Although identification of compounds in chromatography is performed by mass spectrometry, many laboratories still use the identification of compounds in chromatograms by retention time. An Excel file is used. It includes at least retention times (RT) and the names of each compound used in a column and chromatographic data. The use of this information is long and laborious.

GC-LC CONCORDANCE converts these data and recomposes a chromatogram which will be used as a reference.

Now, you only have to match in three clicks 2 or 3 known peaks on the sample chromatogram.
The software will then calculate the equation of the variability of retention time due to the degradation of the column to match and thus identify the set of components of the sample.

This complete treatment does not require more than 30 seconds with a printout of the report to identify peaks present in the sample.
