Mass spectrometry data analysis method and imaging mass spectrometer

Abstract

An imaging mass spectrometer according to the present invention includes: a measurement unit to acquire data by performing mass spectrometry on each of a plurality of micro regions in a measurement region on a sample; a narrowing unit to perform a process of narrowing a peak width with respect to each peak detected in each of a plurality of profile spectra based on the data individually obtained in the plurality of micro regions to be averaged or summed; a spectrum calculation unit to obtain an overall mass spectrum by averaging or summing the plurality of mass spectra processed by the narrowing unit; a peak selection reception unit to display the overall mass spectrum and receive an instruction from a user to select a peak on the mass spectrum; and an image creation unit to create a mass spectrometry image corresponding to the peak received by the peak selection reception unit.
