Abstract:
1. A mass spectrometry data analysis method for analyzing data collected by executing mass spectrometry on each of a plurality of micro areas set in a two-dimensional region of a sample by a mass spectrometry device, the method comprising: a) a peak detection step in which peak information including the intensities and mass/charge ratios of peaks is collected by executing peak detection processing on mass spectrum data obtained for each of said plurality of micro areas by a processor; b) an intensity standardization step in which the peak information for each micro area obtained in said peak detection step is collected and the intensity values of each micro area are standardized so that the spatial intensity distributions can be compared for each mass/charge ratio for all of the peaks by the processor; c) a clustering execution step in which the mass/charge ratios that are made to correspond to the spatial intensity distributions are classified into a prescribed number of clusters by using the clustering of the spatial intensity distributions of each mass/charge ratio after standardization by said intensity standardization step by the processor; and d) an identification step in which the mass/charge ratios of ions derived from the same substance are identified using at least differences in a plurality of mass/charge ratios classified into the same cluster by the processor.
