Mass spectrometry - a data processing apparatus and mass spectrometry - a data processing method

摘要

A mass spectrometry - a data processing apparatus includes a data analysis unit, which a mass spectrum of each individual one of the analysis - target areas within a two-dimensional area on a sample set processed. The data analysis unit, a plurality of mass spectra which are each provided with position information of a corresponding one of the analysis - target areas; generates an average mass spectrum, which an average of the large number of spectra obtained; the mixture is extracted for each range, by comparing the number of spectra obtained with one another a highest tip and generates a by the extracted highest peaks is formed within the maximum mass spectrum; generates a a thickness ratio of the average mass spectrum, which indicates the maximum mass spectrum starches ratio spectrum; and selects a tip in a region of a for the starches ratio spectrum and delivers a set threshold from the tip to mass range containing.
