Abstract
For a low-cost, high-accuracy tuning of the voltages applied to electrodes in a mass spectrometer, a chromatograph mass spectrometer () includes: a medium supplier () which supplies a medium as a mobile phase or carrier gas; a passage () which introduces, into the mass spectrometer, the medium supplied from the medium supplier; an ionizer () which ionizes the medium together with a substance coming from a member forming the passage into the medium; a measurement executer () which performs a mass separation and a measurement of a specific ion, using multiple measurement conditions which differ from each other in the value of voltage applied to at least one electrode included in one or more electrodes in the mass spectrometer; and a voltage value determiner () which determines the value of voltage applied to each electrode so that the intensity of the ion satisfies a predetermined criterion.
