Contents • Quantitative Analysis with LCquan • LCquan for Web Access • LCquan for Citrix Quantitative Analysis with LCquan The LCquan application is a complete quantitative analysis software package that lets you acquire data specifically for an analyte of interest, to quantitate the results, and to produce reports. For more information about quantitative analysis concepts, see Appendix A, “Quantitative Analysis Overview.” This section contains the following topics: • Overview of LCquan • LCquan Folder Structure • LCquan Applications Menu • Acquiring and Processing Data with LCquan • LCquan for Citrix Thermo Scientific LCquan User Guide 1 1 Introduction Quantitative Analysis with LCquan Overview of LCquan The LCquan application is divided into four main windows: Instrument Setup, Acquisition, Explore, and Quantitate. By using these windows, you can develop instrument methods, acquire data, explore data, and process data files. Instrument Setup Window Use the LCquan Instrument Setup window to develop instrument methods for the instruments you selected in the Xcalibur Instrument Configuration window. An instrument method is a set of experimental parameters and operating settings for a specific instrument, such as an autosampler, LC pump or MS pump, mass spectrometer, divert valve, or syringe pump. Within the Instrument Setup window, you can create new methods or modify existing methods. You can also import previously collected data files to help you set up time segments and scan events based on the acquired data. The Instrument Setup window within LCquan functions similar to the Instrument Setup window of the Xcalibur Home Page. The Instrument Setup window contains separate pages for each instrument that you selected in the Xcalibur Instrument Configuration window (see Figure 1). Note The Instrument Setup window is not available in the LCquan for Web Access or Citrix application. 2 LCquan User Guide Thermo Scientific 1 Introduction Quantitative Analysis with LCquan Figure 1. Instrument Setup window Thermo Scientific LCquan User Guide 3 1 Introduction Quantitative Analysis with LCquan Acquisition Window In the LCquan Acquisition window, you can set up a sequence of samples for acquisition (see Figure 2). The sequence can contain unknown samples, calibration standard samples, quality control samples, and blank samples. After you have defined a sequence, you can specify acquisition options and processing action options for the sequence and start running it. The Acquisition window also contains a real-time display so you can watch updates of the acquisition status and the data being acquired. The Acquisition window contains the Setup Sequence view, the Run Sequence dialog box, and the Status view. Note The Acquisition window is not available in the LCquan for Web Access or Citrix application. Figure 2. 4 Acquisition window LCquan User Guide Thermo Scientific 1 Introduction Quantitative Analysis with LCquan Explore Window In the Explore window, you can display a multi-peak chromatogram for a single sample and experiment with peak detection and integration parameters to see how they affect the chromatogram (see Figure 3). Use the Explore window to determine the optimum parameters used in the processing method. The LCquan application can also generate a peak list that you use to generate the quan components in the processing method. The Create Explore Methods view of the Explore window opens. Figure 3. Explore window Thermo Scientific LCquan User Guide 5 1 Introduction Quantitative Analysis with LCquan Quantitate Window In the Quantitate window, the LCquan application steps you through a procedure for batch processing raw files during quantitative analysis (see Figure 4). Because the LCquan window incorporates an integrated calibration curve, peak integration, and results view, you can interactively review and rework standards, QCs, and unknowns in one window. You can also enter the Quantitate window to process the acquired data as you acquire it. Figure 4. Quantitate window The LCquan application uses a processing method to automatically determine the concentration (or amount) of the sample being analyzed. The processing method measures the response of the detection system to the compounds in your sample by integrating the area under each peak. 6 LCquan User Guide Thermo Scientific 1 Introduction Quantitative Analysis with LCquan After measuring several known standards, the LCquan application constructs a calibration curve that it uses to accomplish the quantitative analysis of unknown samples. It provides a number of options for fitting the calibration data to generate the calibration curve. You can have it fit the calibration data to the following curve types: • Linear • Quadratic • Linear log-log • Quadratic log-log • Average response factor (RF) • Point-to-point • Cubic spline • Locally weighted You can also have the LCquan application weight the calibration data with the following weighting functions when performing the least squares fit to the calibration data: • Equal • 1/X • 1/X2 • 1/Y • 1/Y2 • 1/S2, where S2 = X2 + Y2 In addition, you can have it ignore the origin, use the origin as a data point, or force the calibration curve to include the origin. The Quantitate window contains these views: Create Method, Create Sequence, Survey, Review All Results, and Review Reports. Thermo Scientific LCquan User Guide 7 1 Introduction Quantitative Analysis with LCquan LCquan Folder Structure When you start a new quantitative analysis project, the LCquan application creates a hierarchical folder structure for the project on the hard drive. The top-most level in the file structure is the study folder. This folder is used to organize one or more workbook folders. Each workbook folder holds all the information used by the LCquan application for an individual quantitative analysis project. The workbook folder contains the LCquan file (.lqn), the instrument method files (.meth), and the audit log files. In addition, the workbook folder contains these folder names: Exports, Imports, raw files, and Temp. The Exports folder stores copies of all files that are exported from the LCquan application, such as report files. The Imports folder stores a copy of legacy files that you import into the workbook, such as instrument method files or sequence files. The raw files folder contains acquired data files (.raw), and any imported raw files. The Temp folder contains backup and temporary files that it uses. When you create a new project, the LCquan application requires you to name the study folder and the workbook folder. You can have as many different workbooks in the same study folder as you want, but each workbook must have a unique name. This is convenient for organizing your quantitative analysis projects. For example, you can use one study folder to organize all the separate quantitative analysis projects that you are doing for a particular client. You cannot rename the folders that the LCquan application creates in the workbook folder. The LCquan application manages all the files associated with the project. You do not have to remember what individual files are named or where they reside on your hard drive. All necessary files are contained within the workbook. In addition, it uses a file tracking feature to maintain a secure file system. Check with your administrator if you have problems with the security configuration. IMPORTANT Always use the LCquan application to open and modify the workbook and its associated files. To maintain secure file operations, it tracks the files in the workbook to ensure that none has been modified by an external process. If you modify a file in the workbook by using another software application (including Xcalibur), it prevents you from reopening the workbook. 8 LCquan User Guide Thermo Scientific 1 Introduction Quantitative Analysis with LCquan LCquan Applications Menu To provide quick access to external applications, you can add them to the Apps menu.

Acquiring and Processing Data with LCquan With the LCquan application, quantitative analysis usually involves the following processes. The order of some of these processes is not rigid. For example, before you acquire data, you can create the processing method and processing sequence and use these to define the acquisition sequence. 1. Developing an instrument method (not available for the Web Access or Citrix environments): The LCquan application uses an instrument method to store the specific set of parameters that operate the autosampler, LC pump or MS pump, mass spectrometer, divert valve, or syringe pump during analysis. For more information, see Chapter 2, “Preparing to Perform Quantitative Analysis.” 2. Building an acquisition sequence of samples (not available for the Web Access or Citrix environments): 10 LCquan User Guide Thermo Scientific 1 Introduction Quantitative Analysis with LCquan An acquisition sequence defines each sample as a standard, unknown, QC, or blank, and identifies its position on an autosampler tray (if appropriate). For more information, see Chapter 2, “Preparing to Perform Quantitative Analysis.” 3. Acquiring data (not available for the Web Access or Citrix environments): With LCquan you can run one sample or a series of samples from the current acquisition sequence. For more information, see Chapter 2, “Preparing to Perform Quantitative Analysis.” 4. Exploring your data: The Explore window is a “sandbox” where you can open a raw file and play with peak detection and integration parameters that you use in the Quantitate window. For more information, see Chapter 3, “Exploring the Data.” 5. Creating a processing method: The LCquan application uses a processing method to identify, detect, and integrate components in a chromatogram, generate calibration curves, quantify unknowns, and produce reports. For more information, see Chapter 4, “Creating a Processing Method.” 6. Building a processing sequence: A processing sequence consists of a list of sample data files and includes information about sample type and calibration or QC level. For more information, see Chapter 5, “Creating a Processing Sequence.” 7. Processing the raw files and reviewing the calibration and quantitative analysis results: After the LCquan application processes the raw file, you can evaluate and rework the calibration standards by modifying the peak detection and integration settings. You can also manually integrate peaks. For more information, see Chapter 6, “Processing the Raw Files and Reviewing the Analytical Results.” 8. Creating reports: The LCquan application provides both standard and custom-printed reports. Standard reports contain preselected methods and results summaries. Custom reports contain methods and results summaries that you select from a list of options. For more information, see Chapter 6, “Processing the Raw Files and Reviewing the Analytical Results.” Thermo Scientific LCquan User Guide 11 1 Introduction LCquan for Web Access LCquan for Web Access The LCquan application supports the Thermo Scientific Web Access Server, which is hosted on a Web page.

These parameters include the operating settings for the instrument (collectively referred to as the instrument method) and any optional instrument settings to be used before or after the LCquan application runs a sequence of samples (startup method and shutdown method, respectively). The parameters that are displayed in the Instrument Setup window depend on the instrument that you select in the pane on the left side of the window. Note The Instrument Setup window is not available in the LCquan application for Web Access or Citrix. Instrument setups are specific to each instrument. Refer to your hardware manual for setup instructions for your instrument. This section contains the following topics: • Creating Instrument Methods • Importing an Existing Instrument Method 26 LCquan User Guide Thermo Scientific 2 Preparing to Perform Quantitative Analysis Introduction to the Instrument Setup Window Creating Instrument Methods You must configure the instrument before you can define an instrument method. To configure an instrument, close the LCquan application and Xcalibur data system and choose Start > Programs > Thermo Foundation 1.0 > Instrument Configuration. To create instrument methods for your configured instruments 1. Select an instrument by clicking its icon in the navigation pane. The LCquan application displays one or more pages of instrument parameters. 2. Select Instrument Method. 3. Set the instrument settings that are appropriate for your experiment. The Instrument Setup window might contain multiple views or dialog boxes. 4. For each instrument that you want to set up, repeat steps 1 through 3. 5. When you want to create an optional startup method that the LCquan application will run before it runs the first sample in an acquisition, do the following: a. Select the appropriate instrument by clicking its icon in the navigation pane. b. Click Startup Method. c. Specify the startup settings for the instrument. 6. When you want to create an optional shutdown method that the LCquan application will run after it runs the last sample in an acquisition, do the following: a. Select the appropriate instrument by clicking its icon in the navigation pane. b. Click Shutdown Method. c. Specify the shutdown settings for the instrument. When you create or modify an instrument method, the LCquan application automatically saves it when you leave the Instrument Setup window. The file name is based on the workbook name (for example, 3-Drugs Workbook.meth). After you save a method in the workbook, it remains part of the workbook even if the configured instrument is removed. Thermo Scientific LCquan User Guide 27 2 Preparing to Perform Quantitative Analysis Introduction to the Acquisition Window Importing an Existing Instrument Method Instead of creating a new method, you can import an existing instrument method into your current workbook. You can use the method as is or you can edit it. Import an instrument method in one of the following ways: Use the New Study or Workbook Wizard When you create a new workbook, the New Study or Workbook Wizard gives you the option of importing instrument methods, acquisition sequences, and processing parameters to initialize the new workbook. Import this data from an existing workbook, or import an instrument method from an individual legacy file (.meth). See “Creating a New Study and Workbook” on page 13. Use the Import Instrument Method File dialog box Choose File > Import Instrument Method to open the Import Instrument Method File dialog box. Use this dialog box to import an instrument method from an individual legacy file (.meth). Introduction to the Acquisition Window Use the Acquisition window to define an acquisition sequence, run individual samples and sequences, and monitor real-time data acquisition. This section describes the features of the following views: • Using the Setup Sequence View • Using the Run Sequence Dialog Box • Using the Status View Use the navigation pane on the left side of the window to select the view or function. 28 LCquan User Guide Thermo Scientific 2 Preparing to Perform Quantitative Analysis Using the Setup Sequence View Using the Setup Sequence View Use the Sequence Setup view to modify an acquisition sequence containing Unknown samples, calibration Standard samples, quality control (QC) samples, and Blank samples. The Setup Sequence view includes the following: • Acquisition Sequence Header • Acquisition Sequence History • Acquisition Sequence Grid A sequence is a defined set of experiment parameters that define operating settings for a single sample or list of samples. The acquisition sequence is a list of samples and defined settings that the LCquan application uses to acquire data. The acquisition sequence can contain Unknown samples, calibration Standard samples, quality control (QC) samples, and Blank samples. Each sample can be defined by some or all of the following settings: • Sample type • File name • Sample identification • QC or Standard level • Internal standard correction amount Thermo Scientific LCquan User Guide 29 2 Preparing to Perform Quantitative Analysis Using the Setup Sequence View • Dilution factor • Vial position • Injection volume • Sample volume • Sample weight • Sample name • Additional user-defined parameters (such as Study, Client, Laboratory) Each row of the sequence corresponds to one sample injection.

Thermo Scientific LCquan User Guide 63 2 Preparing to Perform Quantitative Analysis Using the Setup Sequence View Acquisition Sequence Grid Column Parameter Definitions The following table defines the available columns for the acquisition sequence grid. Table 19. Acquisition sequence grid column parameters (Sheet 1 of 3) Parameter Description Sample Type Displays the type of sample described by the sequence row. The sample type defines how the LCquan application processes the sample data. Each sample must be classified as one of the following LCquan sample types: • • • • FileName Unknown Blank QC (quality control) Standard Displays the name of the raw file that contains the sample data. The file name is a combination of the base file name prefix assigned to the sequence and a sequential sequence number. When the default sequence starting number 1 was not changed, the suffix number is the same as the row number of the sequence: 001, 002, and so on. When the default sequence starting number was changed to another number, the first sample has the starting number and subsequent rows in the sequence are incremented by 001. For example, if the starting number was 100, the file name for the first sample would have a suffix of 100, the second sample would have a suffix of 101, and so on. 64 LCquan User Guide Sample ID Displays the sample ID for each data file. The sample ID is an alphanumeric string of characters that identifies a sample. Level Indicates the level defined for a calibration sample or quality control sample. Thermo Scientific 2 Preparing to Perform Quantitative Analysis Using the Setup Sequence View Table 19. Acquisition sequence grid column parameters (Sheet 2 of 3) Parameter Description ISTD Corr Amt Specifies an updated amount of internal standard for the corresponding sample. The default value is 0.0. For each component defined as an internal standard, a bulk adjustment factor can be applied to the base response of each internal standard defined in the processing method. When no adjustment is required, verify that a value of 0.000 is entered in the ISTD Corr Amt box. When an adjustment is required, enter the actual value of all internal standard amounts or concentrations in the sample into the ISTD Corr Amt box for the sample row or rows requiring adjustment. The new value entered must use the same units as specified in the processing method. Do not enter the units of measurement into the box. For example, for 20 ng, type 20. Dil Factor Displays the dilution factor used to prepare the sample. The valid range is 0.000 to 10 000.000. The LCquan application interprets a value of 0.000 as no dilution. When you have specified a processing method for the current sequence, the LCquan application automatically enters the Dil Factor value from the processing method settings. Vial Pos Displays the sample’s position number in the autosampler. Inj Vol Displays the injection volume in microliters of sample to be injected. When you are using an autosampler, you can set the default injection volume in the Autosampler dialog box in the Instrument Setup window. The minimum and maximum injection volumes that you can use depend upon the Autosampler you select. The usable range is dependent upon the injection mode and might be smaller than the range displayed in the status bar. For more details, consult your Autosampler manual. Sample Vol Displays the volume of a component that has been placed in the sample. The unit for this volume is specified in the Xcalibur Processing Setup window and is included only in LCquan reports.

Thermo Scientific LCquan User Guide 73 2 Preparing to Perform Quantitative Analysis Using the Run Sequence Dialog Box Table 20. Run Sequence parameters (Sheet 4 of 4) Parameter Description After Sequence Set System On Keeps the system in the On state when the current sequence is completed. When On is selected, you can run another sequence without waiting. All power and flows are maintained at operational levels. Default: On Note This option has the same effect as choosing Actions > Devices On. Standby Keeps the system in the Standby state when the current sequence is completed. When you select Standby, you can run another sequence with only a short delay between runs. Some devices do not have a Standby feature. For devices with this feature, a power-saving or consumable-saving mode is entered, and the devices can be switched back on in approximately 15 minutes or less. Depending the instrument, this state turns gas and liquid flows to Off, but maintains heaters and other subsystems in an On state so that there is no warm-up time required when you change from Standby to On. Note This option has the same effect as choosing Actions > Devices Standby. Off Keeps the system in the Off state when the current sequence is completed. The Off state indicates that all power to the instrument, which can be controlled by the LCquan software, is turned Off. This includes power to all heaters and most subassemblies, but in some cases not all subassemblies. Some devices do not have an Off feature. For devices that do have this feature, a power-saving or consumable-saving mode is entered and you can switch the devices back on in an undetermined time. When several sequences are queued, the power setting of the last submitted sequence is used. Note This option has the same effect as choosing Actions > Devices Off. Caution The Off state does not guarantee that all voltages are turned off nor does it indicate that all heated components are at room temperature.

To specify a peak signal-to-noise cutoff, enter a Peak S/N Cutoff value. b. To use a valley detection approximation method to detect unresolved peaks, enter Rise Percentage value and a Valley S/N value. c. Choose whether the noise used in calculating S/N values is calculated using an RMS calculation or Peak-to-Peak resolution threshold. 114 LCquan User Guide Thermo Scientific 3 Exploring the Data Creating Explore Methods Table 35. Genesis Peak Integration parameters (Sheet 1 of 2) Parameter Description Advanced Opens the Genesis Advanced Component Options dialog box. S/N Threshold This multiplier specifies a signal-to-noise threshold for peak integration. Only peaks with a signal-to-noise ratio greater than this value are integrated. Range: 0.0 to 999.0 Default multiplier: 0.5 Valley Detection Enabled Detects unresolved peaks with the valley detection approximation method. The LCquan application drops a vertical line from the apex of the valley between unresolved peaks to the baseline. The intersection of the vertical line and the baseline defines the end of the first peak and the beginning of the second peak. Expected Width (sec) This multiplier specifies an expected peak width parameter that controls the minimum width that a peak is expected to have when valley detection is enabled. With valley detection enabled, any valley points nearer than half the expected width to the top of the peak are ignored. If a valley point is found outside the expected peak width, the LCquan application ends the peak at that point. It always ends a peak when the signal reaches the baseline, independent of the value set for the expected peak width.Range: 0.0 to 999.0 Default multiplier: 0.0 Units: seconds Note Valid only when you select the Valley Detection Enabled check box. Constrain Peak Width Constrains the peak width of a component during the peak integration of a chromatogram. You can set values that control when peak integration is turned on and off by specifying a peak height threshold and a tailing factor. Selecting this activates the Peak Ht (%) and the Tailing Factor parameters. Thermo Scientific LCquan User Guide 115 3 Exploring the Data Creating Explore Methods Table 35. Genesis Peak Integration parameters (Sheet 2 of 2) Parameter Description Peak Ht (%) Specifies a percentage of the total peak height. This is the minimum that a signal must be above the baseline before integration is turned on or off. This option is available only when you select the Constrain Peak Width option. Range: 0 to 100% Default multiplier: 5.0% The peak height percentage is defined as follows: Tailing Factor Specifies a value for the factor that controls how the LCquan application integrates the tail of a peak. This factor is the maximum ratio of the trailing edge to the leading side of a constrained peak and calculates the retention time of the maximum extent of the right edge of the tailing peak. This option is available only when you select the Constrain Peak Width option. Range: 0.5 to 9.0 Default multiplier: 1.0 (1.0 has no effect) Table 36 describes Genesis advanced component options. 116 LCquan User Guide Thermo Scientific 3 Exploring the Data Creating Explore Methods Figure 18. Genesis Advanced Component Options box Table 36. Genesis Advanced Component Options parameters (Sheet 1 of 2) Parameter Description Peak Edge Detection Chromatogram peak detection criteria using the peak signal-to-noise (S/N) cutoff value. Peak S/N Cutoff The peak edge is set to values below this defined S/N. This test assumes an edge of a peak is found when the baseline adjusted height of the edge is less than the ratio of the baseline adjusted apex height and the peak S/N cutoff ratio. When the S/N at the apex is 500 and the peak S/N cutoff value is 200, the LCquan application defines the right and left edges of the peak when the S/N reaches a value less than 200. Range: 50.0 to 10000.0 Thermo Scientific LCquan User Guide 117 3 Exploring the Data Creating Explore Methods Table 36. Genesis Advanced Component Options parameters (Sheet 2 of 2) Parameter Description Valley Detection Valley detection approximation method to detect unresolved peaks. Rise Percentage The percentage that the peak trace can rise above the baseline after passing through a minimum (before or after the peak). This method drops a vertical line from the apex of the valley between unresolved peaks to the baseline. The intersection of the vertical line and the baseline defines the end of the first peak and the beginning of the second peak. When the trace exceeds rise percentage, the LCquan application applies valley detection peak integration criteria. This test is applied to both the left and right edges of the peak. The rise percentage criteria is useful for integrating peaks with long tails. Range: 0.1 to 500.0 Valley S/N Specifies a value to evaluate the valley bottom. Using this parameter ensures that the surrounding measurements are higher. Range: 1.0 to 100.0 Default: 2.0 Report Noise As RMS or Peak to Peak Determines if the noise used in calculating S/N values is calculated using an RMS calculation or peak-to-peak resolution threshold. ICIS Peak Integration Use the ICIS Peak Integration area to define ICIS peak detection algorithms to be applied to the active raw file (see Figure 19). To specify ICIS peak integration parameters 1.

You can modify the Avalon estimates by entering your own values and clicking Add to save your Start or End Threshold. The Start Threshold depends on the RMS noise in the chromatogram. It is the fundamental control used for peak detection, so picking the best Start Threshold is essential for high-quality data collection. Units: Absolute value of peak area (counts x seconds) Bunch Factor The number of points grouped together during peak detection. This method groups several chromatographic points during integration without affecting the final area calculation of the peak. Range: 1 to 6 Note A high bunch factor groups peaks into clusters. Area Threshold Controls the area cutoff. Any peak with a final area less than the area threshold is not recorded. Format: units of area for the data P-P Resolution Defines how much peak overlap must be present before two or more adjacent peaks create a peak cluster. Peak clusters have a baseline drop instead of valley-to-valley baselines. This is specified as a percent of peak height overlap. Negative Peaks Automatically resets after a negative peak has been found. Tension Controls how closely the baseline follows the overall shape of the chromatogram. A lower tension traces the baseline to follow changes in the chromatogram more closely. A high baseline tension follows the baseline less closely, over longer time intervals. Units: minutes Tangent Skim Enables tangent skim on any peak clusters. By default, the LCquan application chooses the tallest peak in a cluster as the parent (solvent) and detects peaks on either side (or both sides) of the tallest peak. You can also identify which peak in the cluster is the parent. Tangent skim automatically resets at the end of the peak cluster. 126 LCquan User Guide Thermo Scientific 3 Exploring the Data Creating Explore Methods Table 40.

Thermo Scientific 4 Creating a Processing Method Specifying Method Identification Summing Ions Dialog Box Use the Summing Ions dialog box to specify for ion summing the mass-to-charge ratios and scan filters of up to five ions. Ion summing creates a single chromatogram by summing together up to five chromatograms. Ion summing can increase sensitivity because it sums the chromatograms of related masses, for example, water loss, adducts, isotopes, or multiply charged peptides. Ion summing provides the best results when chromatographic peaks have similar retention times and peak shapes, and are identified by a unique scan filter, mass filter, or both. Ion summing is data processing only and does not affect the original raw data. The LCquan application can easily reconstruct and report the original chromatograms that are part of the summed chromatogram. You cannot use ion summing and ion ratio chromatograms together with the same component. Thermo Scientific LCquan User Guide 187 4 Creating a Processing Method Specifying Method Identification Table 69. Summing Ions parameters Parameter Description Mass (m/z) Specifies one or more mass-to-charge ratios or ranges of mass-to-charge ratios of an ion whose chromatogram the LCquan application uses for ion summing.

For a detailed description of advanced parameters, see “Genesis Advanced Component Options parameters” on page 199. Figure 27. Genesis Peak Integration area Table 70. Genesis Peak Integration parameters (Sheet 1 of 3) Parameter Description Advanced Opens the Genesis Advanced Component Options dialog box. S/N Threshold This multiplier specifies a signal-to-noise threshold for peak integration. Only peaks with a signal-to-noise ratio greater than this value are integrated. Range: 0.0 to 999.0 Default multiplier: 0.5 Valley Detection Enabled Detects unresolved peaks with the valley detection approximation method. The LCquan application drops a vertical line from the apex of the valley between unresolved peaks to the baseline. The intersection of the vertical line and the baseline defines the end of the first peak and the beginning of the second peak. 196 LCquan User Guide Thermo Scientific 4 Creating a Processing Method Specifying Method Identification Table 70. Genesis Peak Integration parameters (Sheet 2 of 3) Parameter Description Expected Width (sec) This multiplier specifies an expected peak width parameter that controls the minimum width that a peak is expected to have when valley detection is enabled. With valley detection enabled, any valley points nearer than half the expected width to the top of the peak are ignored. If a valley point is found outside the expected peak width, the LCquan application ends the peak at that point. It always ends a peak when the signal reaches the baseline, independent of the value set for the expected peak width. Range: 0.0 to 999.0 Default multiplier: 0.0 Units: seconds Note Valid only when you select Valley Detection Enabled. Constrain Peak Width Constrains the peak width of a component during the peak integration of a chromatogram. You can set values that control when peak integration is turned on and off by specifying a peak height threshold and a tailing factor. Selecting this activates the Peak Ht (%) and the Tailing Factor parameters. Thermo Scientific LCquan User Guide 197 4 Creating a Processing Method Specifying Method Identification Table 70. Genesis Peak Integration parameters (Sheet 3 of 3) Parameter Description Peak Ht (%) Specifies a percentage of the total peak height. This is the minimum that a signal must be above the baseline before integration is turned on or off. This option is available only when you select the Constrain Peak Width option. Range: 0 to 100% Default multiplier: 5.0% The peak height percentage is defined as follows: Tailing Factor Specifies a value for the factor that controls how the LCquan application integrates the tail of a peak. This factor is the maximum ratio of the trailing edge to the leading side of a constrained peak and calculates the retention time of the maximum extent of the right edge of the tailing peak. This option is available only when you select the Constrain Peak Width option. Range: 0.5 to 9.0 Default multiplier: 1.0 (1.0 has no effect) 198 LCquan User Guide Thermo Scientific 4 Creating a Processing Method Specifying Method Identification Table 71. Genesis Advanced Component Options parameters Parameter Description Peak Edge Detection Chromatogram peak detection criteria using the peak signal-to-noise (S/N) cutoff value. Peak S/N Cutoff The peak edge is set to values below this defined S/N. This test assumes an edge of a peak is found when the baseline adjusted height of the edge is less than the ratio of the baseline adjusted apex height and the peak S/N cutoff ratio. When the S/N at the apex is 500 and the peak S/N cutoff value is 200, the LCquan application defines the right and left edges of the peak when the S/N reaches a value less than 200. Range: 50.0 to 10 000.0 Valley Detection Valley detection approximation method to detect unresolved peaks. Rise Percentage The percentage that the peak trace can rise above the baseline after passing through a minimum (before or after the peak). This method drops a vertical line from the apex of the valley between unresolved peaks to the baseline. The intersection of the vertical line and the baseline defines the end of the first peak and the beginning of the second peak. When the trace exceeds rise percentage, the LCquan application applies valley detection peak integration criteria. This test is applied to both the left and right edges of the peak. The rise percentage criteria is useful for integrating peaks with long tails. Range: 0.1 to 500.0 Valley S/N Specifies a value to evaluate the valley bottom. Using this parameter ensures that the surrounding measurements are higher.

When any of the qualifier ion/quantitate ion response ratios are outside of the upper or lower bounds that you specify, or if the quantitate and qualifier ions do not coelute, the LCquan application marks the analyte as Not Found in the Review All Results view in the Quantitate window. Specify the masses, target area ratios, and area ratio windows of the qualifier ions in the Ion Ratio Confirmation table of the processing method. The LCquan application displays the mass chromatograms of the qualifier and quantitate ions in the IRC Chromatogram pane. In the following example, the LCquan application divides the area of the m/z 327.1 mass chromatogram peak by the area of the m/z 309.2+267.2 mass chromatogram peak and multiplies this value by 100. If the value is less than 50% or greater than 70%, the LCquan application marks hydrocortisone as Not Found. Also, the peak maximum of the qualifier ion chromatogram must be within 0.1 minutes of the peak maximum of the quantitate ion chromatogram. m/z 309.2+267.2 m/z 327.1 50–70% hydrocortisone 0.1 minutes Thermo Scientific LCquan User Guide 225 4 Creating a Processing Method Specifying Method Calibration Specifying Method Calibration After importing the component names and calibration levels from the acquisition sequence into the processing method, use features on the Calibration page to specify the identification settings for the internal standard and target compounds.

Thermo Scientific LCquan User Guide 287 5 Creating a Processing Sequence Defining a Processing Sequence Copying an Acquisition Sequence Usually, instead of creating a processing sequence, it is more convenient to use your acquisition sequence as your processing sequence. You can do this in either of two ways: • Copying from the Acquisition Sequence History • Copy from the Acquisition Sequence Copying from the Acquisition Sequence History Use the acquisition sequence history list on the Create Sequence (edit) view to copy sequences to your sequence grid. When you have already acquired data in the workbook, the acquisition sequence or sequences that you used are listed in the acquisition sequence history list. To copy an acquisition sequence, select it from the list and drag it into the processing sequence grid. To select multiple sequences, hold down the SHIFT or CTRL keys. The LCquan application will ask if you want to replace the current sequence and if you want to overwrite the levels for matching component names. Copy from the Acquisition Sequence When an acquisition sequence already exists in the current workbook, you can use it to define the processing sequence in the following ways: • From the File > Import menu – Choose Processing Sequence > Copy From Acquisition Sequence to copy the acquisition sequence from the current workbook. – Choose Processing Sequence > Copy From Last Acquired Sequence to copy the last-acquired sequence. • Right-click anywhere in the Create Sequence (edit) view and use the commands on the shortcut menu: 288 LCquan User Guide – Choose Import Processing Sequence > Copy From Acquisition Sequence to copy the acquisition sequence from the current workbook. – Choose Import Processing Sequence > Copy From Last Acquired Sequence to copy the last-acquired sequence. Thermo Scientific 5 Creating a Processing Sequence Defining a Processing Sequence Importing a Processing Sequence Use any of these methods to import an existing processing sequence into your current workbook: • New Study Wizard When you create a new workbook, the New Study Wizard gives you the option of importing instrument methods, acquisition sequences, and processing parameters to initialize the new workbook. You can import all this data from an existing workbook, or you can import an acquisition sequence from an individual legacy file (.sld, .ipp, or .csv) or from an LCquan file (.lqn). When you import an acquisition sequence from an individual legacy file into a workbook that does not contain a processing sequence, the LCquan application uses the same sequence for the acquisition sequence and the processing sequence in the current workbook. • New Processing Sequence Wizard in the Quantitate window When you use the New Processing Sequence Wizard, you have the option to import a previously saved sequence from an individual legacy file (.sld, .ipp, or .csv) or from an LCquan file (.lqn). • Menu commands from within the Quantitate window From the Create Sequence views of the Quantitate window, choose File > Import > Processing Sequence > From File to display the Load Sequence File dialog box and import a sequence from an individual legacy file (.sld, .ipp, or .csv) or from an LCquan file (.lqn). From anywhere in the Create Sequence (edit) view, right-click and choose Import Processing Sequence > From File from the shortcut menu to display the Load Sequence File dialog box. Note The level names in the processing sequence must match those defined in the processing method: • If the calibration or quality control level names in the sequence are different from those in the processing method, the LCquan application displays the Standard Level Names Association dialog box or the QC Level Names Association dialog box. You can use these dialog boxes to associate the level names in the sequence with the level names in the processing method. • If the imported sequence contains calibration or QC levels but the processing method does not, the LCquan application displays a warning box to inform you. It then displays the Sample Type Assignment dialog box. You can change the sample type of these samples to unknown in the processing sequence or discard the samples that have these levels in the processing sequence. Thermo Scientific LCquan User Guide 289 5 Creating a Processing Sequence Editing a Processing Sequence Copying the Last Acquired Sequence You can replace the defined processing sequence with a shortened sequence that is based on the data already acquired. To update the processing sequence with the most recent list of acquired samples, do the following: 1. Choose Options > Acquisition Sequence Info to open the Acquisition Sequence dialog box. 2. To update the sequence, select Auto Update the Processing Sequence When Acquiring. If you are currently acquiring data when you select this option, a message box prompts you to update the current processing sequence with the most recent list of samples acquired. If you do not respond to the message box after five seconds, the LCquan application automatically updates the sequence. Alternatively: Right-click the sequence grid and choose Import Processing Sequence > Copy from Last Acquired Sequence from the shortcut menu. For details about the Acquisition Sequence parameters, see “Processing Data While Continuing to Acquire Data” on page 99 in Chapter 2, “Preparing to Perform Quantitative Analysis.” Editing a Processing Sequence If you already created a processing sequence, use the Create Sequence views to edit the current sequence or create a new one. • Using the Create Sequence (edit) View, you can review the sequence information and edit the information in many of the sequence columns. • Using the Create Sequence (create) View, you can associate new raw files with sample types or levels. Using the Create Sequence (edit) View When you use the LCquan application for quantitative analysis, you do not always have to create a new processing sequence. Instead, you can copy the acquisition sequence from the current workbook to use as the processing sequence or import an existing sequence from another workbook or legacy file. With these techniques, you can quickly define your processing sequence. 290 LCquan User Guide Thermo Scientific 5 Creating a Processing Sequence Editing a Processing Sequence After you copy or import a sequence, use the Create Sequence (edit) view to review the processing sequence to ensure that it is correct and, if necessary, alter the processing sequence in several different ways: • Review the processing sequence • Remove a raw file from the processing sequence • Add a raw file to the processing sequence • Change the sample type • Change a range of cells • Modify the arrangement of the processing sequence Review the processing sequence 1. To open the Create Sequence (edit) view and display the new processing sequence, click Edit. Figure 39. Create Sequence (edit) Interface 2.

Thermo Scientific LCquan User Guide 297 5 Creating a Processing Sequence Editing a Processing Sequence Table 113. Processing sequence grid column parameters (Sheet 1 of 3) Parameter Description Sample Type Displays the type of sample described by the sequence row. The sample type defines how the LCquan application processes the sample data. Each sample must be classified as one of the following LCquan sample types: • • • • FileName Unknown Blank QC (quality control) Standard Displays the name of the raw file that contains the sample data. The file name is a combination of the base file name prefix assigned to the sequence and a sequential sequence number. When the default sequence starting number 1 was not changed, the suffix number is the same as the row number of the sequence: 001, 002, and so on. When the default sequence starting number was changed to another number, the first sample has the starting number and subsequent rows in the sequence are incremented by 001. For example, if the starting number was 100, the file name for the first sample would have a suffix of 100, the second sample would have a suffix of 101, and so on. 298 LCquan User Guide Path The path in the workbook from which raw files are loaded. Sample ID Displays the sample ID for each data file. The sample ID is an alphanumeric string of characters that identifies a sample. Level Indicates the level defined for a calibration sample or quality control sample. For details about calibration or QC levels, see Chapter 4, “Creating a Processing Method.” Thermo Scientific 5 Creating a Processing Sequence Editing a Processing Sequence Table 113. Processing sequence grid column parameters (Sheet 2 of 3) Parameter Description ISTD Corr Amt Specifies an updated amount of internal standard for the corresponding sample. The default value is 0.0. For each component defined as an internal standard, a bulk adjustment factor can be applied to the base response of each internal standard defined in the processing method. When no adjustment is required, verify that a value of 0.000 is entered in the ISTD Corr Amt box. When an adjustment is required, enter the actual value of all internal standard amounts or concentrations in the sample into the ISTD Corr Amt box for the sample row or rows requiring adjustment. The new value entered must use the same units as specified in the processing method. Do not enter the units of measurement into the box. For example, for 20 ng, type 20. Dil Factor Displays the dilution factor used to prepare the sample. The valid range is 0.000 to 10 000.000. The LCquan application interprets a value of 0.000 as no dilution. Vial Pos Displays the sample’s position number in the autosampler. This column value is read-only. Inj Vol Displays the injection volume in microliters of sample to be injected. When you are using an autosampler, you can set the default injection volume in the Autosampler dialog box in the Instrument Setup window. The minimum and maximum injection volumes that you can use depends upon the Autosampler you select. The usable range is dependent upon the injection mode and might be smaller than the range displayed in the status bar. For more details, consult your Autosampler manual. Fill Down cannot be used on Inj Vol column values. Thermo Scientific Sample Vol Displays the volume of a component that has been placed in the sample. The unit for this volume is specified in the Xcalibur Processing Setup window and is included only in LCquan reports. The LCquan application does not convert units.

Only peaks with a signal-to-noise ratio greater than this value are integrated. Range: 0.0 to 999.0 Default multiplier: 0.5 Valley Detection Enabled Detects unresolved peaks with the valley detection approximation method. The LCquan application drops a vertical line from the apex of the valley between unresolved peaks to the baseline. The intersection of the vertical line and the baseline defines the end of the first peak and the beginning of the second peak. 338 LCquan User Guide Thermo Scientific 6 Processing the Raw Files and Reviewing the Analytical Results Reviewing the Calibration Curve and QCs Table 128. User Identification Settings parameters (Sheet 2 of 3) Parameter Description Expected Width (sec) This multiplier specifies an expected peak width parameter that controls the minimum width that a peak is expected to have when valley detection is enabled. With valley detection enabled, any valley points nearer than half the expected width to the top of the peak are ignored. If a valley point is found outside the expected peak width, the LCquan application ends the peak at that point. It always ends a peak when the signal reaches the baseline, independent of the value set for the expected peak width. Range: 0.0 to 999.0 Default multiplier: 0.0 Units: seconds Note Valid only when you select Valley Detection Enabled. Constrain Peak Width Constrains the peak width of a component during the peak integration of a chromatogram. You can set values that control when peak integration is turned on and off by specifying a peak height threshold and a tailing factor. Selecting this activates the Peak Ht (%) and the Tailing Factor parameters. Peak Height Specifies a percentage of the total peak height. This is the minimum that a signal must be above the baseline before integration is turned on or off. This option is available only when you select the Constrain Peak Width option.

User Identification Settings – Genesis Advanced parameters Parameter Description Report Noise As RMS or Peak to Peak Determines if the noise used in calculating S/N values is calculated using an RMS calculation or peak-to-peak resolution threshold. Rise Percentage The percentage that the peak trace can rise above the baseline after passing through a minimum (before or after the peak). This method drops a vertical line from the apex of the valley between unresolved peaks to the baseline. The intersection of the vertical line and the baseline defines the end of the first peak and the beginning of the second peak. When the trace exceeds rise percentage, the LCquan application applies valley detection peak integration criteria. This test is applied to both the left and right edges of the peak. The rise percentage criteria is useful for integrating peaks with long tails. Range: 0.1 to 500.0 Valley S/N Specifies a value to evaluate the valley bottom. Using this parameter ensures that the surrounding measurements are higher. Range: 1.0 to 100.0 Default: 2.0 Peak S/N Cutoff The peak edge is set to values below this defined S/N. This test assumes an edge of a peak is found when the baseline adjusted height of the edge is less than the ratio of the baseline adjusted apex height and the peak S/N cutoff ratio. When the S/N at the apex is 500 and the peak S/N cutoff value is 200, the LCquan application defines the right and left edges of the peak when the S/N reaches a value less than 200.

You can modify the Avalon estimates by entering your own values and clicking Add to save your Start or End Threshold. The Start Threshold depends on the RMS noise in the chromatogram. It is the fundamental control used for peak detection, so picking the best Start Threshold is essential for high-quality data collection. Units: Absolute value of peak area (counts x seconds) Bunch Factor The number of points grouped together during peak detection. This method groups several chromatographic points during integration without affecting the final area calculation of the peak. Range: 1 to 6 Note A high bunch factor groups peaks into clusters. Area Threshold Controls the area cutoff. Any peak with a final area less than the area threshold is not recorded. Format: units of area for the data Thermo Scientific LCquan User Guide 347 6 Processing the Raw Files and Reviewing the Analytical Results Reviewing the Calibration Curve and QCs Table 133. Initial and Timed Events (Sheet 2 of 2) Event Description P-P Resolution Defines how much peak overlap must be present before two or more adjacent peaks create a peak cluster. Peak clusters have a baseline drop instead of valley-to-valley baselines. This is specified as a percent of peak height overlap. Negative Peaks Automatically resets after a negative peak has been found. Tension Controls how closely the baseline follows the overall shape of the chromatogram. A lower tension traces the baseline to follow changes in the chromatogram more closely. A high baseline tension follows the baseline less closely, over longer time intervals. Units: minutes Tangent Skim Enables tangent skim on any peak clusters. By default, the LCquan application chooses the tallest peak in a cluster as the parent (solvent) and detects peaks on either side (or both sides) of the tallest peak. You can also identify which peak in the cluster is the parent. Tangent skim automatically resets at the end of the peak cluster. 348 LCquan User Guide Integrate On/Off Turns integration on or off at the set time. Shoulders On Turns on the detection of shoulders. Shoulders Off Turns off the detection of shoulders. Force Cluster On Turns on the grouping of peaks into a single peak. Force Cluster Off Turns off the grouping of peaks into a single peak.

Grid parameters (Sheet 1 of 9) Parameter Description Displayed Column parameters (currently displayed in the grid) FileName Displays the name of the raw file that contains the sample data. The file name is a combination of the base file name prefix assigned to the sequence and a sequential sequence number. If the default sequence starting number 1 has not changed, the suffix number is the same as the row number of the sequence: 001, 002, and so on. If the default sequence starting number has changed to another number, the first sample will have the starting number and subsequent rows in the sequence are incremented by 001. For example, if the starting number is 100, the file name for the first sample will have the suffix 100, the second sample will have the suffix 101, and so on. To select a new file name, select from the file options in the FileName box. Thermo Scientific LCquan User Guide 371 6 Processing the Raw Files and Reviewing the Analytical Results Creating and Reviewing Reports Table 144. Grid parameters (Sheet 2 of 9) Parameter Description Sample Type Displays the sample type defined in the sequence row. The sample type defines how the LCquan application processes the sample data. Each sample must be classified as one of the following LCquan sample types: • Unknown—A sample type that is not a Calibration Sample, Calibration Blank, Quality Control Sample, or Quality Control Blank. The LCquan application performs quantitative analysis of unknown sample types by using internal or external standards. • Blank—A sample type that contains no target components. You can add internal standard components to calibration blanks. You can include blanks in the sequence to assist in purging all residual components from the LCquan application prior to the analysis of the next sample or sample sequence. Use LCquan analysis of a blank sample to confirm that there are no residual components in the solvent system that can cause erroneous results. This is especially important during quantitation. You can expect quantitative analysis of a blank sample to result in the detection of no target compounds. • QC (quality control)—A type of sample that contains known amounts of one or more known components. QC samples are placed in the sequence so that quantitation results can be compared with known component amounts or concentrations for quality assurance purposes. The LCquan application performs quantitation on these samples using the same calibration settings as it uses on Unknown sample types. It places Quality Control Samples after Calibration Samples and before Unknown Samples in the sequence. • Standard—A sample with a known amount of calibration reference material. To change the sample type, select from the list of sample type options. The new sample type appears in the Sample Type box. Sample Name Displays the sample name that you specified when you created the sequence. Integration Type The type of integration used is displayed in the results grid but can be overridden. The three types are Method, User, and Manual Integration. When you select Method, the LCquan application uses the integration parameters embedded within the processing method. You can enter new integration parameters by right clicking the chromatogram plot and selecting User Peak Detection Settings. This sets the integration type to User. Dragging the integration control handles on the integration baseline sets the integration type to Manual. Response Area or height of the detected peak. The value stored depends on the selection made in the calibration section. ISTD Response Area or height of the detected, peak associated Internal Standard. The value stored depends on the selection made in the calibration section. 372 LCquan User Guide Thermo Scientific 6 Processing the Raw Files and Reviewing the Analytical Results Creating and Reviewing Reports Table 144.

Thermo Scientific LCquan User Guide 385 A Quantitative Analysis Overview This appendix describes some of the basic principles and terminology of quantitative analysis1and contains the following topics: Contents • About Quantitative Analysis • Considering the Variables of Quantitative Analysis by LC/MS/MS • Quantitative Analysis Techniques • Sample Types About Quantitative Analysis In some applications, such as a clinical trial, you might be seeking the maximum possible accuracy from your measurements. Time and cost of analysis are less important than achieving the highest possible standards in precision and accuracy. This process of measuring the amount of a particular component in a sample is called quantitative analysis. In other applications, such as in trace analysis, you might only want to estimate the quantity of a component. It might be sufficient to know that the component is present at a level either significantly higher or significantly lower than a defined threshold. For example, knowing whether a patient has overdosed 15 or 20 times above a prescribed limit is generally not as important as simply knowing that the limit has been exceeded. Such cases would require a rapid measurement rather than a precise one. This form of measurement is generally called semi-quantitative analysis. 1 Thermo Scientific For further information about the principles of quantitative analysis, refer to Mass Spectrometry: Principles and Applications; de Hoffman, E., Charette, J., Stroobant, V.; Wiley: New York, 1996; and Introduction to Mass Spectrometry, 3rd ed.; Watson, J.T., Lippincott-Raven: Philadelphia, PA, 1997. LCquan User Guide 387 A Quantitative Analysis Overview Considering the Variables of Quantitative Analysis by LC/MS/MS Quantitative analysis consists of the following steps: • Preparing samples • Developing a suitable chromatographic method • Calibrating the mass spectrometer’s response • Analyzing the samples • Reviewing the results This manual does not describe sample preparation and chromatographic method development. This manual assumes that you have met these important prerequisites to achieving high quality quantitative analysis. For guidance in these areas, refer to the getting started and hardware manuals for your autosampler, LC pump or MS pump, and mass spectrometer. Considering the Variables of Quantitative Analysis by LC/MS/MS The combination of liquid chromatography (LC) and mass spectroscopy (MS) sets up a unique set of considerations. If you are familiar with quantitative analysis using one or the other of these analytical tools, the information in the following topics will prove useful: • Using LC for Analyte Separation • Using MS/MS for Analyte Detection Using LC for Analyte Separation When working with LC systems, you become accustomed to developing methods for analytes of interest. These methods take into account a variety of parameters. Consider the following LC parameters for optimum separation of compounds: • Composition of stationary phase • Column diameter • Column length • Column usability over time • Solvent(s) or composition of mobile phase • Flow rates • Isocratic or gradient (ramped) solvent compositions 388 LCquan User Guide Thermo Scientific A Quantitative Analysis Overview Considering the Variables of Quantitative Analysis by LC/MS/MS Often the only measurable result of optical detectors that you can use to identify an analyte is the retention time at a specified wavelength. To quantitate compounds accurately, the compound peaks must be distinctly separated from each other in time. By carefully optimizing the LC variables listed above, you can successfully separate and detect compounds with an optical detector such as an ultraviolet (UV) or photodiode array (PDA) detector. In contrast to optical detectors, mass spectrometers can often successfully detect individual analytes even when two or more compounds coelute as a single chromatographic peak. Coeluting compounds are ionized in the mass spectrometer, and the parent or fragment ions specific to the analyte or analytes are detected and measured for quantitative analysis. Because the mass spectrometer detection is so specific, you can reduce the chromatographic resolution and shorten the run times. Using MS/MS for Analyte Detection To optimize detection of ions by MS/MS, consider the following variables when working with a mass spectrometer interfaced to an LC: • Solution chemistry and polarity of the analyte of interest • Probe selection (H-ESI, ESI, APPI, or APCI) • Collision energy to fragment parent ions inside the mass spectrometer (optimized by experiment) The LC provides a stream of analyte solution (eluate) into the mass spectrometer where the analyte is detected. You must consider the content of modifiers, salts, and contaminants in the eluate. Specifically, you must ensure that what goes into the inlet of the mass spectrometer does not suppress ionization of the compound of interest. Salt concentrations above 10 mM and strong acids and bases damage the LC column. Modifier concentrations greater than 10 mM are not usually necessary for chromatographic stability and can suppress ionization of other compounds. For best results, whenever possible, use volatile modifiers. Volatile modifiers include the following: • Acetic acid • Ammonium acetate • Ammonium formate • Ammonium hydroxide • Formic acid • Trifluoroacetic acid Thermo Scientific LCquan User Guide 389 A Quantitative Analysis Overview Quantitative Analysis Techniques Your analyte solution can contain neutral particles or ions. If the solution contains ions, the ions can carry a single charge or multiple charges. The number of charges depends on the structure of the analyte and the composition and pH of the mobile phase. Solvent systems are generally composed of organic solvents, water, and volatile modifiers. The ionization characteristics of your analyte influence your decisions about the optimum pH of your solvent system and the type of probe to use at the interface of the LC and the mass spectrometer. With the TSQ Quantum series, LTQ series, or LCQ series instruments, you can use either the H-ESI probe, the ESI probe, the APCI probe, or the APCI/APPI probe at the interface of the LC. The choice of probe depends on the class of compound that you want to analyze and, to a small extent, on the flow rate of your experiment. In general, the APCI and the APCI/APPI probes accommodate higher flow rates and molecules of a less polar nature than does the ESI probe. Refer to the introduction in the getting started manual for your mass spectrometer for what factors might influence your decision about flow rates and what probe to use for optimum transfer of ions into the mass spectrometer. After the ions are inside the mass spectrometer and the parent ions are isolated, collision energy is applied to dissociate the parent ions into product ions (MS/MS). The relative collision energy for a particular analysis depends on the structure of the compound that you are analyzing. For this reason, you optimize the collision energy on your analyte of interest in a tuning experiment. Refer to the getting started manual for your mass spectrometer for the tuning procedure that describes how to optimize the collision energy. Quantitative Analysis Techniques To carry out quantitative analysis, you must evaluate the instrument’s response to known amounts of the target component. Response is based on either the height of the chromatogram peak or, more commonly, the area under the peak’s profile (see Figure 48). In both cases, you must take into account the baseline of the detected peak. Instrument response is generally measured with several samples commonly called standards, or calibration standards. These standards must cover a suitably wide range of concentrations or amounts and must bracket the range of expected concentrations in the unknown. Responses to these standards are plotted in a graph called a calibration curve. Ideally, this curve corresponds to the equation of a straight line to ensure the highest degree of precision.2 Fitting an equation to the calibration curve with a user-specified method (for example, a least squares regression) provides a response factor—a comparative measure of the response of the mass spectrometer to a component. It is based on the amount of sample injected and the resulting peak area or peak height. The response factor gives an intuitive and quantitative measure of how responsive or sensitive the mass spectrometer is to a certain component. 2 390 LCquan User Guide Mass Spectrometry: Principles and Applications; de Hoffman, E., Charette, J., Stroobant, V.; Wiley: New York, 1996; p 162. Thermo Scientific A Quantitative Analysis Overview Quantitative Analysis Techniques Relative Intensity Figure 48. Integrated chromatographic peak Time (min) To perform quantitative analysis of samples containing unknown amounts of the target component, calculate the peak area or height and compute and apply the appropriate response to the equation derived from the calibration curve. These steps provide an estimate of the amount of the target component in the samples. The precision of the measurement depends on the quality and, to a lesser extent, the quantity of the calibration data. The detection limit of the quantitative analysis method is the lowest concentration of analyte in a sample that can be detected but not necessarily quantitated as an exact value. The lower and upper quantification limits are the lowest and highest concentrations of analytes in a sample that can be measured with an acceptable level of accuracy and precision. In an analytical method, the highest concentration calibration standard defines the upper quantification limit. The quantitative analysis technique you use determines the manner in which the response is calculated, both for generating the calibration curves and for subsequent quantitative analysis. The two basic methods are described in these topics: • Using External Standards for Quantitative Analysis • Using Internal Standards for Quantitative Analysis Thermo Scientific LCquan User Guide 391 A Quantitative Analysis Overview Quantitative Analysis Techniques Using External Standards for Quantitative Analysis An external standard is a separate sample that contains the compound of interest at a known concentration in solution. In the quantitative analysis that uses external standards, a series of standards are analyzed and a calibration curve is constructed by plotting the magnitude of the detector response as a function of the external standard concentration (see Figure 49). You analyze the unknown sample and determine the concentration by matching the magnitude of the detector response with the magnitude on the calibration curve. Using external standards is advantageous when you are analyzing various components in a sample and you can assay all compounds of interest by using a single set of external standards. Although this approach offers time- and cost-effective quantitative analysis, it cannot achieve the very highest precision and accuracy. Variations in analyte and solution stability, injection reproducibility, and matrix interference lead to lower precision levels in the external standard method than in the internal standard method. Figure 49. Calibration curve generated by using an external standard Response for unknown sample 500000 Response for target compound 400000 300000 200000 Amount [A] in unknown sample 100000 0 0 20 40 60 80 100 Amount of target compound [A] Using Internal Standards for Quantitative Analysis An internal standard (ISTD) is a component that is added to a sample to act as a response reference for one or more non-ISTD components in the sample. The concentration or amount of an ISTD in any standard or unknown sample remains constant. Because quantitative mass spectrometric analysis usually involves multiple steps, the total error in the analysis results from the accumulation of the errors at each step. In general, sample-handling errors account for a larger fraction of the total error than do mass-spectrometer errors. Fortunately, the internal standard method can reduce both sources of error. For example, internal standards can correct for variations in a component’s peak area that are caused by the following: • Injection irreproducibility • Changes in analyte solution volume 392 LCquan User Guide Thermo Scientific A Quantitative Analysis Overview Quantitative Analysis Techniques • Matrix and coeluter interference (both suppression and enhancement) • System instability • Variations in the source conditions For maximum precision, add the ISTD component as early as possible to the start of the sample work-up, particularly in those quantitative methods that require sample manipulations such as extraction, cleanup, and dilution. Because the ISTD and non-ISTD components are analyzed together, the internal standard quantitative analysis approach has the advantage that it corrects for injection and other sample handling errors. The ISTD must behave chemically in an identical or similar manner to the target compound through the extraction, cleanup, and analytical processes. You can also add the ISTD component as the last step of sample preparation prior to the sample’s use to compensate for fluctuations in the reproducibility of the sample injection. Use ISTDs in a quantitative analysis experiment as follows: 1. Analyze a series of standard solutions containing known concentrations of the target compound and ISTD, and plot the ratio of the target compound and the ISTD detector responses as a function of the corresponding ratio for the two quantities present in the solution. 2. Add a fixed amount of the ISTD to each sample prior to any manipulation, and, after preparing and analyzing the samples, obtain the quantity of the target compound present in an unknown sample from the calibration curve. Ideally, an ISTD is closely related to the target component in terms of its physical and chemical properties. It must be pure, not present in the sample, and inert toward the components of the sample. ISTD components are typically analogs, homologs, or isomers of the target non-ISTD component. An ideal ISTD is a structural or isotopically labeled analog of one of the target components. Stable isotope-labeled ISTDs act almost identically to the analyte throughout sample manipulation and with regard to ionization tendencies and fragmentation. Internal standards labeled with two or more deuterium (D) atoms are frequently used for LC/MS. There can be any number of ISTD components in a sample, but each non-ISTD component can be calibrated against only one ISTD.

The sequence represents the order of sample analysis. A quantification sequence contains: • One or more standards • One or more unknown samples For more demanding applications, you can also use optional quality control (QC) samples and blank samples. Standards A calibration standard is a sample containing known amounts of all target components. The purpose of a standard is to measure the response of the instrument to the target components so that the LCquan application can generate a calibration curve for each component. Unknowns An unknown sample is one containing unknown amounts of the target components. The LCquan application performs quantitative analysis on any sample defined as an unknown sample. 394 LCquan User Guide Thermo Scientific A Quantitative Analysis Overview Sample Types QCs A QC sample contains a known amount of one or more specific target compounds. The LCquan application places QC samples in the sequence so that it can test quantitative analysis results for quality assurance purposes. After the QC sample is analyzed, it compares the measured quantity with the expected value and an acceptability range. The quantitative analysis of a QC sample is classified as passed if the difference between the observed and expected quantities is within the user-defined tolerance. A QC sample is classified as failed if the difference between the observed and expected quantities is outside the defined tolerance. Blanks A blank sample contains no target components but might contain an ISTD when you use the internal standard quantitative analysis technique. By analyzing a blank sample, you can confirm that there are no residual components in the solvent system that can cause erroneous results.
