Title:
マススペクトル処理装置及び方法
Document Type and Number:
Japanese Patent JP7167112
Kind Code:
B2
Abstract:
A first peak list (54) is generated based on a mass spectrum of a first polymer sample, and a second peak list (56) is generated based on a mass spectrum of a second polymer sample. Based on the first peak list (54) and the second peak list (56), a numerical value array (a differential value array, a ratio array) showing a difference between the peak lists (54, 56) is calculated. Based on the numerical value array and a correlated m/z array corresponding to the numerical value array, a KMD plot (64) and an RKM plot (66) are generated as a difference plot.
