Abstract
A data processing system including a sensitivity coefficient holder for holding a value R of a sensitivity coefficient for a wavelength λbelonging to one peak in a spectrum of a first component and a second wavelength λbelonging to the same peak and having a lower intensity than λ, 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 λof the spectrum of the first component and an intensity at a wavelength λof 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.
