Claim 7:
8. A computer program product comprising a non-transitory storage medium including one or more instructions that, when executed by at least one processor, cause the at least one processor to:
generate a chromatogram based on a mass spectrum array formed from a plurality of mass spectra arranged on a time axis;
identify for each mass spectrum, a plurality of representative peaks included in a mass spectrum constituting the mass spectrum array;
extract the plurality of representative peaks included in the mass spectrum;
identify 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 s time axis,
plot 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;
generate 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;
display, the chromatogram, the trend chart, and mass spectrum stability information generated from the trend chart;
determine a mass spectrum stable period by analyzing the trend chart based on the mass spectrum stability information; and
detect peaks in the chromatogram while distinguishing the peaks from noise based on the mass spectrum stable period.
