GC-LC CONCORDANCE allows to directly compare chromatograms with Kovats retention Indices in a single operation and by an internal or external calibration.

It’s now possible to keep the precision of the index calculated on the sample, without the constraint of resetting the instrument by regular injection of alkanes. Indeed, retention time shifts on the sample is recalculated with the precise indices kept on the reference.

A specific mathematical algorithm allows to recalculate Kovats retention indices on the sample without needing to recalibrate the instrument.
