摘要

This mass spectrometry device evaluation method comprises: subjecting an ester of phthalic acid to mass spectrometry by a mass spectrometry device and detecting a plurality of ions generated by a dissociation of the ester of phthalic acid; and acquiring, on the basis of the intensity ratios of the plurality of ions detected, information on whether or not the mass spectrometry device is in a state that is appropriate for carrying out analyses.
