Abstract
In a mass spectrometry method for performing a qualitative and/or quantitative determination of an analyte compound contained in a sample, using a mass chromatogram acquired for one or a plurality of ions selected as a reference ion from the ions produced from the analyte compound, the present method includes the steps of: setting one or a plurality of reference-ion candidates for each of the one or a plurality of reference ions; acquiring a mass chromatogram of the sample for each of the set reference-ion candidates; calculating a shape similarity between a peak appearing at a predetermined position on the mass chromatogram and a preset model peak; and designating, as the reference ion, a reference-ion candidate corresponding to a peak having the shape similarity equal to or higher than a predetermined value.
