Tip Use the Lamp Startup Time feature to preserve the useful lifetime of the deuterium
lamp. The default lamp startup time for the PDA detector is 4:55 PM. For optimal system
performance, reset the lamp startup time to approximately two hours before you plan to
start data acquisition. For information about changing the lamp startup time, see “Setting
the Lamp Startup Time” on page 166.
Tip The default setting for the autosampler maintenance counters is 0. If you turn on the
autosampler maintenance log (see “Communication Page” on page 52) when you specify
the configuration settings for the autosampler and leave the counters at the default setting,
the autosampler status displays Maintenance Due and the data system prevents you from
starting a run. For information about changing the counter settings on the Maintenance
Information page, see “Autosampler Maintenance Information” on page 309.

Introduction to the Surveyor Plus LC System
The Surveyor Plus high-performance liquid chromatography system (see Figure 1), which
integrates with the Thermo Scientific family of mass spectrometers, consists of an analytical
pump, an autosampler, an optional PDA detector or UV/Vis detector, and a solvent platform.

Introduction to the Surveyor Plus LC System
Analytical Pump
Analytical Pump
Thermo Scientific, part of Thermo Fisher Scientific Inc., offers two analytical pumps in the
Surveyor Plus product line: 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 required
to purge the lines when you replace an eluent.
These topics describe the features of the Surveyor analytical pumps:
• 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
1 to 2000 μL/min, which is the range needed to perform LC and LC/MS applications. You
can run precise gradients from 200 to 2000 μL/min, while the extremely low gradient delay
volume of 65 μL ensures minimum system cycle times.
The pulse dampening assembly consists of a low volume T-connector that the mobile phase
passes through. Attached to the side leg of the T-connector is a 2 mL loop of stainless steel
tubing. The loop terminates with a priming valve (pulse dampener flush valve). When the
priming valve is open, you can flush or fill the dampening loop with an appropriate solvent
such as methanol or isopropanol. When the priming valve is closed, the loop is shut off from
the flow path and absorbs pump pulsations. Because the 2 mL loop is shut off from the flow
path, it adds no gradient delay volume to the LC system.
The priming solvent in the loop does not interfere with the purity of the mobile phase, and its
composition does not need to match the mobile phase.
The data system remotely controls the pump with an RS-232 communication link from the
data system computer. The only manual control is the power switch located on the front of
the pump in the lower-left corner below the door.

Introduction to the Surveyor Plus LC System
Analytical Pump
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, which is the range 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). The Xcalibur™ data system controls the pump
through an Ethernet communication link with the data system computer. The only manual
controls are the power switch located on the front of the pump in the lower-left corner below
the door and the drain valve.
The Surveyor LC Pump Plus 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 (see Figure 2). The pulse dampening assembly adds 400 μL of
gradient delay volume to the system. The Surveyor LC Pump Plus has status LEDs on the
front door and a low-voltage power supply.

Introduction to the Surveyor Plus LC System
Analytical Pump
You can use the Purge command from the data system to draw solvent at a rate of 10 mL/min
through the solvent lines connected to the pump after you open the purge valve. To open the
purge valve, turn the knob on the front of the purge manifold assembly counterclockwise
(see Figure 3). When the valve is in the open position, look for the word DRAIN to appear
upside down on the knob.

Figure 3.
Figure 4 shows the line body fitting removed from the top of the purge manifold assembly.
The line body fitting contains an inline 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 filter frit becomes clogged, the system backpressure rises.
Replace this filter frit when the system backpressure rises above its typical operating limits.

Introduction to the Surveyor Plus LC System
Autosampler
Autosampler
Thermo Fisher Scientific offers two autosampler models in the Surveyor Plus product line:
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 a temperature
controlled tray/sample compartment (0 to 60 °C). Both models let you inject samples and
perform sample preparation tasks automatically.
Note To convert from °C to °F, use the following equation:
°F = (1.8 × °C) + 32
For more information about the autosampler, see these topics:
• Tray Compartment
• Vial and Well Notation
• Injection System
• Injection Modes
• Temperature Control
Tray Compartment
The tray compartment (see Figure 5) can hold up to five conventional sample trays or one
carrier that holds three microwell plates. The tray compartment also holds up to four 16 mL
capacity reservoir vials that you can use to hold solvent, reagent, or diluent. The reservoir vials
are located behind the wash station and are designated RV1, RV2, RV3, and RV4.

Introduction to the Surveyor Plus LC System
Autosampler
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.
When you configure the autosampler (from the data system) to verify whether the tray
compartment door is open or closed, the XYZ arm automatically moves to the back of the
tray compartment when you open the door, allowing you to remove trays or replace vials.
Opening the tray compartment 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
current injection is complete. The programmed sequence of injections then halts. When you
close the tray compartment door, the sequence resumes.
Vial and Well Notation
You specify the vial or microplate well location where you want the autosampler to withdraw
sample in the sequence table or the Inject Sample direct command. You also specify the vial or
microplate well locations for sample preparation tasks.
These topics describe the notation for specifying vial and well locations:
• Vial Notation
• 96-Well Microplate Notation
• 384-Well Microplate Notation
Vial Notation
The notation for the location of vials is as follows:
Tray location in tray compartment:Vial location in tray
Where:
Tray location in tray compartment = A, B, C, D, or E
Vial location in tray = 1 through 40
A colon separates the tray location in the tray compartment from the vial location in the tray.
Figure 6 shows the tray locations.

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
Syringe Drive Assembly and Syringe Valve
The syringe drive assembly holds the autosampler syringe. There are three holes with
grommets on the back of the syringe drive assembly. You mount the syringe drive assembly to
the front of the autosampler by matching these holes to one vertical mounting pin and two
horizontal mounting pins located in front of the autosampler injection port. The rubber
grommets minimize the effects of vibration, but also cause the connection between the syringe
drive assembly and the body of the autosampler to feel slack (see Figure 10).

Introduction to the Surveyor Plus LC System
Autosampler
The syringe valve is a two-position rotary valve. In the wash bottle position, the syringe draws
wash solvent into its syringe barrel as its plunger descends. In the needle position, the syringe
draws sample solution into the needle tubing as its plunger descends and pushes sample
solution out of the needle tubing as its plunger ascends. The syringe never draws sample
solution into its barrel.
Note The needle tubing holds approximately 560 μL of solvent. If you installed the
2500 μL standard syringe (which must be special ordered) and you plan to make large
volume injections, install the 1 mL needle tubing extension that comes with this syringe.
Wash Bottle Reservoir and Tubing
The wash bottle rests in the solvent platform on the top of the LC stack. 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 fill with
air. If the syringe runs dry, the autosampler cannot draw sample into the needle tubing.
Figure 11 shows the syringe valve in the wash bottle position.

Introduction to the Surveyor Plus LC System
Autosampler
Interchangeable Syringe
The standard configuration for the autosampler consists of a 250 μL dual-concentric syringe.
The dual-concentric syringe consists of a small, inner plunger, and a larger, outer plunger
(see Figure 12).
Figure 12. Dual-concentric syringe
Inner plunger
Outer plunger
The syringe uses its inner plunger to draw and deliver sample amounts equal to or less than its
maximum capacity, which is 265 μL for the 250 μL concentric syringe. The syringe uses its
outer plunger to draw and expel large volumes of solvent, for example, during a flush or wash
cycle.
Dual-concentric syringes are available in 100, 250, and 500 μL sizes. The volume of the outer
plunger region, 565 μL, is the same for all three dual-concentric syringes. The size of the inner
plunger and the injection mode determine the available injection volume range. In addition
to offering three sizes of concentric syringes, Thermo Scientific also offers a 2500 μL standard
(single plunger) syringe.
XYZ Arm Mechanism
The XYZ arm mechanism moves the needle along the x-y plane to the requested vial or well
location. After it positions the needle above the vial or well, the XYZ arm mechanism lowers
the needle along the z axis to the requested needle height.
Figure 13 shows the needle descending to a depth of 2 mm from the bottom of a standard
1.8 mL vial.

Sample
After the autosampler withdraws the sample from the sample vial or well into the needle
tubing, the XYZ arm mechanism moves along the x-y plane, back to the home position,
which is above the injection port of autosampler, and then lowers the needle into the injection
port where it expels the sample. The sample travels through transfer tubing and into the
sample loop of the injection valve.
IMPORTANT Because the XYZ arm moves to the sample position to withdraw sample,
do not place objects taller than 1.8 inches into the tray compartment, as they will stall the
XYZ arm.
Do not move the XYZ arm manually. Instead, use the following commands and options
provided by the data system to control the position of the XYZ arm:
• To make the XYZ arm automatically move to the back of the tray compartment when you
open the tray door, select the Verify Door is Closed option, which is available when you
configure the autosampler device driver (see “Communication Page” on page 52).
• To move the XYZ arm to the back of the tray compartment, use the Position Arm to
Access Tray direct command (see “Removing and Installing Sample Trays” on page 199).
• To move the XYZ arm mechanism to its home position above the injection port, use the
Set Arm to Home Position direct command.
• To move the XYZ arm mechanism to the middle front of the tray compartment, allowing
easy access to the needle, use the Remove Needle direct command.

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. The needle fits into the needle
mount on the XYZ arm.
The needle tube assembly connects the solvent path between the needle and the syringe valve
and consists of low-pressure tubing, an internally threaded fitting that connects to the needle
assembly fitting, a sleeve, a black or red PVC cap, a needle tube guide that attaches to the
x-axis positioning frame, and an externally threaded fitting with a flangeless ferrule that
connects to the right side of the syringe valve.
IMPORTANT To prevent damage to the needle tubing, take care when you connect the
needle tubing guide to the back of the syringe drive assembly. Pinched tubing causes
performance problems.

Injection Valve and Sample Loop
The injection valve is a two-position, six-port 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 ports 1 and 4 of the injection valve. The autosampler comes with a
25 μL sample loop.
There are two positions for the six-port injection valve: fill and inject.
In the fill position (see Figure 17), the sample loop is isolated from the mobile phase stream.
As the mobile phase bypasses the sample loop, the upward movement of the autosampler
syringe plunger pushes sample into the front of the sample loop, connected to port 1 of the
injection valve. Once the sample loop is filled, excess solution exits the injection valve through
port 3 to waste.

In the inject position (see Figure 18), mobile phase enters the sample loop from the back,
backflushing the contents of the sample 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.

Introduction to the Surveyor Plus LC System
Autosampler
Injection Modes
The autosampler 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 on 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.
Approximately 0.25 μL of the sample is lost as it travels from the injection port, through the
transfer tubing, and into the injection valve. Because of this loss, the minimum recommended
injection volume is 1.0 μL.
The quantity of lost sample depends on the syringe rate. Decreasing the syringe rate decreases
the sample loss. For best results, use a syringe rate no greater than 4 μL/s for the no waste
injection mode.
IMPORTANT
For no waste injections, do the following:
• Use a sample loop that is at least 5 μL larger than the injection volume. Because the
accuracy of the nominal size is ±20%, use an estimate of 80% for the actual size. For
example, use 20 μL as an estimate for the actual volume of a 25 μL loop, and inject no
more than 15 μL with this loop size.
• Consider matching the chemistry of the sample matrix, the flush solution, and the
mobile phase. For no waste injections, the autosampler loads approximately 2 μL of
flush solvent and 3 μL of air into the sample loop, regardless of the requested injection
volume.
• Inject at least 1.0 μL of sample.
Thermo Scientific
Surveyor Plus User Guide for LC Devices

Introduction to the Surveyor Plus LC System
Autosampler
Partial Loop Injection Mode
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.
IMPORTANT To make precise partial loop injections, use a sample loop that is at least
twice the size of the injection volume. The accuracy of the nominal sample loop volume
is ±20%. Because the actual volume of the 25 μL sample loop (provided with the
autosampler) is anywhere from 20 to 30 μL, limit the maximum injection volume with
this loop to 10 μL. To inject more sample, use a larger sample loop.
Full Loop Injection Mode
The full loop injection mode is a technique that withdraws a sample volume from the vial
sufficient to overfill the sample loop by a minimum factor of two. Because the physical size of
the sample loop determines the actual injection volume, 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.
To change the injection volume, you must change the sample loop size.
Note 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:
Amtw = 3 × Vinj + Vdead + 7.5 μL
Where:
Amtw = sample volume withdrawn by the autosampler
Vinj = user-specified injection volume
Vdead = dead volume held by the transfer tubing, injection port, and rotor slot
This equation is valid until the syringe reaches its maximum capacity, when 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
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.
Column Oven Control
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.
CAUTION The column oven can reach temperatures as high as 95 °C (203 °F).
To prevent personal injury, before installing the LC column or connecting the pump to
the autosampler, make sure that the column oven compartment is at room temperature.
Between the analytical pump and the autosampler injection valve, the mobile phase is diverted
through a heat exchanger located behind the column oven. As it passes through the heat
exchanger, the mobile phase equilibrates to the temperature of the column oven before it
reaches the injection valve. The heat exchanger adds only 3 μL of gradient delay volume to the
LC system.
Detector
The Surveyor Plus product line includes two detectors that you can control from your
Thermo Scientific data system: a PDA detector and a UV/Vis detector. The PDA detector, in
combination with the 5 or 1 cm LightPipe flowcell, provides the highest level of sensitivity
available in photodiode array detection for HPLC. The UV/Vis detector can monitor two
wavelength channels. Both detectors have a dual-lamp optical bench that covers the
UV-visible spectrum from 190 to 800 nm.

Introduction to the Surveyor Plus LC System
Detector
PDA Detector
The PDA detector is a full-featured, time-programmable, photodiode array detector that can
scan the full ultraviolet-visible range from 190 to 800 nm. The detector can acquire data at a
rate of up to 20 Hz with a 20 bit digital conversion.
The optimal location for the PDA detector is above the autosampler and below the solvent
platform. The data system computer controls the PDA detector through an Ethernet
communication link. 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 light-emitting diodes (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). The light emitted by the two lamps overlaps in
the 300 to 500 nm range. A pair of attenuators that you can manually adjust controls
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 (see Figure 19). 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. Use
position 1 (Open), which places a clear, quartz window in the optical path, for normal
operation. Use position 2 (Holmium Oxide), which places a sealed, quartz cuvette filled with
a holmium oxide/perchloric acid solution (NIST™ traceable) in the optical path, for
wavelength accuracy verification and calibration.

Introduction to the Surveyor Plus LC System
Solvent Platform
The PDA detector does not have independent controls, such as a keypad, to create data
acquisition methods. Instead, you create instrument methods for data acquisition with the
data system. The only manual controls for the PDA detector are the On/Off switch that
controls line power, the attenuators that control the light throughput to the diode array, and
the holmium oxide wheel that controls the position of the wavelength calibration solution.
UV/Vis Detector
The UV/Vis detector is a full-featured, time-programmable, variable-wavelength UV/Vis
(ultraviolet/visible) absorbance detector. It operates in either the single wavelength mode, the
dual wavelength UV wavelength mode, or the dual wavelength Visible mode. The wavelength
range in the single wavelength mode is 190 to 800 nm. In the dual wavelength UV mode, the
range is 190 to 450 nm and in the dual wavelength Visible mode, the range is 366 to 700 nm.
The wavelength time table is available in all three modes. The time table can contain up to
10 lines. If you enable the Zero On Wavelength Change feature, the baseline absorbance
returns to zero between each line in the time table, even if the wavelengths remain the same.
The baseline absorbance does not return to zero 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 to 365 nm) and a tungsten lamp for the visible range
(366 to 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.
To control the UV/Vis Detector, you must first add the detector to the software instrument
configuration (see “Adding Devices to the Instrument Configuration” on page 44).
After you add the UV/Vis detector to the instrument configuration, you can set up the data
acquisition parameters from the UV/Vis detector view of the Thermo Xcalibur Instrument
Setup window (see “UV-Vis Detector Instrument Method Parameters” on page 106).
You can turn the detector lamps on or off and zero the detector output from the Direct
Control dialog box (see “UV-Vis Detector Direct Controls” on page 183).
Solvent Platform
The solvent platform, located on the top of the LC stack, holds four 1 liter solvent reservoir
bottles and one 1 liter 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 two-position syringe valve of the autosampler.

Introduction to the Surveyor Plus LC System
Status LEDs
During a run, the system issues the following sequence of run control signals:
1. The data system computer issues a request to perform an injection.
2. When the autosampler becomes ready, it issues the A/S Ready signal.
The autosampler goes into the Ready state when all the configuration and instrument
method conditions are met, including the closing of the tray compartment door, and the
sample tray and column oven temperature zone readings showing they are within
tolerance of their setpoints.
3. When the pump pressure stabilizes, the pump issues the Pump Ready signal to the
autosampler.
The autosampler injection valve switches to the fill position, and then the autosampler
pushes 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.
6. The autosampler injection valve switches to the inject position, allowing the mobile phase
to backflush the contents of the sample loop onto the column. The autosampler then
issues a momentary Inject Out signal to the detector.
7. The detector starts acquiring data.
Status LEDs
Each of the Surveyor Plus LC devices has a panel of four status LEDs located on the front of
the left door. All of the devices have these three LEDs: Power, Comm, and Run. In addition,
the detector has a Lamps LED; the autosampler has a Temp LED; and the analytical pump
has a Degas LED.
These topics describe the meanings of the LED states:
• Surveyor MS Pump Plus LED States

6. (Optional) To prevent the autosampler from making an injection when the tray
compartment door is open, select the Verify Door Is Closed check box.
When the Verify Door Is Closed check box is selected, the autosampler cannot trigger a
run when the tray compartment door is open. If the tray door is opened during a
sequence run, the XYZ arm moves to the back of the tray compartment at the end of the
current run, and the Xcalibur sequence halts.
7. (Optional) To activate the maintenance log, select the Enable Maintenance Log check
box.
The maintenance log keeps an internal count of the total injections, total valve cycles,
total needle usage, and total syringe cycles. When any of the counters exceed the user set
scheduled maintenance time (SMT), the autosampler cannot trigger a run until you
perform the scheduled maintenance or you clear the check box.
8. In the Vial Bottom Sensing area, select the type of vial bottom sensing that is appropriate
for your application:
• To activate vial bottom sensing for every injection in a sequence, select the On
option.
• To activate vial bottom sensing for only the first injection in a sequence, select the
Auto option.
• To deactivate vial bottom sensing, select the Off option.
Each tray type has a stored value for the distance that the needle must travel to reach the
bottom of the vial or well. When you activate vial bottom sensing, the autosampler
performs a search routine to determine the actual location of the vial or well bottom. If
the search routine determines a new value for the bottom distance, it is stored until you
modify the tray type. If you do not want the needle to touch the bottom of a vial or well,
deactivate vial bottom sensing.
9. In the Dead Volume (μL) box, type the value specified on the label attached to the
transfer tube assembly.
Tip When you use the No Waste injection mode, for best results, calibrate the transfer
tube volume, and then type the empirically determined value in the Dead Volume
box. To calibrate the transfer tube volume, refer to the hardware manual for the
autosampler.
10. In the Sample Loop Volume (μL) box, type the nominal size of the sample loop attached
to the injection valve.
The autosampler ships with a 25 μL sample loop.

An appropriate minimum pressure setting 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 quickly ruins the piston seals. Select a value that
is well below the typical operating pressure for your application. In the event that the
pressure falls below this limit for more than one minute, the pump automatically
stops and sends an error message to the computer.
The range is 0 to 400 bar (5800 psi) with a default value of 0 bar.
g. In the Max Pressure (bar) box, type or select the maximum operating pressure for the
pump.
An appropriate maximum pressure setting 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. Select a
value that is well above the typical operating pressure for your application, but also
below the pressure that can damage your system. If the pressure rises above this limit,
the pump automatically stops and sends an error message to the computer.
The range is 0 to 400 bar (5800 psi) with a default value of 400 bar.
h. In the Pressure Stability (bar) box, type or select an appropriate pressure stability
value from 1 to 100.
The MS pump sends a Ready signal when the system pressure reaches this limit. A
lower value requires greater pressure stability before the pump becomes ready. A
higher value is more forgiving of pressure pulsations.

this level for more than one minute, the data system triggers turns off the mobile phase flow.
Default: 0 bar
Max pressure
Specifies the maximum operating pressure of the pump. If the system backpressure rises
above this level for more than one minute, the data system triggers the pump to turn off the
mobile phase flow.
Default: 400 bar
Pressure Stability
Specifies the stability condition required for the pump to go into a Ready state. A lower
value requires greater pressure stability before the pump state goes to Ready. A higher value
is more forgiving of pressure pulsations.

Setting Up the Gradient Program
The pump 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 pump in either the
isocratic mode or the gradient mode. In the isocratic mode, you maintain the same
proportions of solvent throughout the run.
Use the Gradient Program page to specify the solvent composition and flow rate for your
chromatographic method.
The Gradient Program page contains a gradient table with time lines for the solvent
composition and flow rate, and an interactive view that displays a graphical profile of the
solvent gradient or flow rate gradient.
Each row in the gradient table defines the solvent composition and flow rate for a specific
time point. The solvent composition columns (A%, B%, C%, and D%) work interactively
with each other, maintaining a total solvent composition of 100%.
Between time points, the solvent composition changes linearly, whereas the flow rate changes
as a discontinuous step-function.
The gradient table can contain 2 to 398 time lines.
IMPORTANT The gradient table must contain at least two time lines. For an isocratic
gradient program, the two time lines specify the same solvent composition and flow rate.
 To set up the gradient program for the Surveyor MS Pump Plus
1. Open the view for your pump.
2. Specify the general pump parameters (see “Specifying the Chromatographic Conditions

• When you select Surveyor AS Injection Logic or Manual and the Home Before
Run check box, the minimum flow rate is 10.0 μL/min.
• When you select Manual and leave the Home Before Run check box cleared, the
minimum flow rate is 0.0 μL/min.

The flow rate range is the same as for an isocratic run (see step 4b on page 80). To
produce a stable gradient, enter a flow rate of at least 25 μL/min.
b. To return the solvent conditions to those specified in the first line of the gradient
program, select First Line Conditions in the Method Finalizing list. First Line
Conditions is the default selection.
Figure 52 shows the gradient program entries for the gradient program in Table 17.
After 30 minutes the gradient program returns to the first line conditions for the
remainder of the run. To equilibrate the LC column at the first line conditions for
10 minutes, you must set the run time for the PDA detector or MS detector to
40 minutes.
Tip If you do not want the detector to acquire data during the column
equilibration period, you can add an equilibration period to the end of the
gradient program and make the gradient program time for the pump longer than
the data acquisition time for the detector.

 To specify the injection and temperature control settings for your instrument method
1. Select the injection mode:
• If you want to vary the volume of your sample injections, select the Partial Loop
option.
• If you want a high degree in injection-to-injection precision, select the Full Loop
option. When you select Full loop, the Injection Volume (μL) box becomes
unavailable.
• If you have a limited amount of sample, select the No Waste option. When you select
No Waste, the Loop Loading Speed (μL/s) box becomes available.
Note For more information about the injection modes, see “Injection Modes” on
page 19.
2. For the No Waste injection mode, type or select a loop loading speed in the Loop Loading
Speed box.
For most applications, keep the loop loading speed at its default value.
3. For the Partial Loop and No Waste injection modes, type or select an injection volume in
the Injection Volume box.
The injection volume range depends on the syringe size (see “Injection Volume Range”
on page 91).
4. In the Needle Height from Bottom (mm) box, type or select the height from the bottom
of the vial or well that the needle of the autosampler descends to before withdrawing
sample from the vial/well location.
The default value is 2 mm and the range is 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 autosampler have a depth of approximately 20 mm.
Figure 13 on page 15 shows the needle descending to a depth of 2 mm from the bottom
of a standard 1.8 mL vial.
5. In the Syringe Speed (μL/s) box, keep the syringe speed at its default value (8 μL/s for the
250 μL concentric syringe) for most applications.
If you see the sample in the needle tubing break up as the autosampler withdraws sample
from a vial or well location into the needle tubing, adjust the syringe speed.
6. In the Flush Volume (μL) box, type or select a volume from 0 to 6000 μL or keep the
value at its default of 400 μL.
7. In the Flush/Wash Source list, select a flush/wash solution.
For most applications, select Bottle (wash bottle). If you select one of the reservoir vial
locations as your flush/wash source, make sure that you load the autosampler with a
reservoir vial.

For information about the location of the 16 mL reservoir vials, see “Tray Compartment”
on page 5. For information about specifying the contents of the reservoir vials and the
wash bottle, see “Reservoir Content Page” on page 92.
8. In the Wash Volume (μL) box, keep the wash volume at its default value of 0 μL.
To wash the exterior of the needle after each injection, type a value from 1 to 6000 μL in
the Wash Volume box.
9. In the Flush Speed (μL/s) box, set a flush speed appropriate for the flush solvent:
• If you are using a flush solvent of low viscosity such as methanol, keep the flush speed
at its default (100 μL/s for the 250 μL concentric syringe)
• If you are using water or a methanol/water mixture as the flush solvent, reduce the
flush speed.
Tip If you hear a grinding noise from the autosampler as it performs a flush, lower the
flush speed.
10. In the Post-Injection Valve Switch Time (min) box, keep the time value at its default of
0 minutes for most applications. This leaves the sample loop in the inject position during
the entire run, allowing ample rinsing of the sample loop between injections.
11. In the Tray Temperature Control area, 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.
12. In the Column Oven Control area, 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.

Syringe Speed (μL/s)
Specifies the rate at which the syringe withdraws liquid from a tray vial or a plate well.
The default value and the range depend on the syringe size (see “Syringe and Loop Loading
Speeds for Injections” on page 91).
Flush Volume (μL)
Specifies the volume of liquid that the autosampler flushes through the inside of the needle,
the injection port, and the transfer tube. During a flush cycle, the injection valve is in the
inject position to prevent the flush solvent from entering the sample loop.
To reduce carryover, increase the flush volume. When the specified flush volume exceeds the
syringe capacity, the autosampler takes multiple draws from the reservoir or bottle.
Range: 0.0 to 6000.0 μL
Default: 400 μL

Specifies the flush/wash source.
Selections: bottle, RV1, RV2, RV3, or RV4
Default: bottle (wash bottle)

IMPORTANT A flush speed of 250 μL/s for the 250 μL concentric syringe is the
maximum flush speed for a solvent of low viscosity such as 100% methanol. If you are
using a solvent of higher viscosity, reduce the flush speed accordingly. For example,
because water has approximately twice the viscosity as methanol, if you are using water as
your flush solvent, lower the flush speed to 100 μL/s. At high flush speeds, viscous
solvents can cause the autosampler to make a grinding sound.
Post-Injection Valve
Switch Time (min)
At the default post-injection valve switch time of 0 minutes, the injection valve remains in
the inject position during the run.
A time value greater than 0.1 minutes specifies the time when the injection valve switches
from the inject position to the load position at the end of an injection cycle.
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 typing a
nonzero value in this box. Allow enough time for the mobile phase to backflush the sample
out of the sample loop.
Default: 0 minutes
Range: 0 to 999.0 minutes
Loop Loading Speed
(μL/s)
Specifies the rate at which the autosampler meters the sample into the sample loop for no
waste injections. During a no waste injection, the autosampler meters the sample through
the transfer tubing to the injection valve at the specified syringe speed. The injection valve
then switches to the load position, and the autosampler meters the sample into the sample
loop at the specified loop loading speed.
This parameter is only available in the No Waste injection mode.
The default value and range depend on the syringe size (see “Syringe and Loop Loading
Speeds for Injections” on page 91).
Injection Mode
Partial Loop
Select this option if you want to inject variable volumes.
IMPORTANT To make precise partial loop injections, limit the maximum injection
volume to less than half the nominal sample loop size. Because the accuracy of the
nominal volume of the sample loop is ± 20% (which means that the actual volume of the
standard 25 μL sample loop is between 20 and 30 μL), for best results, limit the maximum
injection volume to 10 μL for the standard 25 μL sample loop.

For partial loop and no waste injections, the minimum injection volume is 0.1 μL. The
maximum injection volume depends on the syringe size (see Table 20).
For optimal performance, follow these guidelines:
• For no waste injections, do not inject less than 1.0 μL and limit the maximum injection
volume to 80% of the nominal loop size minus an additional 5 μL.
• For partial loop injections, limit the maximum injection volume to 40% of the nominal

Syringe and Loop Loading Speeds for Injections
During an injection sequence, the inner plunger of the concentric syringe descends, pulling
liquid from a sample vial or well into the needle tubing. After the autosampler withdraws
sample, the XYZ arm moves the needle to the injection port. The inner plunger of the
concentric syringe ascends, pushing liquid through the transfer tubing and into the sample
loop. A stepper motor controls the speed of the plunger.
You can specify how fast, in microliters per second, the syringe withdraws liquid from a tray
vial or plate well, and then expels liquid into the autosampler injection port. The default
syringe speed and the syringe speed range depend on the syringe size (see Table 21).
The appropriate syringe speed depends on the sample. For viscous samples, use a syringe
speed lower than the default value to avoid stalling the syringe. For samples of low viscosity or
surface tension, use a lower syringe speed to prevent the sample bolus from breaking apart
during the transport process.
Tip Select the syringe size on the Communication page of the Surveyor Autosampler
Configuration dialog box. The autosampler ships with a 250 μL concentric syringe.

2. In the Run Length (min) box, type a run time from 0 to 600 minutes.
3. In the Filter Rise Time (sec) list, select a rise time from 0 to 10.0 seconds.
Rise time is inversely proportional to the amount of baseline noise. If your chromatogram
contains closely eluting peaks, minimize baseline noise while retaining maximum
resolution by selecting a rise time that is approximately one-tenth of the narrowest peak’s
width at half-height (FWHM). Increasing the rise time above this level increases peak

c. In the Wavelength Step (nm) box, type a value for the wavelength interval.
The default value is 1 nm. The maximum step size depends on the wavelength range
defined by the starting and ending wavelengths. The range is 1 to 610 nm for a scan
from 190 to 800 nm. If you are collecting spectral data for a spectral library, use a
wavelength step of 1 nm.
d. In the Sample Rate (Hz) list, select a sample rate.
For optimal integration of the chromatographic peaks, select a sample rate that
acquires a minimum of 20 points across the baseline width of the narrowest peak of
interest. For example, if the baseline width of the narrowest peak is 20 seconds, select
a sample rate of 1 Hz or higher.
Increasing the sampling rate increases the data file size.
e. In the Filter Bandwidth (nm) box, type a bandwidth.
Depending on the wavelength range defined by the starting and ending wavelengths,
the range is the subset of odd integers from 1 to 49 nm. The maximum scan range for
a particular bandwidth is limited as follows:
• Start Wavelength (minimum) = 190 nm + (bandwidth – 1)/ 2
• End Wavelength (maximum) = 800 nm – (bandwidth – 1)/ 2
Increasing the bandwidth decreases the spectral resolution (see Figure 61).

6. To collect discrete channel data, select one of the options in the Channels area, and then
make the following entries:
a. In the Sample Rate list, select a sampling rate (in data points per second). Higher data
rates for discrete channels do not add significantly to the data file size.
b. For each discrete channel (A, B, and C), type a wavelength from 190 to 800 nm in
the Wavelength (nm) box and a filter bandwidth in the Filter Bandwidth (nm) box.
Depending on the discrete wavelength, the acceptable bandwidth range is 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 bandwidth setting is 21 nm. At a bandwidth
setting of 21 nm, the reported absorbance value for 200 nm is a weighted average
from 190 to 210 nm. A value greater than 21 nm would be outside the lower range
limit of the detector, which is 190 nm.

Sample Preparation Routines
Sample preparation routines are part of the instrument method. Use the Sample Preparation
page to create a multitask routine, containing 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 dual-concentric syringe that ships with the autosampler, you must
follow an additional set of rules that maintain the proper positioning of the inner and outer
plungers of the syringe.

Sample Preparation Rules
The maximum volume that the autosampler can deposit, draw, or transfer during a sample
preparation task depends on the syringe type, the task requested, and the previous step in the
sample preparation method.
Table 28 categorizes the sample preparation tasks into three groups based on whether the task
uses the inner bore only, the outer bore only, or either bore of the dual-plunger concentric
syringe. For information about the dual-plunger concentric syringe, see “Interchangeable
Syringe” on page 14.

For the 250 μL concentric syringe, these rules restrict the arrangement of the tasks in the
sample preparation list:
• For tasks performed with the inner bore of the dual-concentric syringe, the maximum
volume (sample + air bubble) that the autosampler can draw, deposit, or transfer is
limited to the nominal size of the syringe, 250 μL.
• For tasks performed with either bore, if the sum of 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, the dual-plunger concentric syringe uses the small
bore. If this volume is greater than the nominal syringe size, the syringe uses the outer
bore.
• For tasks performed with the outer bore of the dual-plunger 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.
• Crossover between bores is not allowed. This means that you cannot add a task that uses
the outer syringe bore immediately following a task that uses the inner syringe bore.
To switch from the inner bore to the outer 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.

Building the Sample Preparation Routine
Sample preparation routines are part of the instrument method (see “Autosampler Instrument

performed in order by the autosampler before it makes an injection.
 To build a sample preparation routine
1. Do one of the following:
• To modify an existing sample preparation routine, go to step 2.
–or–
• To create a new sample preparation routine, go to step 3.
2. Import the sample preparation routine from a stored instrument method as follows:
a. Click Import.

b. Browse through your Methods folder and select the appropriate instrument method.
Then click Open.
Only the sample preparation task list contained in the stored instrument method is
imported into the current instrument method.
3. For each task that you want to add to the sample preparation routine, do the following:
a. In the Prep Operations list, select a task.
Table 29 lists the thirteen tasks that you can use to create a sample preparation
routine. When you select a task, the parameters available for the task appear below
the Add to Task List button.
Tip The syringe position and nominal volume limit the task order and transfer
volume:
• 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. These tasks home the concentric
syringe plungers.
• If the previous task used the small bore of the syringe, the transfer volume of
the current task is limited to the nominal syringe size or less. See “Sample
Preparation Rules” on page 115 for more information.
b. Make the appropriate selections and entries for each task parameter.

must follow a logical order or you will not be able to save the instrument method. For example, a draw task must
precede a deposit task. In addition, if you are using the 250 μL concentric syringe that comes with the autosampler,
you must follow an additional set of rules that allow for the proper positioning of the inner and outer plungers of the
syringe. (See “Sample Preparation Rules” on page 115).
If you are using the 2500 μL, single plunger syringe, to transfer volumes larger than 500 μL, add an optional tubing
extension assembly to the needle tubing.

4 Sample Preparation Routines
Draw, Eject, and Transfer Volumes for Sample Preparation Tasks
Draw, Eject, and Transfer Volumes for Sample Preparation Tasks
The maximum volume that the autosampler can deposit, draw, or transfer during a sample
preparation task depends on the syringe type, the task requested, and the previous step in the
sample preparation method:
• For tasks performed with the inner plunger of the concentric syringe, the maximum
volume (liquid + air bubble) that the autosampler can draw, deposit, or transfer is limited
to the nominal size of the syringe.
• For tasks performed with the outer plunger of the concentric syringe, the maximum
volume (liquid + air bubble) that the autosampler can draw, deposit, or transfer is limited
to 500 μL, except for the Wash Needle and Flush to Waste tasks, which are limited to a
range of 100 to 6000 μL, and the Mixing tasks, which are limited to a maximum of
490 μL.
Table 31 lists the maximum volumes by task.

Syringe Speed Range for Sample Preparation Tasks
The syringe speed range for sample preparation tasks depends on whether the task can use
either syringe plunger or only the inner plunger.
If you enter a speed that is invalid for the volume you are transferring, an error message
appears.
For information about the syringe speed range for the sample preparation tasks, see these

4 Sample Preparation Routines
Syringe Speed Range for Sample Preparation Tasks
Syringe Speed for Tasks that Can Use Either Plunger
The syringe speed range is determined by the type of syringe and the volume requested. For a
concentric syringe, the autosampler can use either the outer or inner plunger to draw liquid
into or expel liquid from the needle tubing.
For the tasks listed in Table 32, the autosampler uses the following:
• The outer plunger if the volume of liquid + air being transported is greater than the
nominal syringe size
• The inner plunger if the volume of liquid + air being transported is less than or equal to
the nominal syringe size

Table 33 lists the speed range for the sample preparation tasks that can use either plunger of
the concentric syringe.
Note The ToolTips for the speed parameters list a range of allowable speeds. The
minimum speed listed is valid for only the inner plunger, and the maximum speed listed is
valid for only the outer plunger of the configured syringe.
If you enter a volume that triggers the use of the outer plunger and a speed that is valid for
only the inner plunger, an error message appears when you attempt to add the task to the
sample preparation list.

Syringe Speed for Tasks that Use the Inner Plunger
The autosampler uses the inner plunger of the concentric syringe to perform the following
tasks:
• Draw From Sample
• Transfer From Sample To Sample
• Transfer From Sample To Reservoir
The syringe size determines the default syringe speed and the syringe speed range
(see Table 34).
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.
Note You select the size of the syringe by using the Syringe Type list on the
Communication page of the Surveyor AS Configuration dialog box.

b. Keep all the default parameter settings for the Transfer from Reservoir to Sample task,
except those that are shown below (see Figure 71).
Tip When accuracy is important, keep the transfer volume below the nominal
syringe size, so that the autosampler uses the inner syringe plunger. Solvent
transfers made with the inner plunger are more accurate than solvent transfers
made with the outer plunger because the stepper motor for the inner plunger
takes smaller steps and provides finer control than the stepper motor for the outer
plunger.

8. Save the instrument method (see “Saving the Instrument Method” on page 109).
To perform this sample routine, you must insert empty vials into your sample tray.
For example, to dilute five samples, place the samples in vial locations A1, A3, A5, A7,
and A9. Place empty vials in vial locations A2, A4, A6, A8, and A10. Fill reservoir vial 1
with an appropriate diluent that matches the sample matrix.
If you do not want to inject the diluted samples, create a five-line sequence that lists the
vial locations of the original samples (A1, A3, A5, A7, and A9). The original samples are
not injected.
If you want to inject the diluted samples, create a ten-line sequence that lists all the vial
locations (A1 to A10). Ensure that you use the method that contains the sample
preparation routine on the odd rows only (Rows 1, 3. 5. 7. and 9).

During the initial installation of the Surveyor Plus LC system, a Thermo Fisher Scientific field
service engineer sets up the solvent lines, primes the pulse dampener of the Surveyor MS
Pump Plus, and calibrates the PDA detector.
Note The pulse dampener of the Surveyor LC Pump Plus does not require priming.
To prepare the system for daily operation, check the status of the devices, warm up the
detector’s lamps, and remove air from the solvent lines.
To maintain optimal performance of the system, calibrate the PDA detector on a monthly
basis or whenever you move the detector, and check the light throughput to the diode array
whenever you move the detector, observe an increase in detector noise, or replace the flowcell
or lamps (see “Verifying the Performance of the PDA Detector” on page 313).
Prime the pulse dampener of the Surveyor MS Pump Plus on a monthly basis or when you

Priming the Pulse Dampener of the Surveyor MS Pump Plus
Priming the Pulse Dampener of the Surveyor MS Pump Plus
Before you can operate the Surveyor MS Pump Plus, you must prime its built-in pulse
dampener. Priming the pulse dampener involves filling the dampening coil (see Figure 87)
with a solvent, such as methanol or isopropanol. After the coil is filled with solvent, it
effectively dampens pressure pulsations from the rest of your system.
Closing the pulse dampener flush valve after you fill the coil shuts the dampening coil off
from the mobile phase stream. Because a permeable membrane separates the mobile phase
stream from the dampening coil, the solvent in the coil slowly diffuses into the mobile phase
stream. When the pump is in continuous or frequent use, prime the pulse dampener on a
monthly basis.
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.

5. Click Save.
Equilibrating the Chromatographic Column
Warming up the deuterium lamp and equilibrating the LC column reduces baseline drift. For
information about warming up the D2 lamp, see “Turning the Lamps On or Off ” on
page 163.
An LC column requires 10 to 20 column volumes to equilibrate to the initial mobile phase
conditions of an instrument method. For example, it takes approximately 17 mL of mobile
phase to equilibrate a typical 4.6 mm ID×10 cm length column.
\
To calculate the volume of an LC column, use the following equation:
Vm = Πr2 × L
Where:
Vm = volume in mL
r = column radius in cm (radius = inner diameter/2)
L = column length in cm
 To equilibrate your LC column
1. From the Thermo Xcalibur Roadmap menu, choose GoTo > Instrument Setup to
display the Instrument Setup window.
2. Download the same solvent percentages and flow rate as those contained in your method
to the pump:
• For information on downloading new solvent conditions to the Surveyor LC Pump
Plus and starting the solvent flow, see “Surveyor LC Pump Plus Direct Controls” on
page 185.
• For information on downloading new solvent conditions to the Surveyor MS Pump
Plus and starting the solvent flow, see “Surveyor MS Pump Plus Direct Controls” on
page 190.
3. In the status view for your pump (available on the Status page of Info View), monitor the
readings in the Pressure Status area to ensure that the pressure is appropriate for your
application. See “Viewing the Status of Each Device” on page 137.

Loading the Autosampler
Loading the Autosampler
Before you load your samples into the autosampler, ensure that your samples are completely
soluble in the mobile phase and that you have filtered your samples through a 0.5 μm filter (if
necessary). These techniques minimize sample precipitation in the lines and remove
particulate matter that could obstruct the flow through the autosampler’s injection valve or
the LC column. In addition, make sure that the vial caps are securely fastened onto the vials.
Before you start a sequence run, ensure that you have samples in the locations specified in
your sequence.
Note To trigger the vial sensor, make sure to position custom vials in the tray so that the
top of the vial reaches the minimum height of 1.55 inches. If you place vials that fall
below this minimum height in the tray, the vial sensor does not detect them. When the
sequence reaches a vial that is below the minimum height, the sequence halts, and the Vial
Not Found message appears.
 To load a conventional tray into the autosampler
1. Open the left door of the autosampler.
If you configured the Surveyor AS device driver to verify that the tray compartment door
is closed, the XYZ arm automatically moves to the back of the tray compartment.
Figure 37 on page 53 shows the location of the Verify Door Is Closed check box, available
in the Instrument Configuration window.
2. If necessary, use the direct controls to move the XYZ arm to the back of the tray
compartment (see “Autosampler Direct Controls” on page 192).
3. Hold the tray handle, tilting the back end of the tray down. Insert the tray runner into
the slot at the rear of the tray compartment. Lower the front of the tray into place. Then
press down firmly to seat the tray.

Working with the Cell Grid
Working with the Cell Grid
To use the Qual Browser facility, you must understand the concept of cell states and the effect
of cursor actions in a cell. 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 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
Inactive cells are not highlighted with a gray border and the pin icon in their upper-right
corners is gray. The cell in the lower portion of Figure 131 is inactive as indicated by the
absence of a gray border. Menu commands, toolbar buttons, and cursor actions do not affect
inactive cells. To zoom in on the contents of a cell or access its shortcut menu, you must make
the cell active.

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 131 is active but unpinned.
Menu commands, toolbar buttons, and cursor actions affect the active cell. If the grid does
not contain a pinned cell, clicking an inactive cell in the grid makes 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 226. The lower cell in Figure 132 is a pinned cell.
To automatically change the range of a cell by clicking in the grid, you must pin the cell. For
example, to display the spectrum for the 1 minute time point without opening the Spectrum
Ranges dialog box, pin the spectrum cell, and then click the 1 minute time point in the
inactive chromatogram cell.

Cursor Actions
Within the cells of the grid, you can use the cursor in three ways:
• A click selects a point on the cell.
• A line dragged parallel to any axis selects 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 54).

Calculating the Purity of the Chromatographic Peaks
Figure 161. Avalon Peak Detection Settings page displaying a chromatogram acquired
with the PDA detector
Calculating the Purity of the Chromatographic Peaks
The data system 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 (see “Displaying Scan Wavelength
Chromatograms” on page 233).
2. Set the integration parameters for the chromatogram (see “Determining Peak Areas” on
page 251).

4. Select the Enable check box.
5. In the Scan Threshold (μAU) 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 to 2 000 000 μAU.
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%, the data system compares all the spectral slices that fall within the
beginning and ending tick marks of the integrated peak. To limit the peak purity
calculation to a specific range of wavelengths in the scan, select the Limit Scan
Wavelength check box, and then enter a wavelength range in the Wavelength Range box.
7. Click OK to close the Peak Purity Settings dialog box, and then view the effect of your
peak purity settings.
The following figures show the effect of various settings on peak purity:
• Figure 163 shows the effect of the scan wavelength on peak purity.

LC Pump Calibration and Record Keeping
This chapter describes the calibration and record keeping procedures for the Surveyor LC
Pump Plus.
Contents
• Calibrating the Surveyor LC Pump Plus
• Recording Maintenance Information for the Surveyor LC Pump Plus
• Firmware Version Information for the Surveyor LC Pump Plus
The Surveyor LC Pump Plus is factory 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 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 and require 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.

LC Pump Calibration and Record Keeping
Calibrating the Surveyor LC Pump Plus
Calibrating the Surveyor LC Pump Plus
Two calibration options for the Surveyor LC Pump Plus affect its performance: the alpha
setting, which affects the flow rate; and the compressibility setting, which affects the pressure
pulsation of the system. The alpha setting is factory calibrated to produce an accurate flow
rate for water. The compressibility setting is set to 0.45 GPa–1, which is the compressibility
value 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. After you optimize the
compressibility setting, check the flow rate accuracy. If adjusting the compressibility setting
has affected the flow rate accuracy, adjust the alpha setting.
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 must update the pressure sensor adjustment setting. Even if you
never replace the pressure sensor, you must occasionally re-zero its output, as the readout
tends to drift under normal usage.

Calibration Options for the Surveyor LC Pump Plus
The Xcalibur data system provides the following calibration options (see Figure 168) for the
Surveyor LC Pump Plus:
• Compressibility
• Pressure Recorder Full Scale
• Flow Rate Adjustment (Alpha)
• Pressure Sensor Adjustment
• Pressure Transducer Zero
Compressibility
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.
For information on updating the compressibility setting, see “Updating and Optimizing the
Compressibility Setting” on page 266.
Effect of the Compressibility Setting
Even though liquids are relatively incompressible, the compressibility of the 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 the 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.

LC Pump Calibration and Record Keeping
Calibrating the Surveyor LC Pump Plus
The compressibility effect is caused by the portion of the cam cycle where the pistons are
compressing the mobile phase. The compressibility portion of the cam cycle extends from the
time when the primary piston starts discharging until the time 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 cannot effectively minimize the pressure pulsation.
Figure 169 shows the overlaid pressure traces for three runs of water pumped at a nominal
flow rate of 3 mL/min. The compressibility settings for the three runs were 0.45 GPa–1,
1.25 GPa–1, and 3.0 GPa–1, as labeled. The compressibility of water is 0.45 GPa–1.

Pressure Recorder Full Scale
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 Plus (see Figure 170). 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.

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 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 percent. Increasing the
alpha value by 1, however, increases the flow rate by 1 percent.
For information on setting the alpha value, see “Updating the Flow Rate Adjustment Setting”
on page 268.
Pressure Sensor Adjustment
Reset the Pressure Sensor Adjustment parameter when you replace the pressure sensor. 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 then update the pressure sensor
adjustment setting for your Surveyor LC Pump Plus.
For information on updating the pressure sensor adjustment, see “Updating the Pressure
Sensor Adjustment Setting” on page 269.
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, requiring you to
occasionally re-zero the readout. To update the pressure transducer zero value, turn off the
pump flow and open the drain valve knob. Then click the pressure transducer zero button in
the data system that operates your pump.

Scaling the Output of the Pressure Recorder Terminals
For information on using the pressure terminals on the pump’s back panel, see “Pressure
Recorder Full Scale” on page 264.
 To set the full-scale output of the pressure recorder terminals
1. Open the Calibration page for the Surveyor LC Pump (see “Accessing the Calibration
Options for the Surveyor LC Pump Plus” on page 260).
2. Enter a value from 1 to 10 in the Pressure Recorder Full Scale box (see Figure 168 on
page 261). Then click Set. For information on scaling the output of the pressure recorder
terminals, see “Pressure Recorder Full Scale” on page 264.
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 percent from the
expected value.
 To update the flow rate adjustment setting
1. Open the Calibration page for the Surveyor LC Pump (see “Accessing the Calibration
Options for the Surveyor LC Pump Plus” on page 260).
2. In the Flow Rate Adjustment (alpha) box (see Figure 168 on page 261), type a new value:
• If the actual flow rate is below the set value, increase the alpha value. If you are
pumping water, increasing the alpha value by 1increases 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 percent 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 percent above the set rate, lower the current setting
by 4. If the current setting is 5.0, enter a new setting of 1.0.

Contents
• Calibrating the Autosampler
• Autosampler Maintenance Information
• Autosampler Validation Information
The autosampler does not require calibration upon arrival at its shipping destination.
However, if you use custom vials or custom microplates, you must perform the Well Bottom
Distance calibration, which determines the actual depth of a vial or microplate well (see “Well
Bottom Distance Calibration” on page 305). If problems occur with the column oven control,
the tray temperature control, or the arm positioning, contact a Thermo Fisher Scientific
service representative. This appendix includes calibration procedures for these items; however,
to calibrate the autosampler’s temperature zones and XYZ arm position, you must have the kit
that contains the necessary test fixtures.

Calibrating the Autosampler
Calibrating the Autosampler
There are four calibration options for the autosampler:
• Column Oven Air Sensor Calibration
• Vial Tray Metal Sensor Calibration
• Arm Calibration
• Well Bottom Distance Calibration
The column oven and oven compartment temperature calibrations and the arm calibration
are typically performed by a Thermo Fisher Scientific field service representative. To perform
these calibrations yourself, you must have the service kit that contains the temperature test
fixtures. In addition, to calibrate the temperature sensors for the autosampler’s
temperature-controlled zones, your Thermo Scientific application must be capable of
providing feedback for these sensors.
Note Typically, a Thermo Fisher Scientific field service representative calibrates the
controlled temperature zones and the XYZ arm position. To perform the temperature
calibrations yourself, order the Field Service Calibration Kit (P/N 60053-62001). To
calibrate the XYZ arm, order the LED light fixture and the non-reflective target port
fixture.
If you choose to use custom vials or custom microwell plates, you must perform the
Well Bottom Distance calibration, which determines the depth of the custom vial or
microplate well. Perform this calibration you select a new custom tray configuration and each
time you use a new type of custom vial or custom microwell plate.
Note If you are controlling the autosampler from a Thermo Scientific data system other
than the Xcalibur data system, refer to the Help provided with your data system for
information about accessing the Calibration dialog box for the autosampler.
 To open the Calibration dialog box for the autosampler

Arm Calibration
During an injection, the XYZ arm moves between the specified vial or well location and the
injection port. When you move the autosampler, you can jar the XYZ arm, causing it to lose
alignment.
Performing the arm calibration procedure requires you to visually align the XYZ arm over the
injection port. To make this visual alignment, you must replace the needle with an LED light
fixture that shines a small beam of red light onto the port and replace the stainless steel
injection port with a non-reflective target fixture. These test fixtures do not come with the
autosampler; you must order them from Thermo Fisher Scientific.
After following the instructions in the Arm Calibration wizard to adjust the XYZ arm
alignment, test the alignment by making a set of injections from one or two 384-well
microplates. The microplate carrier and the 384-well microwell plates are provided in the
Autosampler Accessory Kit.
To calibrate the XY position of the XYZ arm, you must have these items:
• LED light fixture (P/N 60357-60021)
• Target port fixture (P/N 60357-20021)
• Microplate carrier
• One or two 384-well microtitre plates
• Masking tape

Well Bottom Distance Calibration
The autosampler supports custom vials and well plates in addition to the standard 1.8 mL
vials, 96-well plates, and 384-well plates. However, to use custom vials or well plates, you
must first determine how far the autosampler needle must travel to reach the bottom of the
vials or wells.
Use the Well Bottom Distance wizard to determine 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.
IMPORTANT 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 microwell plate.
To perform a well bottom distance calibration, follow these procedures in order:
1. Starting the Well Bottom Distance Wizard

10 Autosampler Calibration and Record Keeping
Calibrating the Autosampler
Using the Needle Sensor to Determine the Well Bottom Distance
The autosampler has a needle sensor that can determine the bottom distance of custom vials
or microplate wells.
 To determine the well bottom distance with the autosampler’s needle sensor
1. Remove the cap or lid from your vial or well plate.
IMPORTANT Remove vial caps or well plate lids before performing an active well
bottom distance calibration. As the needle pierces a vial cap or a well 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 autosampler tray compartment,
check the height limitations for 96-well and 384-well plates listed in the hardware
manual for your autosampler. Tall objects will stall the autosampler arm.
2. Place the vial into a tray or the well plate into a carrier, and then place the tray or carrier
into the tray compartment of the autosampler.
3. In the Calibrate at Well/Vial position box (see Figure 214), type a vial or well location.
Note If you are calibrating the bottom distance of a vial, verify that you have placed a
vial in the selected location.
Figure 214. Calibrate to find page
4. Click Set Calibration to activate the autosampler.
After the XYZ 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 XYZ arm moves to
the home position. In the Well Bottom Distance wizard, the new bottom distance
calibration value appears at the top of the page.
5. Click Finish to accept the calibration.

PDA Detector Performance Check and Calibration
This chapter describes the performance verification and calibration procedures for the PDA
detector.
Contents
• Verifying the Performance of the PDA Detector
• Calibrating the PDA Detector
The PDA detector is factory tested for linearity, noise, and drift. Because of the sensitivity of
its optical bench, adjust the light throughput to the diode array and recalibrate the PDA
detector after you install it, and each time you move it, change its flow cell, or replace either of
the lamps.
Verifying the Performance of the PDA Detector
Before you perform either calibration procedure, turn on both lamps (see “Turning the Lamps
On or Off ” on page 163), let the temperature of the detector stabilize for approximately
one hour, and adjust the light throughput to the diode array detector.
To adjust the light throughput to the diode array, follow these procedures:
• Creating a Display Method
• Adjusting the Light Throughput to the Diode Array
Creating a Display Method
Methods that display a plot of integrated light intensity versus diode number have a .spda file
extension.
 To create a display method for the PDA detector
1. In the view bar of the Instrument Setup window, click the Surveyor PDA Plus button.
The view for the PDA detector appears.
2. In the Units area, select the Diode/Intensity option (see Figure 217).

the Spectra area:
• Start Diode (diode num) = 2
• End Diode (diode num) = 511
• Diode Step (diode num) = 1
Note For a display method, the following parameters are not downloaded to the PDA
detector: run length, filter rise time, and sample rate.
4. Choose File > Save to save the display method.
An error message appears (see Figure 218).

5. Click OK.
6. From the menu bar, choose Surveyor PDA > Direct Control.
7. Click Yes.
The Save PDA Display Method dialog box appears.
8. Save the display method.
The data system saves the method with a .spda file extension.
Note The .spda file extension is a special file extension used for all method files based
on Diode/Intensity units. When you create a file with an .spda file extension, you can
only load and use it in the Direct Control dialog box.
After you save the method, the Direct Control dialog box appears with the Display page
open.
9. To adjust light throughput to the diode array, go to “Adjusting the Light Throughput to
the Diode Array.”
Adjusting the Light Throughput to the Diode Array
The PDA Detector has two attenuators that control the light throughput from the lamps.
Manually adjusting the position of the attenuators increases or decreases the amount of light
falling onto the array.
Adjust the light throughput to the diode array whenever you do the following:
• Observe an increase in the detector noise level.
• Move the detector.
• Replace either lamp or the flowcell.
The first time that you adjust the attenuators, you must create a display method that records
light intensities. You can identify display methods by their .spda file extension. After creating
the method for adjusting the attenuators, save it with a descriptive name, such as
diagnostics.spda, and store it for future use to 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, follow these procedures in order:
1. “Preparing the LC System for an Attenuator Adjustment” on page 316
2. “Adjusting the Attenuators” on page 317
3. “Adjusting the Attenuators” on page 317

Preparing the LC System for an Attenuator Adjustment
 To prepare the LC system for an attenuator adjustment
1. Ensure that the lamps are on.
You can view the lamp status from the Configuration page of the Direct Control dialog
box or from the PDA detector view of the Status page of the Information view. For
information about the Configuration page, see “Configuration Page” on page 171.
2. Replace the LC column with a flow restrictor.
3. Start pumping HPLC-grade water at a flow rate of 1 mL/min through the flowcell.
Go to the next procedure, “Accessing the Attenuators.”
Accessing the Attenuators
 To access the attenuators
1. Open the front doors of the detector.
2. Unscrew the captive screw, and then remove the flowcell cover.
The attenuators are located on the right side of the front panel. Two black tabs are
attached to the attenuators for manual adjustments (see Figure 219).
The left tab controls the light throughput from the deuterium lamp (UV region) and the
right tab controls the light throughput from the tungsten lamp (Visible region). Moving
an attenuator tab up increases the light throughput, and moving the tab down decreases
the light throughput to the diode array.

For information about calibrating the PDA detector, see these topics:
• Calibration Page for the PDA Detector
• Performing a Dark Current Calibration
• Performing a Wavelength Calibration
• Creating and Editing a Custom Wavelength Calibration List
To calibrate the wavelength accuracy of the optical bench, the PDA detector uses a holmium
oxide reference solution, one of the four calibration files provided with the Xcalibur data
system, or your own custom wavelength calibration file.
IMPORTANT Before you perform a wavelength calibration, verify that the diode array is
not saturated (see “Adjusting the Light Throughput to the Diode Array” on page 315).

PDA Detector Performance Check and Calibration
Calibrating 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.
The environmental conditions of your laboratory can cause the dark current of the diode
array to increase over time. For best results, perform an array calibration (dark current) after
any of the following events occur:
• After 100 hours of use or monthly, whichever comes first
• Whenever a 5 °C change in the operating environment 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, warm up the lamps for one hour before you perform a dark current calibration.
Warming up the lamps for one hour allows the detector to equilibrate to its normal operating
temperature.
The lamps turn off during the dark current calibration routine. After the dark current
calibration routine finishes, the lamps turn 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 one hour for the lamps to equilibrate.
3. Open the Calibration page for the PDA detector.

Performing a Wavelength Calibration
The alignment of the spectrum on the diode array depends on the physical alignment of
various components of the optical bench. The alignment can become offset if the detector is
sharply jolted, in shipping, for example. Such bumps and jars can slightly change the
wavelength of light reaching the photodiode array. The automated wavelength calibration
procedure determines the detector’s wavelength accuracy and adjusts the detector’s wavelength
algorithm to correct for any misalignment.
 To perform a wavelength calibration

Making a Single Injection from the Tune Window
If you are using the Surveyor Plus LC system as an inlet to a Thermo Scientific mass
spectrometer, you can use the direct control dialog boxes available from the Tune window to
make a single injection and acquire data.
For information about setting up the LC/MS system, refer to the Getting Connected Guide
for your mass spectrometer. For information about acquiring raw data files from the tune
program for your mass spectrometer, refer to the Getting Started Guide for your mass
spectrometer.
Note You can use the PDA Direct Control dialog box to perform diagnostic tests such as
checking the performance of the deuterium lamp. To acquire PDA data for a single
injection, you must run a single row sequence from the Sequence window.
 To inject a single sample from the Tune window
1. Prepare the LC system for operation. See Chapter 5, “Daily Operation.”
2. From the Tune window for your Thermo Scientific mass spectrometer, choose Setup >
Inlet Direct Control.
The Inlet Direct Control dialog box that contains tabbed pages for each configured LC
device appears.
3. Start the solvent flow from the pump as follows:
• For the Surveyor LC Pump Plus, click the Surveyor LC Pump tab. In the Method
area (see Figure 246), enter the appropriate values for the flow rate and the solvent
percentages. Click Download. In the Pump area, click Pump On to start the solvent
flow.

Figure 248. Surveyor AS page of the Direct Inlet Control dialog box
c. In the Vial box, type the location of the sample. Ensure that you have placed a sample
in this location.
For information about the vial and well notation, see “Vial and Well Notation” on
page 6.
d. In the Volume (μL) box, type the volume that you want to inject.
e. Select the injection mode: Full, Partial, or No Waste. For more information, see
“Injection Modes” on page 19.
f.
Click Apply.
The autosampler loads the sample into the sample loop connected to the injection
valve as follows:
The XYZ arm of the autosampler moves to the sample location, and then lowers
the needle into the sample vial. The syringe plunger descends, drawing sample
into the needle tubing. The XYZ arm moves back to the injection port, and then
lowers the needle into the injection port. The syringe plunger ascends, pushing
sample into the injection port, through the transfer tubing, and into the sample loop
of the injection valve.
5. On the Surveyor MS Pump Plus page, select the Release Injection check box.
The injection valve switches to the inject position, allowing mobile phase to backflush the
sample out of the sample loop and into the LC column.
