Add Existing

Updates peaks and peak groups that are already present in the calibration using the data from the calibration standard, updating their retention time (if enabled in Calibration Options) and filling in Response. Unlike Add All, this command does not introduce new compounds to the calibration. If no peaks are present in the calibration, the command is disabled.

• On All Signals / On Active Signal: Determines whether Responses are updated on all signals or only on the active signal in the Calibration Summary Table. Peak identification is shared across all signals.
• Automatic Calibration: All matching compounds are updated in the calibration, and Responses are assigned to the first empty available calibration level, regardless of the selected level. The selected level then automatically switches to the newly filled one.
• Automatic Recalibration: Compounds are recalibrated at the current level, with further adjustments possible later.
• Manual Calibration or Recalibration: The (Re)Calibrate Peak or (Re)Calibrate Group dialog appears for direct data verification and adjustments.
