Group Calibration - Agilent Technologies 8453 Operator's Manual

Group Calibration

Group calibration can be applied for compounds where the individual
concentrations are not known but the sum of concentrations for a group of
compounds is known. An example are isomers. Complete compound groups
are calibrated. The following formulae are used:

For compounds within a compound group we assume equal response factors:
Therefore the concentration of a compound within a compound group is
calculated as follows:
