ISTD ID# If an internal standard calibration will be performed, enter
the ID # for the internal standard peak for this compound.
The ID # refers to the peak ISTD. ID # from the
Peaks/Groups table. If the ISTD. ID # is unknown, the
information can be added in the peak table later.
Ref ID# Enter retention time reference peak ID # to be used for this
peak. The Ref ID # refers to the peak Ref. ID # from the
Peaks/Groups table. If the Ref. ID # is unknown, the
information can be added later in the peak table. Reference
peaks are used to locate calibrated peaks when
chromatographic conditions change such that retention
times shift.
Retention time window Select either Relative or Absolute Retention time
window.
The Relative option is based on a percent of the expected
retention time of the peak.
The Absolute option is based on a specified value.
The retention time window compensates for slight
deviations from the expected retention time.
