ABSTRACT:
A data processor for chromatography operates to separately recognize the peaks of a composite peak of a chromatogram. At first, in order to separate the peaks, the maximum point of the peak of the chromatogram is determined, and extrapolation lines are drawn from said maximum point to the individual points of the chromatogram, and then the gradients of the lines changing from the minimum to the maximum are determined. By determining the changes of the gradients of the extrapolation lines and intersection points of the extrapolation lines and the chromatogram, the major and minor peak are separated so that the shoulder peak can be judged remarkably accurately.
