Patent ID: 10290481

Abstract:
A mass spectrometry data analysis method for analyzing a specimen having a composition where two different reference chemical structures A and B that are each repeated, includes acquiring exact mass information of each peak in a mass spectrum of the specimen by mass spectrometry, acquiring Kendrick mass defect information DA and DB where a decimal number part has been extracted from mass information obtained by performing Kendrick mass conversion computation processing on exact mass information of each peak, acquiring mass defect information dB and dA where a decimal number part has been extracted from mass information of B based on A and A based on B of the reference chemical structures A and B, calculating nA=DB/dA,nB=DA/dB  regarding DA, DB, dA, and dB, and obtaining degree-of-polymerization information nA and nB, and displaying plots corresponding to each peak on two-dimensional coordinates where nA and nB are axes.
