Abstract
A method for evaluating a mass spectrometry device includes: by a mass spectrometry device, performing mass spectrometry of an ester of phthalic acid and detecting a plurality of types of ions produced by dissociation of the ester of phthalic acid; and obtaining information concerning whether the mass spectrometry device is in a state suitable for analysis, based on a ratio of intensities of the plurality of types of ions detected.
