DATA PROCESSING SYSTEM AND DATA PROCESSING METHOD FOR CHROMATOGRAPH

摘要

A data processing system including a sensitivity coefficient holder for holding a value R of a sensitivity coefficient for a wavelength λ1 belonging to one peak in a spectrum of a first component and a second wavelength λ2 belonging to the same peak and having a lower intensity than λ1, the value R defined using the ratio of the peak areas or similar information of two chromatograms respectively obtained at the two wavelengths; a chromatographic detector for spectroscopically analyzing sample components exiting from a component-separating column and for measuring an intensity at the second wavelength λ2 of the spectrum of the first component and an intensity at a wavelength λ3 of a spectrum of a second component at each point in time; and a concentration ratio calculator for calculating the ratio of concentration between the first component and the second component.

1. A data processing system for a chromatograph, comprising:
a) a sensitivity coefficient holder for holding a value R of a sensitivity coefficient for a wavelength λ1 belonging to one peak in a spectrum of a first component and a second wavelength λ2 belonging to the same peak and having a lower intensity than λ1, the value R defined using a ratio of peak areas or similar information of two chromatograms respectively obtained at the two wavelengths; b) a spectroscopic analyzer for spectroscopically analyzing a sample exiting from a component-separating column and for measuring an intensity at the second wavelength λ2 of the spectrum of the first component and an intensity at a wavelength λ3 of a spectrum of a second component at each point in time; and c) a concentration ratio calculator for calculating a ratio of concentration between the first component and the second component from: a chromatogram peak top height h1 and/or peak area A1 of the first component calculated from a peak height h2 and/or peak area A2 of a chromatogram peak corresponding to a spectrum peak of the first component at the second wavelength λ2 and the value R of the sensitivity coefficient; and a peak height h3 and/or peak area A3 of a chromatogram peak at the wavelength λ3.
