Mass spectrum analyzer, mass spectrum analysis method, mass spectrometer, and program

摘要

PROBLEM TO BE SOLVED: To provide a mass spectrum analysis device capable of accurately estimating an elemental composition from a mass spectrum.SOLUTION: A mass spectrum analysis device 40 estimates a composition from mass spectral data acquired by applying mass analysis to a sample. The mass spectrum analysis device includes: a peak selection unit 412 for selecting a plurality of analysis object peaks to be analyzed from the mass spectral data; a composition estimation unit 414 for estimating an element composition for each of the plurality of analysis object peaks; and an extraction unit 416 for extracting a combination of molecular ions and fragment ions from an estimated result of the elemental composition by the composition estimation unit 414.SELECTED DRAWING: Figure 1
