PROCÉDÉ DE SPECTROMÉTRIE DE MASSE À DÉSORPTION/IONISATION LASER ASSISTÉE PAR MATRICE

摘要

The present invention relates to a matrix-assisted laser desorption ionization mass spectrometry method and, specifically, a mass spectrometry method according to the present invention comprises the steps of: acquiring mass spectrums of an analyte by performing matrix-assisted laser desorption ionization of the analyte, wherein detection spectrums, which are the mass spectrum of the analyte, and each of which is acquired using each of two or more matrixes different from each other; and removing, from each detection spectrum, peaks of a corresponding matrix to obtain a matrix-removed spectrum, and then acquiring a corrected mass spectrum of the analyte on the basis of matrix-removed spectrums for each of different matrixes.
