PEAK TRACKING DEVICE, PEAK TRACKING METHOD, AND PEAK TRACKING PROGRAM

摘要

This peak tracking device comprises a chromatogram acquisition unit (203) for acquiring chromatograms (CG) on the basis of measurement data (MD) obtained by applying analysis condition data (AP) to an analysis device (3) and a peak association unit (205) for associating the peaks included in the chromatograms. The peak association unit comprises: a peak spectrum extraction unit (206) for extracting, from measured spectrum data (MSD) acquired from each set of measurement data, peak spectrum data (PSD) consisting of spectrums originating from peaks; an orthogonal spectrum extraction unit (207) for extracting, from the measured spectrum data, spectrum data (RSD) that is orthogonal to dominant components from among the components of the peak spectrum data; and a similarity determination unit (208) for associating the peaks according to similarities between spectrum data extracted by the orthogonal spectrum extraction unit.
