Chromatographic data processing apparatus, chromatographic data processing method and chromatographic analyzer

摘要

The present invention is directed to a chromatographic apparatus capable of facilitating curve fitting using a nonlinear least square method for a chromatogram having a plurality of overlapping peaks. The features of the present invention for achieving the purpose are chromatographic methods in a chromatographic data processing apparatus in which the sample to be measured is separated by a column and the chromatographic data is obtained by detecting the separated sample For any time region where there are multiple peaks, fitting processing is performed for each peak from the earliest of the time domain or the slow in the time domain, and the peak is reduced from the chromatogram in the optional time domain By calculating, the plurality of peaks of the chromatogram are resolved. As a result, the peak can be easily decomposed only by defining a set of conditions for a chromatogram having a plurality of overlapping peaks, and a peak peak of more than three components.
