1. A peak tracking device comprising:
a chromatogram acquirer that acquires chromatograms based on a plurality of measurement data obtained by providing an analysis device with a plurality of analysis condition data; and
a peak associator that associates each peak included in each chromatogram with one another,
wherein 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 extractor 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 by the orthogonal spectrum extractor, and
wherein the dominant component is one of a first principal component among spectrums obtained by performing singular value decomposition of the peak spectral data and an average value in a time direction of the peak spectral data.
