MASS ANALYSIS DATA PROCESSING DEVICE, MASS ANALYSIS SYSTEM AND MASS ANALYSIS DATA PROCESSING METHOD

摘要

To provide a mass analysis data processing device, a mass analysis system and a mass analysis data processing method that can analyze a repetitive structure etc., of a sample from complicated mass spectral data many peaks of which are observed.SOLUTION: A mass analysis data processing device 10 comprises a data processing part 2c which generates a peak list and a computation part 11 provided at the data processing part 2c. The computation part 11 calculates differences d in mass between all peak data from a peak list and intensity ratios y as ratios of intensities I each between two peak data used to calculate a difference d so as to generate difference-intensity ratio data consisting of the differences d and intensity ratios y. Further, the computation part 11 retrieves difference-intensity ratio data having a difference d included in a section, calculates the total of intensity ratios y of retrieved difference-intensity ratio data, and calculates difference-intensity ratio distribution data consisting of the section of the difference and the total of the intensity ratio y.SELECTED DRAWING: Figure 3
