First, normal calibration is executed by introducing a standards sample to an MS portion, thereafter, an adjusting sample is introduced to a GC portion, and a mass spectrum is acquired by executing mass spectrometry by the MS portion with regard to an object substance separated by a column. A data processing portion compares a measured mass spectrum and a standard spectrum and modifies a standard spectrum constituting a target in executing calibration by using a standard sample from the result. The standard spectrum modified in this way is reflected with an error factor of a dispersion in a purity of the standard sample or the like and therefore, when recalibration of the MS portion using the standard sample is executed by constituting a target by the modified standard spectrum, a difference among apparatus is resolved.
