Description:
Peaks may be grouped and then be calibrated together. You may assign the group any name, whilst it is recommended to use the name of the group's most "important" member. The members must not necessarily succeed one another.
During calibration (not during peak detection), the peak group is treated as one non-resolved peak: The calibration constants of the amount value and the area sum of all peaks (if the selected Integration Type is area) being part of the group are calculated. The calibration curve, therefore, is identical for all peaks.
During integration, the amount/concentration values for each peak are calculated individually for each peak from its area.
If a peak belongs to a user-defined group, the Group report peak variable indicates the group's name. In addition to the user-defined peak groups, two pre-defined groups are available:
1. The group of all unidentified peaks without explicit group entry (empty group)
2. The group of all identified peaks without explicit group entry (empty group)
Define all other groups of identified peaks on the Peak Table tab page in the QNT Editor. For unidentified peaks, the group defined in the Unidentified Peaks dialog box on the General tab page in the QNT Editor is indicated if the peak appears in the corresponding time interval.
Tip:
The Integration and Calibration types must be identical for all peaks within a peak group.
