Provided is mass spectrometry including applying a laser beam to a matrix dot disposed on a surface of a measurement sample. One of: a laser spot appearing in the measurement sample when the laser beam is applied to the matrix dot; and the matrix dot, is completely enclosed in the other.

Mass spectrometry

A method for preparing a measurement sample for MALDI mass spectrometry, the method including applying a laser beam to a base including a matrix used for preparing the measurement sample for MALDI mass spectrometry, the matrix being disposed on a surface of the base, in a manner that the laser beam is applied to a surface of the base opposite to the surface including the matrix, to make the matrix fly from the base to be disposed at a predetermined position of an analyte of MALDI mass spectrometry, wherein the base includes a laser energy absorbable material, and wherein laser energy of the laser beam has a wavelength of 400 nm or longer.
