Abstract
Before executing a search for optimal correspondence relationship with a coarse-to-fine DP (dynamic programming) algorithm using time information of peaks appearing in a chromatogram as input data, a simplified linear correction is executed based on detection of start point and end point of the section in which the peaks are present. It is sufficient to correct only nonlinear time deviations in coarse-to-fine DP, and the space to be searched is thus narrowed down. In addition, in coarse stage DP, the number of pieces of data to be processed is reduced by selecting peaks based on peak intensity. Between coarse stage DP and fine stage DP, local inappropriate matching is eliminated by performing filtering processing in accordance with trend of time deviations over the entire chromatogram. The space to be searched in fine stage DP becomes narrow, which reduces the number of candidates to be searched and shortens the calculation time.
