Abstract

A method for identifying a reagent during a process in an analysis system is disclosed. The analysis system comprises a liquid chromatograph and a mass spectrometer. The method comprises providing a reagent, adding at least one chemical substance to the reagent with a concentration being below a detection level of the mass spectrometer, enriching the chemical substance within the liquid chromatograph to a concentration above the detection level of the mass spectrometer, processing the reagent together with the enriched chemical substance by means of the analysis system, and identifying the reagent based on a detection of a substance detection signal of the mass spectrometer representing the chemical substance.
