Peak Matching Rules
Peak Matching Rules
The following rules apply to the peak matching process:
• if a sample peak falls within the peak matching window of a component
peak from the calibration table, the peak is given the attributes of that
component,
• if more than one sample peak falls within the peak matching window, then,
the peak closest to the expected retention/migration time is identified as
that component,
• if a peak is a time reference or internal standard, then the largest peak in
the window is identified as that component,
• if peak qualifiers are also used then the peak ratio is used in combination
with the peak matching window to identify the component peak,
• if the peak is a qualifier peak, the measured peak closest to the main peak
of the compound is identified, and
• if a sample peak does not fall in any peak matching window, it is listed as an
unknown component.
