To identify a compound of a chromatogram in GC, there are 2 techniques: mass spectrometry and retention indices. These solutions can be complementary by bringing a confirmation for a more precise identification.

GC-LC CONCORDANCE allows the standardization of a chromatogram by using the conversion of retention time with Kovats retention indices. The calibration with Alkanes will be made internally or externally according to the nature of the sample. The identification of the compounds of the chromatogram will be possible by using the libraries of indices linked to the nature of the columns.

A double click on the peak, and the name of the compound will be displayed. Another possibility of the software is to search in the library according to the property of the product or its C.A.S. number.  Libraries can be enriched by supplementary data or be created at will.
