Abstract:
1. A mass spectrometry system, comprising: a mass spectrometer which mass-analyzes an ionized analyte; and an information processor, wherein the mass spectrometer has a function of selectively fragmenting a parent ion having a particular m/z which appears in a mass spectrum and a function of mass-analyzing the fragment ions resulting from fragmentation of the parent ion, wherein the information processor has a fragment ion combination processing section, which receives information on a parent ion and a plurality of fragment ions resulting from fragmentation of the parent ion, and which makes a combination of the fragment ions reconstructing the mass of the parent ion by adding masses of the fragment ions, and also has a function of instructing the mass spectrometer to fragment and mass-analyze the fragment ions contained in the combination of the fragment ions, and wherein the fragment ion combination processing section makes the combination of the fragment ions, which meets the following equation (1): where: m is a mass of the parent ion; m
