Abstract
The results of mass spectrometry are compared; correspondences are established between individual components contained in different samples; the results of establishment of correspondences are checked; and varying components are extracted. At least two samples are compared with respect to the ion intensity corresponding to retention times and mass-to-charge ratios obtained by chromatography-mass spectrometry on the samples having a plurality of components. In ion groups observed as mass spectra, a correspondence between the retention times at which the same component is supposed to be observed is established by determining coincidence between the mass-to-charge ratios and determining that the ion intensity fall within a designated variation.
