As gas chromatography/infrared spectrometry (GC/IR) becomes routinely available, methods must be developed to contend with the large amount of data produced. We demonstrate computer methods that can be used to determine the proper ranges of frequencies within which characteristic patterns of absorbances for a given functional group can be found. The methods can be applied to Chemigram calculations for selecting aromatic compounds from collected GC/IR data. The computer acts as a functional-group selective detector.
