PeakWidth is defined by IRDI as ABQ022#001 which states “width of a chromatogram peak in time units, measured at 10% of peak height”.
PeakHeight is defined by IRDI as ABQ023#001 which states “magnitude of a Process GC output signal in units defined by the manufacturer, measured from the peak tip perpendicular to the baseline”.
PeakArea is defined by IRDI as ABQ042#001 which states “integral of the area under the output peak of a chromatogram signal in units defined by the manufacturer”.
TailingFactor is defined by IRDI as ABQ033#001 which states “asymmetry of a substance peak in a chromatogram expressed as the ratio of the back part to the front part of the peak, referred to the peak maximum, at 10 % peak height above the baseline”.
ExpectedRetentionTime is defined by IRDI as ABQ034#001 which states “anticipated time a component needs between injection into the column and detection of the peak”.
ActualRetentionTime is defined by IRDI as ABQ035#001 which states “measured time a component needs between injection into the column and detection of the peak”.
InjectionTime is defined by IRDI as ABQ006#001 which states “time stamp of sample injection to the chromatograph”.
ComponentName is defined by IRDI as ABQ045#001 which states “name of the medium”.
