Abstract:
1. A chromatograph mass spectrometric apparatus for separating a plurality of components of a sample over time by a column of a chromatograph portion and introducing the respective components to a mass spectrometric portion to successively subject to mass spectrometry, the chromatograph mass spectrometric apparatus comprising: a) a preparatory adjusting section for adjusting various parameters of the mass spectrometric portion by constituting a target by a predetermined standard spectrum for a standard sample while acquiring a mass spectrum of the standard sample by introducing the standard sample to the mass spectrometric portion; b) an adjusting sample analyzing section for introducing a predetermined adjusting sample including a substance a mass spectrum of which is known to the mass spectrometric portion and acquiring a mass spectrum for the substance of the adjusting sample in a state of being adjusted by the preparatory adjusting section; c) an information modifying section for modifying the predetermined standard spectrum for the standard sample based on a difference between a mass spectrum for the adjusting sample actually provided from the adjusting sample analyzing section and a predetermined standard spectrum of the adjusting sample; and d) a final adjusting section for adjusting the various parameters of the mass spectrometric portion by constituting a target by a modified standard spectrum provided from the information modifying section while acquiring a mass spectrum by introducing the standard sample to the mass spectrometric portion.
