Peak Qualifiers
both measured at the retention time of the compound.
The QualTolerance parameter defines the acceptable range of the qualifier
ratio, for example, ± 20%.
The tolerance can be set in the calibration table user interface (Identification
Details) and is an absolute percentage.
For multilevel calibrations, the ChemStation calculates a minimum qualifier
tolerance based on the measured qualifier ratios at each calibration level. The
minimum qualifier tolerance is calculated using the following equation:
where q

is the measured qualifier ratio at level i.
