Abstract:
A chromatogram analyzer which analyzes a chromatogram obtained by applying a sample containing n analytes (wherein n is a natural number of at least 2) to chromatography to detect peaks attributable to the n analytes, wherein the analyzer comprises:a first storage means which stores m search sets each containing n non-overlapping peak detection zones which are defined by individual peak detection starting times and peak detection ending times (wherein m is a natural number of at least 2, and each peak detection zone for one analyte in an arbitrary search set overlaps with the peak detection zone for the same analyte in another search set), a second storage means which stores a chromatogram of the sample, a first arithmetic means which detects a peak, if any, within the peak detection zone for each of the n analytes in each search set and, if a peak is detected, matches the detected peak with the corresponding analyte, and if no peak is detected, matches no peak with the analyte to obtain identical or different peak identification results in the m search sets, and a second arithmetic means which selects one of the m peak identification results obtained by the first arithmetic means.
