Add Group

Adds or updates a group of peaks selected in the calibration standard into the calibration. To use this command, peak groups must first be defined in the chromatogram, for more details see Add Group topic. Groups are identified by the corresponding letter.

The Calibration - Add Group command or the corresponding icon moves the cursor to the graph of the calibration standard, where the desired group should be selected. Use the Esc key to exit the command at any time.

• On All Signals / On Active Signal: Determines whether the group response is added on all signals or only on the active signal. Group identification is shared across all signals.
• Automatic Calibration: When a new standard chromatogram is opened, Add Group always assigns the group to the first empty calibration level. As long as groups are added from the same chromatogram, they are added to the last active level if they do not already have added responses here. A new calibration level is created if Add Group is used on a group that is already present on the last active level (even within the same chromatogram) or when a different chromatogram is opened.
• Automatic Recalibration: The group is added or updated at the current level, with further adjustments possible later.
• Manual Calibration / Recalibration: The (Re)calibrate Group dialog opens after selecting the group, allowing modification of previously entered data.
