Here we describe how to add group defined in the calibration standard into the calibration. For more information on how to define a group and add peaks in it, see Adding a peak to a group.
Grouped peaks in the calibration are evaluated together which is suitable for related compounds that produce separate but closely eluting peaks that should be treated as one component in quantification and reporting.
If you only need to sum the amounts of already calibrated peaks for reporting purposes, see Creating a custom result group.
- Open the Calibration window with the desired calibration file and standard file in which at least one group is already defined.
- Use the Calibration - Add Group command or the Add Group icon
.
Note:
If the calibration standard is hidden (e.g., by resizing the Calibration window or expanding the Compound Summary Table), the Add Group command and icon will not be active.
- The cursor is locked to the calibration standard graph. Choose the desired group by clicking on it in the graph.
New row will be inserted in the Calibration Summary Table. Here you can change the Group name in the Compound name cell and set other parameters in their respective fields. The group name will be also displayed in the Result Table of the Chromatogram window if the calibration is linked.
