Abstract
A peak tracking device includes a chromatogram acquirer that acquires chromatograms based on measurement data pieces obtained from measurements by an analyzer in accordance with analysis condition data pieces, a score calculator that calculates score data based on a belonging probability, the probability being calculated for each peak appeared in each chromatogram to belong to one of substances included in a sample, and a score displayer that displays on a display the score data calculated by the score calculator.
Claims5
A chromatogram analysis support program being executed by a processor provided in a computer to cause the computer to perform steps of:
- providing first and second analysis condition data pieces having different parameters to an analyzer, and acquiring first and second chromatograms by analyzing a same sample including first and second substances from the analyzer;
- identifying retention times of first and second peaks included in the first chromatogram;
- identifying retention times of third and fourth peaks included in the second chromatogram;
- performing, from the retention times of the first to fourth peaks and values of the parameters, a regression analysis of retention time of the first to fourth peaks to estimate retention time changes for each of the first and second substances, and
- calculating first and second belonging probabilities indicating to which of the first and second substances each of the first to fourth peaks belongs, wherein the first and second belonging probabilities are calculated from estimated retention times of the respective peaks obtained by the regression analysis;
- and
- displaying the first or second belonging probability on a display or outputting the first or second belonging probability.
