Summary:In a mass analysis data analyzing apparatus, centroid data is used as mass spectrum data to be analyzed. First, peaks on the centroid data are specified in order of intensity as a standard peak for identifying an isotopic cluster. The isotopic cluster is detected by comparing an emerging pattern of peaks near the standard peak and an emerging pattern of peaks of an expected isotopic cluster in the case where each valence is assumed. The valence of the determined isotopic cluster is set as the valence of the peaks belonging to the isotopic cluster, and the peak at the forefront of cluster is selected as a monoisotopic peak. With such a mass analysis data analyzing apparatus, it is possible to determine the valence of each peak and identify the monoisotopic peak in a mass spectrum.
