Abstract
(EN) MS analysis, MSanalysis, . . . , MSanalysis for peptide mixture are sequentially executed to obtain respective mass spectra (S). At this time, an analysis in which precursor ion is changed or a different cleavage condition is set for the same precursor ion is performed plural times to put together peaks appearing in mass spectra that are obtained respectively. After the number of peaks is increased, a useful peak is extracted using commonality and complementarity of the peaks of MSspectrum and MSspectrum and classification is performed for each type of peaks extracted to obtain an appearance frequency for each classification (S, S). An evaluation score on whether the extracted peak is a product ion and on a terminal is calculated based on reliability and appearance frequency that are obtained in advance (S). The evaluation score is used in estimating sequence with the use of the extracted peak to decide and output, for example, the priority of sequence candidates (S, S).
