Peak extraction method and peak extraction device

摘要: PROBLEM TO BE SOLVED: To improve accuracy of peak extraction in waveform data and correlation peaks derived from the same molecule. SOLUTION: A is extracted single data. domain four kinds different internal parameter values detected, an inclusion level determined based on a structure detected relative to each 1-4. The shows reliability as 'likeness peak' existing domain. An m/z axis divided into fine sections, total levels included section calculated, many reliable plurality by performing such processing, result expressed curve, thereby acquire density curve. grouped range exceeding some threshold L used base, Peaks are grouped. group.
