摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a measurement sample for MALDI mass spectrometry, which can arrange two or more kinds of matrices in one sample when performing mass spectrometry by MALDI. SOLUTION: In a base material on which a matrix used for preparing a measurement sample for MALDI mass spectrometry is arranged on the surface, a laser beam is irradiated on the surface of the base material on the side opposite to the side on which the matrix is arranged. This is a method for preparing a measurement sample for MALDI mass spectrometry, which comprises flying the matrix from the substrate and arranging the matrix at a predetermined position of a sample to be subjected to MALDI mass spectrometry.
