CA 2596381

The invention relates to a method and device for analyzing a sample containing a number of substances. The method comprises the following steps: recording one or more mass spectra (mass spectra data D) of the sample (P); deconvoluting the mass spectra in a first evaluating device (A), which assigns the chromatographic peaks (a) and their associated deconvoluted mass spectra of one substance at a time based on the correspondence with a reference spectrum of the substance, and/or determining the intensity of the obtained peaks of the ions of the mass spectra in an evaluating device (B), which assigns the chromatographic peaks (b) of the ions and their associated mass spectra based on the correspondence of selective ions and their retention time ranges of the peaks (b) with the reference values of the substance predetermined for a substance, and verifying the assignments in a validating device (V).

La présente invention concerne un procédé et un dispositif pour analyser un échantillon contenant plusieurs substances, le procédé comprenant les étapes suivantes: acquisition d'un ou de plusieurs spectres de masse (données de spectre de masse D) de l'échantillon (P); déconvolution des spectres de masse dans un premier dispositif d'évaluation (A) qui associe les pics chromatographiques (a) et leurs spectres de masse correspondants résultant de la déconvolution, respectivement à une substance, en conséquence de la correspondance avec un spectre de référence de la substance; et/ou détermination de l'intensité des pics obtenus des ions des spectres de masse, dans un dispositif d'évaluation (B) qui associe les pics chromatographiques (b) des ions et leurs spectres de masses correspondants, en conséquence de la correspondance d'ions sélectifs et de leurs intervalles de temps de rétention des pics (b), aux valeurs de référence d'une substance, prédéterminées pour cette substance; et vérification des associations dans un dispositif de validation (V).
