Abstract
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 a mass spectrum of an analyte by performing matrix-assisted laser desorption ionization of the analyte, wherein a detection spectrum, which is the mass spectrum of the analyte, is acquired using each of two or more matrixes different from one another; and removing, from each detection spectrum, a peak of a corresponding matrix to obtain a matrix-removed spectrum, and then acquiring a corrected mass spectrum of the analyte on the basis of a matrix-removed spectrum for each of different matrixes.
