Claim 6:
7. A mass spectrum processing method, comprising:
generating, by at least one processor, a chromatogram based on a mass spectrum array formed from a plurality of mass spectra arranged on a time axis;
identifying, by at least one processor, for each mass spectrum, a plurality of representative peaks included in a mass spectrum constituting the mass spectrum array;
extracting, by at least one processor, the plurality of representative peaks included in the mass spectrum;
identifying, by at least one processor, a representative peak array formed from the plurality of representative peaks included in a mass spectrum, for each mass spectrum, based on a mass spectrum array formed from a plurality of mass spectra arranged on a time axis;
plotting, by at least one processor, a plurality of graphs reflecting temporal changes of the plurality of representative peaks based on a plurality of representative peak arrays identified from the plurality of mass spectra;
generating, by at least one processor, a trend chart formed from the plurality of graphs reflecting temporal changes of the plurality of representative peaks based on the plurality of representative peak arrays identified from the plurality of mass spectra;
displaying, by at least one processor, the chromatogram, the trend chart, and mass spectrum stability information generated from the trend chart;
determining, by at least one processor, a mass spectrum stable period by analyzing the trend chart based on the mass spectrum stability information; and
detecting, by at least one processor, peaks in the chromatogram while distinguishing the peaks from noise based on the mass spectrum stable period.
