a reservoir vial (RV1 to RV4). To change the flush/wash source, click the arrow to display the list of source options. Wash Volume The Wash Volume box displays the volume in microliters of liquid that is used to wash the needle. During an external wash, the syringe needle is moved to the wash station to dispense a specified volume of solvent from the bottle or reservoir vial. The range of volumes is 0.0 to 6000.0 μL. The default value is 0.0 μL. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 79 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Note A wash is accomplished by washing the interior and exterior of the syringe needle with solvent. If the specified wash volume exceeds the syringe volume, then the autosampler takes multiple draws from the reservoir or bottle to equal the specified wash volume. Flush Speed The Flush Speed box displays the rate in microliters at which the syringe draws flush solvent into its chamber and expels flush solvent through the needle during a flush cycle. The range of values for the concentric syringes is 0.83 to 661.38 μL/s. The default value is 100.0 μL/s. The range of values for the 2500 standard syringe is 8.27 to 330.85 μL/s. The default value is 82.71 μL/s. Note The default flush speed of 100 μL/s for the 250 μL concentric syringe is the maximum flush speed for a solvent of high viscosity such as water. At high flush speeds, viscous solvents cause the autosampler to make a grinding sound. Post Injection Valve Switch Time The default time for the Post Injection Valve Switch Time box is 0. If you leave this value at 0, the valve remains in the inject position throughout the entire run, which allows ample rinsing of the sample loop with mobile phase. Any nonzero value equal to or greater than 0.1 min is the time at which the injection valve will switch from the inject position to the load position following an injection. To reduce the gradient delay volume for low flow gradient applications, consider switching the injection valve from the inject position to the load position during the run by entering a nonzero value in this box. In the load position, flow from the pump bypasses the sample loop and goes directly to the column. Loop Loading Speed The Loop Loading Speed box displays the speed at which the sample is loaded onto a guard column or a trap. This parameter is only available in the no waste injection mode. The syringe pushes the sample bolus to the injection port at syringe speed. The injection valve then switches to the load position and the syringe meters the sample bolus onto the guard column or trap at loop loading speed. 80 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Injection Mode The option buttons in the Injection Mode area allow you to select the injection mode. The injection modes are No Waste, Partial Loop, and Full Loop and are described in detail in Chapter 1, “Introduction to the Surveyor Plus Integrated LC/MS System.” See “Injection Volume” on page 78 for information on the appropriate injection volumes for the three injection modes. Tray Temperature Control You to set the temperature for the sample tray in the Tray Temperature Control area. The temperature control feature performs heating or cooling of the sample tray to establish an isothermal condition. You select the Enable Tray Temperature Control check box to activate the Temperature box. The Temperature box displays the temperature of the sample tray in degrees Celsius. The range of values is 0 to 60 °C. The default value is 30 °C. The precision is 1 °C. As a safety feature, a thermostat disables power to the sample tray if the temperature reaches 65 °C. Column Oven Control You to set the temperature for the column oven in the Column Oven Control area. The temperature control feature performs isothermal heating or cooling of the column oven to establish an isothermal condition. You select the Enable Column Oven Control check box to activate the Temperature box. The Temperature box displays the temperature in degrees Celsius of the column oven. The range of values is 5 to 95 °C. The default value is 30 °C. The precision is 1 °C. As a safety feature, a thermostat disables power to the column oven if the temperature reaches 110 °C. Reservoir Content Page You enter descriptions for the contents of the four reservoir vials and the wash solvent in the Reservoir Content Page shown in Figure 54. You can type up to 80 characters in each box. To open the Reservoir Content page, click the Reservoir Content tab in the Surveyor AS Instrument Setup View. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 81 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Figure 54. Surveyor AS Instrument Setup view – Reservoir Content page Timed Events Page You set timed events for the time function terminals (TF1 to TF4) located on the rear panel of the Surveyor AS (See Figure 56) in the Timed Events page shown in Figure 55. You can use the TF terminals to control peripheral devices that are not controlled by Xcalibur. Timed Event output signals are issued after the Inject Out signal in the signal sequence. See “Synchronizing the Surveyor LC Devices” on page 20. The TF terminal output signal is LO (Closed) by default. You can change the polarity of the TF output signal to HI (Open) by selecting the Timed Events Active High check box in the Signal Polarity page of the Surveyor Autosampler Configuration dialog box. To display the Timed Events page, click the Timed Events tab in the Surveyor AS Instrument Setup view. You program timed events by adding entries to the Timed Events table. The Timed Events table contains Time boxes and event (TF1, TF2, TF3, and TF4) lists. In the Time box, you specify the time in minutes when the Surveyor Autosampler TF terminal (TF1 to TF4) signals an event. Time 0.0 is defined as the time when the Surveyor Autosampler issues an Inject Out signal. The range of values is 0.0 to 9999.9 min. In the event (TF1, TF2, TF3, and TF4) lists, you select whether the TF1, TF2, TF3, and TF4 output terminal is On or Off at the time specified in the Time box. 82 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler Figure 55.

In the Surveyor AS Method page (see Figure 52 on page 77) make the following entries and selections: a. Select an injection mode: Partial Loop, Full Loop, or No Waste. Then, do one of the following: • If you selected the Full Loop injection mode, continue at step 2d. The injection volume is automatically set to the configured value for the sample loop size. • If you selected the No Waste injection mode, go to step 2b. • If you selected the Partial Loop injection mode, go to step 2c. b. For the No Waste injection mode, select a loop loading speed from the Loop Loading Speed box. For most applications, leave the loop loading speed at its default value. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 83 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler c. For the Partial Loop or No Waste variable volume injection modes, type an injection volume in the Injection Volume box. See “Injection Volume” on page 78 for information on the appropriate injection volumes for these injection modes. d. From the Needle Height From Bottom box, select the depth to which the needle of the autosampler will descend before it withdraws sample from the vial / well location. The allowable values are 0.1 to 18 mm. Entering a lower value causes the needle to descend closer to the bottom of the vial or well. The standard 1.8 mL vials supplied with the Surveyor Autosampler have a depth of approximately 20 mm. See Figure 53 on page 78. e. For most applications, leave the syringe speed at its default value (8 μL/s for the 250 μL concentric syringe). If you notice a break up of the sample in the needle tubing as the autosampler withdraws sample from a vial / well location, adjust the syringe speed. f. Type a volume from 0 to 6000 μL in the Flush volume box or leave the value at its default of 400 μL. g. Select a flush / wash solution from the Flush / Wash list. For most applications, select the Wash bottle. If you select one of the reservoir vial locations as your flush / wash source, remember to load the autosampler with a reservoir vial. See “Tray Compartment” on page 7. h. For most applications, leave the wash volume at its default value of 0 μL. If you want to wash the exterior of the needle after each injection, type a value between 0 to 6000 μL in the Wash Volume box. i. Leave the flush speed at its default (250 μL/s for the 250 μL concentric syringe) if you are using a flush solvent of low viscosity such as methanol. Reduce the flush speed if you are using water or a methanol / water mixture as the flush solvent. Note If the flush speed is too high, the autosampler makes a grinding noise as it performs a flush. j. 84 Surveyor Plus Getting Started with Xcalibur For most applications, leave the post injection valve switch time at its default of 0 min. This leaves the sample loop in the inject position during the entire run, which generally allows ample rinsing of the sample loop between injections. Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the Autosampler k. For the full-featured Surveyor Autosampler Plus, do the following: • If you want to control the temperature of the tray compartment, select the Enable Tray Temperature Control check box. Then, type an appropriate temperature from 0 to 60 °C in the Temperature box. • If you want to control the temperature of the LC column, select the Enable Column Oven Control check box. Then, type an appropriate temperature from 5 to 95 °C in the Temperature box. Controlling the temperature of the LC column increases the reproducibility of the chromatographic retention times. 3. In the Reservoir Content page (see Figure 54 on page 82), identify the solvents contained in the 15 mL solvent reservoir vials and the 1 L wash bottle by typing their names in their respective boxes. 4. If you want to use the Surveyor Autosampler Plus to control external devices make the appropriate entries in the Timed Events page (see Figure 55 on page 83). 5.

To open the Surveyor PDA Plus view Click the Surveyor PDA Plus icon in the Viewbar of the Instrument Setup window. This section contains the topics listed below. If you are unfamiliar with the Surveyor PDA Plus Detector, review the description of its instrument control parameters before you program it. • Parameters for the Surveyor PDA Plus Detector • Programming the Surveyor PDA Plus Detector Parameters for the Surveyor PDA Plus Detector The Surveyor PDA Method page contains parameters that define the data that is collected during an analysis. See Figure 57. The Surveyor PDA Method page contains the following areas: • Run Area • Units Area • Spectra Area • Channels Area • Timed Events Area 86 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector Figure 57. Surveyor PDA Plus Instrument Setup View – Surveyor PDA Plus Method page Run Area The run area box contains the following boxes: • Run Length Box • Filter Rise Time List Run Length Box The Run Length box specifies the time during which the detector will collect spectral and discrete wavelength data. The maximum run length is 600 minutes. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 87 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector Filter Rise Time List In the Rise Time list, you select the response time of the detector, in seconds, to the signal. Rise time is inversely proportional to the amount of baseline noise: the longer the rise time, the less noise detected. Setting the rise time to a value greater than one-tenth the width of the chromatographic peak at half-height results in peak broadening as shown in Figure 58. The one-second default value is appropriate for most LC applications. Note The baseline noise inevitably increases as the deuterium lamp reaches the limit of its expected lifetime. Track the expected signal to noise levels for your chromatographic method to determine an appropriate replacement schedule for the deuterium lamp. 0.1 s Rise Time 2 s Rise Time mAU 5 s Rise Time 10 s Rise Time Minutes Figure 58. Effect of rise time on band broadening Units Area In the Units area, you select the units that are displayed in the spectrum plots. You can select to display either absorbance (default) or intensity. Absorbance displays the absorbance signal from the detector. In this case, the X-axis corresponds to wavelength in nanometers. Intensity displays the light intensity detected by the photo diodes of the diode array. The X-axis, therefore in this case, corresponds to photo diode number. The controls in this area are the Wavelength/Absorbance option button and the Diode/Intensity option button. 88 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector There are 512 diodes in the Surveyor PDA diode array. Diodes 0 and 1 are not used. Diode 2 corresponds to wavelength 190 nm and diode 511 corresponds to 800 nm. This gives a spacing of 610 /510 diodes = 1.2 nm/diode. The data is interpolated to give integer values. Spectra Area To collect spectral scans, select the Collect Spectral Data check box, and then fill in the following scan parameters: • Start Wavelength • End Wavelength • Wavelength Step • Sample Rate • Filter Bandwidth Start Wavelength In the Start Wavelength box, you enter a starting wavelength for the scan. The range of acceptable values is from 190 to 800 nm. The default starting wavelength is 200 nm. End Wavelength In the End Wavelength box, you enter an ending wavelength for the scan data. The range of acceptable values is from 191 to 800 nm. The default ending wavelength is 600 nm. The end wavelength must be greater than the start wavelength and the difference between the end wavelength and the start wavelength must be an integral multiple of the wavelength step. Wavelength Step In the Wavelength Step box, you enter an appropriate scan data increment. The default is 1 nm. (At a value of 1 nm, the detector will collect data at every nanometer within the scan range.). Depending on the wavelength range, the allowable values are 1 to 610 nm. Note If you plan to create Spectrum files from the scan data acquired with this method, use a 1 nm wavelength step. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 89 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector Sample Rate In the Sample Rate list, you select an appropriate sample rate for your application. The acceptable values are 0.5, 1, 2, 4, 5, 10, and 20 Hz with 1 Hz being the default. This sampling rate is the rate at which data points are collected for each wavelength in the scan range. The size of your data files increases as the sampling rate and number of wavelengths scanned increases. Filter Bandwidth In the Filter Bandwidth box, you enter an appropriate bandwidth for the Savitsky-Golay filter. Increasing the value of the bandwidth filter can improve the signal-to-noise ratio for your chromatograms, but compromises spectral resolution. The default setting is 1.00 nm for the highest spectral resolution. See Figure 59, which shows the loss of spectral resolution for a spectrum of toluene as the bandwidth is raised from 1 nm to 11 nm. 1 nm Bandwidth 11 nm Bandwidth Figure 59. Spectra of toluene, effect of bandwidth on spectral resolution 90 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector Bandwidth values are limited to the following subset of odd integers: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 43, 45, 47, and 49. In addition, the allowable scan range for a particular bandwidth is limited as follows: • Start Wavelength (minimum) = 190 nm + (bandwidth / 2) • End Wavelength (maximum) = 800 nm – (bandwidth / 2) According to these equations, the maximum scan range for a bandwidth of 49 nm is 214 nm to 776 nm. Note Wider bandwidths decrease both spectral noise and the resolution of the spectra. In general, the filter bandwidth should not exceed 10% of the bandwidth at half-height of the narrowest spectral feature of interest. Channels Area The Channels area contains option buttons to select None, One, Two or Three single-wavelength channels. There is also a sample rate box, which is applied to all chromatogram-channels (A, B, and, C). Sample Rate In the Sample Rate list, you select a data-sampling rate for the discrete channels. The available values are: 0.5, 1, 2, 4, 5, 10, and 20 Hz (1 Hz = 1 point per second), with the default of 10 Hz. A sampling rate that is too low can affect the integration of narrow peaks. None/A/B/C Select You must select the appropriate channel option button to collect data for that channel. You can select any combination of channels or none. Default is Three Discrete channels. Wavelength In the Wavelength box, you enter an appropriate wavelength for your application. The acceptable range of values is from 190 nm to 800 nm, in increments of 1 nm. The default wavelengths are 214, 254, and 280 nm. Note The combination of the bandwidth and wavelength settings cannot extend beyond the range of the detector. For example, a bandwidth of 49 nm is not allowed for a wavelength of 200 nm because it would require an analysis range from 176 nm to 224 nm. The maximum allowable bandwidth for 200 nm is 21 nm, which requires an analysis range of 190 nm to 210 nm. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 91 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector Filter Bandwidth In the Filter Bandwidth box, you enter an appropriate bandwidth for the Savitsky-Golay filtering. The acceptable range is from 1 to 49 nm in odd-number increments, with 1 nm meaning no filtering. The default value is 9 nm. Note Enter a wider bandwidth to improve the signal-to-noise ratio. Timed Events Area In the Timed Events area, you program actuation of a rear panel contact closure as a function of either time or the absorbance level from one of the discrete wavelength channels. This feature can be used to trigger an external device, such as a fraction collector. See your Surveyor PDA Plus Detector Hardware manual for information on connecting an external device to the PDA detector. The Time Events table lists all of the external events in chronological order. The type, time, channel, level, and delay for each event is included for each external event. You can add, modify, and remove events to the external events table by double-clicking the event setting you want to modify, or by using New, Delete, or Delete All buttons. In the Timed Event dialog box, which is accessed by clicking the New button or an event in the Time Events table, you select the following parameters: • Type • Time • Channel • Level • Delay The Type list describes how the event is actuated. The selections are Event Off, Event On, Zero Data, and Level Trigger. The Event Off option turns the external Event contact Off. The Event On option turns the Event On. The Level Trigger option turns the Event On when a specified absorbance level is reached. The Zero Data option performs a zeroing of the detector signal. The Event Off option is the default selection. The Time box specifies at what point in the analysis the external Event is triggered. The range is 0.00 to 600 min. The maximum allowable time is the run time. The default value is 1.00 min. 92 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the PDA Detector The Channel list designates which discrete wavelength channel is monitored for the absorbance level. Either A, B, or C can be selected. The A wavelength channel is the default selection. The Level box specifies the absorbance level at which the external Event is triggered if the Type is set to Level. The range is from -2000 to 4000.00 mAU. The default value is 0.00 mAU. The Delay box is used in conjunction with the Level box to compensate for the volume between the detector flow cell and the end of the outlet line going to a fraction collector or other instrument. The range is 0.00 to 65535.00 s. The default value is 0 s. Programming the Surveyor PDA Plus Detector To program the Surveyor PDA Plus Detector 1. Type a run time from 0 to 600 min in the Run Time box. 2. Select a rise time from 0 to 10.0 s in the Filter Rise Time list. 3. To collect spectral data, select the Spectra check box. Then, make the following entries and selections: a. Type a starting wavelength from 190 to 799 nm in the Start Wavelength box. b. Type an ending wavelength from 191 to 800 nm in the End Wavelength box. The ending wavelength must be greater than the starting wavelength. c. Type a value for the wavelength interval in the Wavelength Step box. Depending on the wavelength range defined by the starting and ending wavelengths, the allowable values are 1 to 610 nm. The wavelength range must be an integral number of wavelength steps. If you are collecting spectral data for a spectral library, use a wavelength step of 1 nm. d. Select a sample rate from the Sample Rate box. As you increase the sampling rate you also increase the data file size. e. Type a bandwidth in the Filter Bandwidth box. Depending on the wavelength range defined by the starting and ending wavelengths, the allowable values are the subset of odd integers from 1 to 49 nm. See “Filter Bandwidth” on page 90. Increasing the bandwidth decreases the spectral resolution. f. For normal data collection, select the Wavelength / Absorbance option in the Units area.

Select a sampling rate (in data points per second) from the Sample Rate list. Higher data rates for discrete channels do not add significantly to the data file size. b. For each discrete channel, type a wavelength from 190 to 800 nm in the Wavelength box and a filter bandwidth in the Filter Bandwidth box. Depending on the discrete wavelength, the acceptable bandwidth range is from 1 to 49 nm in odd-number increments with 1 nm meaning no filtering. Bandwidth values outside the range of the detector are not allowed. For example, for the discrete wavelength of 200 nm, the maximum allowable bandwidth is 21 nm. At a bandwidth setting of 21 nm, the reported absorbance value for 200 nm will be a weighted average from 190 nm to 210 nm. A value greater than 21 nm would be outside the lower range limit of the detector, which is 190 nm. 5. If you want to add a timed event to your Instrument Method, such as the triggering of a fraction collector as a peak begins to elute, do the following: a. In the Timed Events area (see Figure 57 on page 87), click New. Xcalibur displays the Timed Event dialog box shown in Figure 60. b. Select the appropriate parameters from the Timed Event dialog box.

Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 95 4 Creating Instrument Methods Entering the Method Parameters for the UV/Vis Detector Entering the Method Parameters for the UV/Vis Detector The instrument control parameters for the Surveyor UV/Vis Plus Detector are entered in the Surveyor UV/Vis Instrument Setup view shown in Figure 61. To open the Surveyor UV/Vis Plus view Click the Surveyor UV/Vis icon in the Viewbar of the Instrument Setup window. Figure 61. Surveyor UV/Vis Instrument Setup view To program the Surveyor UV/Vis Plus Detector 1. In the Rise Time list, select a rise time from 0 to 10.0 seconds Rise time is the response time of the detector, in seconds, to the signal. Increasing the rise time decreases the baseline noise; however, setting the rise time to a value greater than one-tenth the width of the chromatographic peak at half-height results in peak broadening as shown in Figure 58 on page 88. The one-second default value is appropriate for most LC applications 2. In the Data Rate list, select a data rate from 4 to 20 points per second. 96 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Entering the Method Parameters for the UV/Vis Detector 3. To zero the baseline at a specific time point, select the Enable autozero check box and type a time in the Autozero time (min) box. The detector resets its output voltage to zero at this time point. 4. In the Program type area, select one of the following options: • Select the Single wavelength 190 to 800 nm option to collect one chromatogram during a run. You can program time wavelength changes in the program table. • Select the Dual wavelength UV 190 to 450 nm option to collect two chromatograms in the UV range during a run. You can program time wavelength changes in the program table. • Select the Dual wavelength Vis 366 to 700 nm option to collect two chromatograms in the visible range during a run. You can program time wavelength changes in the program table. 5. To re-zero the baseline when a programmed wavelength change occurs, select the Zero on wavelength change check box. The detector does not zero the baseline on the first or last rows of a wavelength program. If the wavelength program contains three or more rows, the detector zeroes the baseline on the second row and all successive rows until it reaches the last row. The detector zeroes its output signal even if the same wavelength is listed in the second through second to last rows of the table. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 97 4 Creating Instrument Methods Adding a Sample Preparation Routine to the Method Adding a Sample Preparation Routine to the Method In Xcalibur, sample preparation routines are part of the Instrument Method. In the Sample Preparation page, you create a multi-task routine, which can contain up to 512 tasks. A task consists of a sample preparation operation and its associated parameters. The ability to add 512 tasks to a sample preparation routine gives you considerable flexibility, however, the arrangement of the tasks in the task list must follow a logical order. For example, you cannot add a task that deposits liquid before you add a task that draws liquid. In addition, if you are using the 250 μL concentric syringe that ships with the Surveyor Autosampler, you must follow an additional set of rules that allow for the proper positioning of the inner and outer plungers of the syringe. This section contains the following topics: • Opening the Sample Preparation Page • Building the Sample Preparation List • Sample Preparation Rules • An Example of a Sample Preparation Routine Opening the Sample Preparation Page To open the Sample Preparation page 1. Double-click the Xcalibur icon on your desktop to display the Xcalibur Home Page. 2. On the Xcalibur Home Page, click the Instrument Setup button in the Road Map or choose Goto > Instrument Setup. 3.

Enter the appropriate values for each parameter. c. Click Add To Task List. The task is copied to the Task List list in the Method area. Note If the previous task used the small bore of the syringe, you must add a Flush to Waste or a Wash Needle task before you can add a task that requires the use of the large bore of the syringe. In addition if the previous task used the small bore of the syringe, the transfer volume of the current task will be limited to the nominal syringe size or less. See “Sample Preparation Rules” on page 101 for more information. 4. Edit the task list as needed: • To remove the last task in the list, click Remove Task. • To clear the entire task list, click Clear All Tasks. 100 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Adding a Sample Preparation Routine to the Method Table 6. Sample Preparation Rules Pretreatment Tasks Task Description Deposit Liquid in Sample Deposits liquid into a designated sample vial or well. Deposit Liquid in Reservoir Deposits liquid held in the needle tubing into a reservoir vial. Draw from Sample Withdraws liquid from a sample vial or a well. Draw from Reservoir Withdraws liquid from a reservoir vial. Flush to Waste Moves the needle to the injection port and dispense a specified volume of solvent drawn from the wash bottle or a reservoir vial. Mix at Sample Mixes the contents at a sample location by aspirating the sample into the needle tubing and expunging it back into the sample location. Mix at Reservoir Mixes the contents of a reservoir vial. Mixing is accomplished by aspirating and expunging the contents of the reservoir vial. Transfer from Sample to Reservoir Moves liquid from a sample vial or well to a reservoir vial. Transfer from Sample to Sample Moves liquid from one sample vial or well to a second sample vial or well. Transfer from Reservoir to Reservoir Moves liquid from one reservoir vial to another reservoir vial. Transfer from Reservoir to Sample Moves liquid from a reservoir vial to a sample vial or well. Wait Time Pauses the sample preparation activity for a specified period of time in min Wash Needle Moves the needle to the waste station and dispense a specified volume of solvent drawn from the wash bottle or a reservoir vial. The maximum volume that can be deposited, drawn, or transferred during a sample preparation task depends on the syringe type, the task requested, and the previous step in the sample preparation method. For the 250 μL concentric syringe, the manner in which the various sample preparation tasks can be linked together is affected by whether the task takes place in only the large bore of the syringe, in only the small bore of the syringe, or in either bore of the syringe. The sample preparation tasks can be divided into three groups depending their bore usage as shown in Table 7. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 101 4 Creating Instrument Methods Adding a Sample Preparation Routine to the Method Table 7. Sample preparation tasks arranged in groups according to bore usage Small Bore Only Large Bore Only Small or Large Bore Draw from Sample Mix at Sample Draw from Reservoir Transfer from Sample to Sample Mix at Reservoir Deposit Liquid in Sample Transfer from Sample to Reservoir Wash Needle Deposit Sample in Reservoir Flush to Waste Transfer from Reservoir to Sample Transfer from Reservoir to Reservoir For the 250 μL concentric syringe, the arrangement of the tasks in the sample preparation list is restricted by the following rules: Note To save a method, it must conform to these rules. • For tasks performed with the small bore of the concentric syringe, the maximum volume (sample + air bubble) that you can draw, deposit, or transfer is limited to the nominal size of the syringe, 250 μL. If a task can be performed from either the small or the large bore, the concentric syringe uses the small bore if the requested volume (liquid + air bubble) plus any volume left in the needle tubing from a previous step is less than the nominal syringe size. • For tasks performed with the large bore of the concentric syringe, the maximum volume (sample + air bubble) that you can draw, deposit, or transfer is limited to 500 μL, except for the Wash Needle and Flush to Waste tasks. If a task can be performed from either the small or the large bore, the syringe uses the large bore if the requested volume (liquid + air bubble) is greater than the nominal syringe size. • Crossover between bores is not allowed. Therefore, you cannot add a task that uses the large syringe bore immediately following a task that uses the small syringe bore. To switch from the small bore to the large bore of the syringe, you must insert a Flush to Waste step or a Wash Needle step. These tasks home the position of the syringe plungers. 102 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 4 Creating Instrument Methods Adding a Sample Preparation Routine to the Method An Example of a Sample Preparation Routine This topic contains an example that describes how to create a sample preparation routine to dilute samples ten-fold.

This section contains the following topics: • Cell States • Cursor Actions Cell States When you open a [.raw] data file in the Qual Browser window, the information within the data file is displayed as a grid of cells. There are three hierarchal states, which are described in this section, for a cell within the grid: • Inactive Cells • Active but Unpinned Cells • Active and Pinned Cells The grid always contains either one active but unpinned cell or one pinned cell. If the grid contains more than one cell, only one cell can be active and the rest of the cells are inactive. An unpinned cell has a gray pin icon in its upper right corner. A pinned cell has a green pin icon in its upper right corner. Inactive Cells 140 Surveyor Plus Getting Started with Xcalibur Inactive cells are not highlighted with a gray border and the pin icon in their upper right corners are gray. The cell in the lower portion of Figure 91 is inactive as indicated by the absence of a gray border. Menu commands, toolbar buttons, and cursor actions do not affect inactive cells. If you want to zoom in on the contents of a cell or access its shortcut menu, you must make it an active cell. Thermo Electron Corporation 6 Using Qual Browser Working with the Cell Grid Gray Border Shortcut Menu Unpinned Active Cell Inactive Cell Figure 91. Qual Browser window, displaying an active chromatogram cell and an inactive PDA spectrum cell Active but Unpinned Cells An active but unpinned cell is highlighted with a gray border and the pin icon in its upper right corner is gray. The cell in the upper portion of Figure 91 is active but unpinned. Menu commands, toolbar buttons, and cursor actions affect the active cell. Clicking an inactive cell in the grid will make it the active cell. Active and Pinned Cells Clicking the pin in the upper right corner of a cell makes it the pinned cell within the grid. A pinned cell is an active cell that cannot be made inactive by clicking in another cell. Instead, actions performed in the inactive cells affect the pinned cell as described in the next topic, “Cursor Actions” on page 142. The lower cell in Figure 92 is a pinned cell. If you want to automatically change the range of a cell by clicking in the grid, you must pin the cell. For example, if you want to display the spectrum for the 1 min time point without opening the Spectrum Ranges dialog box, pin the Spectrum cell. Then, click the 1 min time point in the inactive chromatogram cell. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 141 6 Using Qual Browser Working with the Cell Grid Inactive Cell Pinned Cell Figure 92. Qual Browser window, displaying an inactive cell and a pinned cell Cursor Actions Within the cells of the grid, you can use the cursor in three ways: • A click picks a point on the cell. • A line dragged parallel to any axis picks a range. • A line dragged in any diagonal direction selects an area. The effect of these actions depends on the state of the cell. Within an active cell, cursor actions rescale the plot. See Table 8. Table 8. Effect of cursor action in an active cell Cursor Action Effect Drag parallel to X-axis Rescale graph showing selected X range only, same Y range Drag parallel to Y-axis Rescale graph showing selected Y range only, same X range Dragged area Rescale graph showing both the selected X and Y ranges If one of the cells is pinned, the cursor action in any of the inactive cells is applied to the pinned cell.

The peaks areas are shown above the apexes of the integrated peaks. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 167 6 Using Qual Browser Determining Peak Areas Figure 118. Avalon Peak Detection Settings page and Chromatogram view 168 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation 6 Using Qual Browser Calculating the Purity of the Chromatographic Peaks Calculating the Purity of the Chromatographic Peaks Xcalibur can calculate the spectral purity of your chromatographic peaks by comparing the similarity of the spectra across the peak to a spectrum from the peak apex. The calculation is affected by the integration of the scan chromatogram and by the scan threshold, peak coverage, and scan wavelengths that you set in the Peak Purity Settings dialog box. To display the purity values for the integrated peaks 1. Select a chromatogram for a scan wavelength as described in “Displaying Scan Chromatograms” on page 149. 2. Set the integration parameters for the chromatogram as described in “Determining Peak Areas” on page 166. 3. Right-click the chromatogram cell and choose Peak Purity to open the Peak Purity Settings dialog box. See Figure 119. Figure 119. Peak Purity Settings dialog box 4. In the Peak Purity Settings dialog box, select the Enable check box. 5. In the Scan Threshold box, type an appropriate scan threshold. The scan threshold limits the portion of the peak included in the analysis to spectral slices that have a lambda max above the scan threshold. You can set this limit to eliminate noise from the analysis. The limits for this box are 0 μAU to 2000000 μAU. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 169 6 Using Qual Browser Calculating the Purity of the Chromatographic Peaks 6. In the Peak Coverage box, type an appropriate value for your application. The limits for this parameter are 1 to 100% coverage. At a setting of 100%, Xcalibur will compare all the spectral slices that fall within the beginning and ending tick marks of the integrated peak. If you want to limit the peak purity calculation to a specific range of wavelengths in your scan, select the Limit Scan Wavelength check box, and then enter a wavelength range in the Wavelength Range box. 7. Click OK to exit the Peak Purity Settings dialog box. Then, view the effect of your peak purity settings. • Figure 120 shows the effect of the scan wavelength on peak purity. • You can see the effect of integration on peak purity by comparing Figure 121 and Figure 122. • Figure 123 shows the effect of the scan threshold setting on peak purity. • Figure 124 shows the effect of the peak coverage setting on peak purity. 225 nm scan wavelength 3 uAU scan threshold 95% peak coverage 239 nm scan wavelength 3 uAU scan threshold 95% peak coverage Figure 120.

The PDA detector is tested for linearity, noise, and drift. The LC pump is calibrated to produce an accurate flow rate while pumping water at 1 mL/min. Its ability to accurately proportion binary mobile phases is also tested at a flow rate of 1 mL/min. The column oven and the tray temperature zones of the autosampler are calibrated at 30 °C. The positioning of its XYZ arm mechanism is calibrated for the carrier trays supplied by Thermo Electron. Because of the sensitivity of its optical bench, it is best to recalibrate the Surveyor PDA Plus Detector after you install it, each time you move it, change its flow cell, or replace either of the lamps. In addition, you might need to increase or decrease the amount of incident light reaching the diode array by adjusting the attenuators. The Surveyor Autosampler Plus does not require calibration upon arrival at its shipping destination. However, if you use custom vials or custom microplates, you need to perform a Well Bottom Distance calibration, which determines the actual depth of a vial or microplate well. See “Well Bottom Distance Calibration” on page 206. If problems occur with the column oven control, the tray temperature control, or the arm positioning, contact a Thermo Electron service representative. Calibration procedures for these items are included in this appendix for users who prefer to maintain their own instruments. Like the autosampler, the Surveyor LC Pump Plus does not require calibration upon arrival at its shipping destination. However, over time, the pressure readings from its built-in pressure transducer can drift, thereby requiring re-zeroing. If you are running the LC pump at high backpressures, you might notice an increase in its pressure pulsation. You can reduce this pressure pulsation by adjusting the compressibility setting of the LC pump. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 173 A Calibration Procedures Verifying the Performance of the PDA Detector Verifying the Performance of the PDA Detector This section contains the following procedures: • Turning On the Lamps • Adjusting the Light Output • Performing a Wavelength Calibration • Performing a Dark Current Calibration Turning On the Lamps Before you perform either calibration procedure, turn on both lamps and allow the temperature of the detector to stabilize for approx. one hour.

Surveyor PDA Plus Direct Control – Configuration page Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 175 A Calibration Procedures Verifying the Performance of the PDA Detector Adjusting the Light Output The Surveyor PDA Plus Detector has two attenuators that control the light output from the lamps. During the lifetime of the Surveyor PDA Plus Detector it might be necessary to adjust the attenuators to increase or decrease the amount of light falling onto the array. Decreasing light output to the array increases baseline noise. Increasing light output to the array can cause saturation of the diode array. If the array is saturated the response from the Surveyor PDA Plus Detector will be a flat baseline. The attenuators require adjustment when either lamp is replaced or when the flowcell is replaced. The first time that you adjust the attenuators, you need to create an [.spda] method. After you create the method for adjusting the attenuators, save it with a name that you will associate with adjusting the attenuators and store it for future use. Saving the method will simplify future adjustments of the attenuators. Note Before you adjust the attenuators, replace the column with a flow restrictor, and set the pump to deliver HPLC-grade water at a flow rate of 1 mL/min through the flowcell. To adjust the light output from the lamps, perform the following procedures in the order listed: 1. Preparing the LC for an Adjustment of the Attenuators 2. Accessing the Attenuators 3. Adjusting the Attenuators Preparing the LC for an Adjustment of the Attenuators To prepare your LC system for an adjustment of the attenuators 1. Ensure that the lamps are On: a.

Wavelength Calibration wizard – page 8 190 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Calibration Procedures Verifying the Performance of the PDA Detector Performing a Dark Current Calibration The function of the array calibration is to measure and correct for the dark current produced by the diodes of the photodiode array. The dark current is the small amount of background signal that is produced by the diodes of the array even when both lamps are turned off. Typical dark current values range from 1500 to 3000 counts. The environmental conditions of your laboratory can cause the dark current of the diode array to increase over time. Therefore, we recommend that you perform an array calibration (dark current) after any of the following events occurs: • After 100 hours of use or monthly, whichever comes first • Whenever a significant temperature change occurs • After you move the detector • After you replace the lamp • After you download a new firmware file Because the dark current produced by the diodes rises as the temperature within the detector rises, it is important to warm up the lamps for 1 hour before you perform a dark current calibration. Warming up the lamps for 1 hour equilibrates the detector to its normal operating temperature. Xcalibur briefly turns the lamps off as it performs the dark current calibration routine. After it completes the dark current calibration routine, Xcalibur turns the lamps back on. To perform the dark current calibration 1. Pump methanol through the flow cell at 1 mL/min. 2. Turn On both lamps and wait 1 hour for the lamps to equilibrate. 3. From the menu bar of the Surveyor PDA Plus Instrument Setup window, choose Surveyor PDA Plus > Direct Control.

Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 205 A Calibration Procedures Calibrating the Autosampler Well Bottom Distance Calibration The Well Bottom Distance wizard is used to calibrate the distance that the needle must travel to reach the bottom of a vial or well. The XYZ arm uses this value when you select one of the custom tray configurations. The well bottom distance wizard consists of two dialog boxes: The Select Calibration Method dialog box and the Well Bottom Distance dialog box. Note Because the autosampler stores only one value for the custom well bottom distance, you must perform a well bottom distance calibration each time you select a new custom tray type configuration and each time you use a different type of custom vial or custom microtitre plate. To perform a well bottom distance calibration 1. Open the Well Bottom Distance Calibration Wizard: a. If the Information View is closed, click the Information View button to open it.

Click Finish to exit. 208 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Calibration Procedures Calibrating the Autosampler Figure 160. Well Bottom Distance wizard – Manual Calibration IMPORTANT Remove vial caps or microtitre plate lids before performing an active well bottom distance calibration. As the needle pierces a vial cap or a microtitre plate lid, the spring in the needle mechanism is compressed, which can cause premature activation of the needle sensor. IMPORTANT Before placing a custom tray into the tray compartment of the autosampler, check the height limitations for microplates and high-density micro plates listed in the hardware manual for your autosampler. Tall objects will stall the autosampler arm. 4. If you selected the Calibrate To Find Value option button on the Select Calibration Method page of the wizard, you can perform an active calibration using the Well Bottom Distance dialog box shown in Figure 161: a. Remove the cap or lid from your vial or microtitre plate. b. Place the vial into a tray or the microtitre plate into a carrier, and then place the tray or carrier into the tray compartment of the autosampler. c. Type a vial or well location in the Calibrate At Well Position text box. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 209 A Calibration Procedures Calibrating the Autosampler Note If you are calibrating the bottom distance of a vial, verify that you have placed a vial in the selected location. d. Click Set Calibration to activate the autosampler. After the autosampler arm moves to the selected location, the needle mechanism descends until it detects the bottom of the vial or well. After it detects the bottom, the autosampler arm moves to the home position, and the software program displays the new bottom distance calibration value at the top of the dialog box. 5. Click Finish to accept the calibration. Figure 161. Well Bottom Distance Calibration wizard – Active Calibration 210 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Calibrating the LC Pump Calibration Procedures Calibrating the LC Pump There are two calibration options for the Surveyor LC Pump that affect its performance. These are the alpha setting, which affects the flow rate, and the compressibility setting, which affects the pressure pulsation of the system. The compressibility setting is set to that for water, and then the alpha setting is factory calibrated to produce an accurate flow rate for water. If you are pumping solvents other than water and your application is sensitive to pressure pulsation, you might want to optimize the compressibility setting. Changing the compressibility setting affects the accuracy of the flow rate. Therefore, after you optimize the compressibility setting to minimize the pressure pulsation of your system, you will want to check the accuracy of the flow rate. If adjusting the compressibility setting has affected the accuracy of your flow rate, you will want to adjust the alpha setting of the LC pump. In addition to the alpha setting and the compressibility setting, the pressure transducer that is attached to the back of the purge manifold assembly is also factory calibrated. If you replace the pressure transducer, you will need to update the pressure sensor adjustment setting. Even if you never need to replace the pressure sensor, its readout tends to drift under normal usage. Therefore, you need to occasionally re-zero its output. This section contains the following topics: • Accessing the Calibration Options for the LC Pump • Calibration Options • Calibration Procedures Accessing the Calibration Options for the LC Pump You can fine-tune the performance of the Surveyor LC Pump from the Calibration - Surveyor LC Pump Direct Control dialog box.

From the Surveyor LC Pump view, choose Surveyor LC Pump > Direct Control > Calibration to open the Calibration – Surveyor LC Pump Direct Control dialog box shown in Figure 162. Figure 162. Calibration page for the Surveyor LC Pump Calibration Options The Xcalibur data system provides the following calibration options (see Figure 162) for the Surveyor LC Pump Plus. These options are described in this topic. • Compressibility • Pressure Recorder Full Scale • Flow Rate Adjustment (Alpha) • Pressure Sensor Adjustment • Pressure Transducer Zero 212 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Compressibility Calibration Procedures Calibrating the LC Pump The compressibility of a liquid is a measure of its resistance to a decrease in volume caused by an increase in pressure. Compared to gases, most liquids are relatively incompressible. Water, a commonly used mobile phase solvent, is even less compressible than most organic solvents because of its extensive hydrogen bonding and cluster structure. Effect of the Compressibility Setting Even though liquids are relatively incompressible, the compressibility of your mobile phase can affect your chromatography if you are running the LC pump at the upper limit of its pressure range. You can use the compressibility setting for the Surveyor LC Pump to compensate for the compressibility of your mobile phase. However, changing the compressibility setting simultaneously affects both the pressure pulsation of the Surveyor LC Pump and the flow rate of the mobile phase. The compressibility effect is caused by the portion of the cam cycle in which the pistons are compressing the mobile phase. The compressibility portion of the cam cycle extends from the time at which the primary piston starts discharging until the time at which the secondary piston reaches full intake—approximately 80° of the cam cycle. To minimize the pressure pulsation and maintain a constant flow rate, the on-board CPU compensates for this compression by making fine adjustments to the speed of the stepping motor. If the compressibility setting is incorrect, the LC pump will not be able to effectively minimize the pressure pulsation. Figure 163 shows the effect of the compressibility setting on the pressure pulsation. The pressure trace was recorded as water was pumped at a flow rate of 3 mL/min. Three runs were recorded and the compressibility setting was changed between the runs. The compressibility settings for the three runs were 0.45 GPa-1, 1.25 GPa-1, and 3.0 GPa-1. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 213 A Calibration Procedures Calibrating the LC Pump Figure 163. Overlaid LC pump pressure traces, showing the effect of the compressibility setting Table 10 shows a comparison of water pumped at three different compressibility settings. The correct compressibility setting for water is 0.45 GPa-1. The pressure pulsation as well as the actual flow rate increased as the compressibility setting increased. Table 10. Measured flow rate and pressure pulsation vs. compressibility setting Compressibility Setting %Pressure Pulsation Actual Flow Rate (mL/min) % Rel Diff 0.45 GPa-1 ± 0.2% 3.01 + 0.3% 1.25 GPa-1 ± 0.4% 3.05 + 1.8% ± 1% 3.18 + 5.9% 3.0 GPa -1 Compressibility Ratios for Common Solvents Most mobile phases are made up of a mixture of solvents. Therefore, you need to determine the correct compressibility setting for a given mobile phase empirically. Table 11 lists the compressibility ratios for a few common solvents. 214 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Calibration Procedures Calibrating the LC Pump Table 11. Compressibility ratios for common solvents Pressure Recorder Full Scale Solvent Compressibility Ratio (GPa-1) Water 0.45 Acetonitrile 1.20 Methanol 1.25 Hexane 1.60 The pressure recorder full-scale calibration option sets the scaling factor for the pressure trace if you choose to monitor the pressure with a chart recorder. The pressure recorder terminals are located on the back of the Surveyor LC Pump. See Figure 164. Integer values from 1 to 10 are within the allowable range. Full scale = Set value × 4.9 MPa (50 kgf/cm2) (full scale voltage = 1 mV) For example: When the set value = 1, the full scale is 4.9 MPa (50 kgf/cm2) When the set value = 10, the full scale is 49.0 MPa (500 kgf/cm2) 4.9 MPa = 50 kgf/cm2 = 49 bar = 711 psi Note The value for the scaling factor is stored until you change it or until you turn off the power to the Surveyor LC Pump.

Terminals located on the back of the Surveyor LC Pump Plus Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 215 A Calibration Procedures Calibrating the LC Pump Flow Rate Adjustment (Alpha) The alpha value for your Surveyor LC Pump Plus is factory calibrated based on a flow rate of 1.000 mL/min for distilled water. A sticker containing the factory calibration value is located inside the pump on the motor casing. You can optimize the alpha value for your application by updating the alpha setting. The allowable range for alpha values is 1 to 9.9. If you are pumping water, decreasing the alpha value by 1, decreases the flow rate by 1%. Whereas, increasing the alpha value by 1, increases the flow rate by 1%. Pressure Sensor Adjustment Reset the Pressure Sensor Adjustment parameter when the pressure sensor is replaced. Each pressure sensor is labeled with a data sticker that contains a “0.XXXX” value for the pressure sensor adjustment setting. Multiply this value by 10000 and then update the pressure sensor adjustment setting for your Surveyor LC Pump Plus. Pressure Transducer Zero The pressure readout for the Surveyor LC Pump Plus is produced by a cell type potentiometer. This type of device tends to drift by small increments. Therefore, you will occasionally need to re-zero the readout. To update the pressure transducer zero value, turn off the pump flow and open the drain valve knob before clicking the pressure transducer zero button in the software program that operates your pump. Calibration Procedures You fine-tune the performance of the Surveyor LC Pump Plus from the Calibration - Surveyor LC Pump Direct Control dialog box (Figure 162 on page 212). For instructions on accessing this dialog box, see “Accessing the Calibration Options for the LC Pump” on page 211. This topic contains the following calibration procedures for fine-tuning the performance of the Surveyor LC Pump Plus: • Updating the Compressibility Setting • Optimizing the Compressibility Setting • Scaling the Output of the Pressure Recorder Terminals • Updating the Flow Rate Adjustment Setting • Updating the Pressure Sensor Adjustment Setting • Re-zeroing the Pressure Transducer Updating the Compressibility Setting 216 Surveyor Plus Getting Started with Xcalibur If you have already determined the best compressibility setting for your application, update the compressibility setting of the Surveyor LC Pump Plus. Thermo Electron Corporation A Calibration Procedures Calibrating the LC Pump To update the compressibility setting 1. Open the Calibration page for the Surveyor LC Pump as described in “Accessing the Calibration Options for the LC Pump” on page 211. 2. Type a new value into the Compressibility setting box. Then click Set. Optimizing the Compressibility Setting To optimize the compressibility setting for you application 1. Set up your system: a. Set up a device to record the pressure output from the back panel pressure terminals. See “Pressure Recorder Full Scale” on page 215. b. Scale the output of the pressure terminals as described in “Scaling the Output of the Pressure Recorder Terminals” on page 219. 2. Download the mobile phase parameters specified in your application: a. If it is not already on, turn on the power to the Surveyor LC Pump Plus. b. Open the Instrument Setup - Surveyor LC Pump view as described in step 2 on page 211. c. From the Surveyor LC Pump view, choose Surveyor LC Pump > Direct Control > Operation to open the Operation - Surveyor LC Pump Direct Control dialog box shown in Figure 165. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 217 A Calibration Procedures Calibrating the LC Pump Figure 165. Surveyor LC Pump – Direct Control – Operation page d. In the Method area, enter the specified flow rate in the Flow Rate box and enter the specified mobile phase composition in the Component A through Component D boxes e. Click Download to send these parameters to the on-board CPU of the Surveyor LC Pump. f. Click Pump On to turn on the pump flow. 3. Record the pressure trace. 4. If the pressure pulsation is too high for your application, change the compressibility setting. Then, repeat steps 2 and 3. Continue to change the compressibility setting until the level of pump pulsation is adequate for your application. Note Changing the compressibility setting will affect the flow rate. 5. After you change the compressibility setting to minimize the pressure pulsation, check the flow rate. If necessary, adjust the flow rate adjustment setting as described in “Updating the Flow Rate Adjustment Setting” on page 219. 218 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Scaling the Output of the Pressure Recorder Terminals Calibration Procedures Calibrating the LC Pump To set the full-scale output of the pressure recorder terminals 1. Open the Calibration page for the Surveyor LC Pump Plus as described in “Accessing the Calibration Options for the LC Pump” on page 211. 2. Enter a value from 1 to 10 in the Pressure Recorder Full-Scale box (Figure 162 on page 212). Then, click Set. For information on scaling the output of the pressure recorder terminals, see “Pressure Recorder Full Scale” on page 215. Updating the Flow Rate Adjustment Setting If you change the compressibility setting for the Surveyor LC Pump, you might also need to change its flow rate adjustment setting. Changing the flow rate adjustment setting can compensate for minor deviations in the flow rate of approximately ±5% from the expected value. To update the flow rate adjustment setting 1. Open the Calibration page for the Surveyor LC Pump as described in “Accessing the Calibration Options for the LC Pump” on page 211. 2. Enter a new value in the Flow Rate Adjustment (alpha) box (see Figure 162 on page 212): • If the actual flow rate is below the set value, increase the alpha value. If you are pumping water, increasing the alpha value by 1, increases the flow rate by 1%. For example, if the pump is set to deliver a flow rate of 1 mL/min and the actual flow rate is 0.96 mL/min, which is 4% below the set rate, raise the current setting by 4. If the current setting is 5.0, enter a new setting of 9.0. • If the actual flow rate is above the set value, decrease the alpha value. If you are pumping water, decreasing the alpha value by 1, decreases the flow rate by 1%. For example, if the pump is set to deliver a flow rate of 1 mL/min and the actual flow rate is 1.04 mL/min, which is 4% above the set rate, lower the current setting by 4. If the current setting is 5.0, enter a new setting of 1.0. 3. Click Set. Thermo Electron Corporation Surveyor Plus Getting Started with Xcalibur 219 A Calibration Procedures Calibrating the LC Pump Updating the Pressure Sensor Adjustment Setting Reset this parameter when the pressure sensor is replaced. Each pressure sensor is labeled with a data sticker that contains a “0.XXXX” value for the pressure sensor adjustment setting. Multiply this value by 10,000 and enter the result in the Pressure Sensor Adjustment setting box. To update the pressure sensor adjustment setting 1. Open the Calibration page for the Surveyor LC Pump as described in “Accessing the Calibration Options for the LC Pump” on page 211. 2. Enter the value on the data sticker “0.XXXX” multiplied by 10000 in the Pressure Sensor Adjustment setting box (see Figure 162 on page 212). 3. Click Set. Re-zeroing the Pressure Transducer The offset error of the pressure transducer is the value that is displayed when it should be zero, such as when the purge manifold knob is set to the open position. You can correct for this offset error by re-zeroing the pressure readout of the pressure transducer when the purge manifold knob is open. To re-zero the output of the pressure transducer 1. Stop the flow of solvent from the LC pump: a. From the Instrument Setup window, choose Surveyor LC Pump > Direct Control > Operation. b. Click Pump Off. 2. Open the drain valve to ensure that the transducer is actually sensing zero system pressure. See Figure 166. 220 Surveyor Plus Getting Started with Xcalibur Thermo Electron Corporation A Open Calibration Procedures Calibrating the LC Pump Closed Figure 166. Drain valve in open and closed positions 3. Open the Calibration page of the Direct Control dialog box by choosing Surveyor LC Pump > Direct Control > Calibration. 4. Click Zero in the Pressure Transducer area (see Figure 162 on page 212). 5. When you are finished zeroing the pressure transducer, close the drain valve by turning the knob clockwise until you feel resistance. Note Applying excessive force to the drain valve knob reduces the life span of its O-ring.
