Abstract
A peak tracking device includes a chromatogram acquirer that acquires chromatograms based on measurement data obtained by providing an analysis device with analysis condition data, and a peak associator that associates each peak included in each chromatogram with one another. The peak associator includes a peak spectrum extractor that extracts peak spectral data being a spectrum derived from a peak from measurement spectral data acquired from each measurement data, an orthogonal spectrum extractors that extracts, from the measurement spectral data, spectral data orthogonal to a dominant component among components of the peak spectral data, and a similarity determiner that associates each peak with one another based on similarity of the spectral data extracted from the orthogonal spectrum extractor.
