GC-LC CONCORDANCE software improves drastically the reliability of compounds identification in perfume products especially with mass data usage (GC-MS).

In “SCAN” mode, the mass spectrometer (MS) will generate a chromatogram in which each peak can be identified.

This identification is not detailed and has to be considered with great caution. Indeed, in the list of products available for each compound, the first proposal of the name of the product is not necessarily the correct one. The real identity of the chemical product may appear only at the 5th place in the MS library proposal.

If you have to repeat this analysis, the uncertainties of identification will be on every measure. This method is not reliable.

Using GC-LC CONCORDANCE software with mass spectrometry will greatly improve the reliability of the identification of compounds from a chromatogram.

The identification on a product will be done once by correcting errors of proposals provided by MS.
Once the correct identification of all compounds of the product is made, the chromatogram, well documented this time will be used by GC-LC CONCORDANCE software .


This chromatogram can then be used as the reference chromatogram for several months or years! The analysis report will be reliable on the identification of outgoing compounds or on missing components of the sample to be controlled.
