Abstract
A system for processing chromatographic data which comprises an input for data representative of two chromatograms x and y, a memory for storing the inputted data of the chromatograms, and a computer operative to read out, from the memory, retention times x.sub.i and y.sub.i (i=1, . . . , n; n.gtoreq.2) of at least two principal peaks of the chromatograms, respectively, and derive one function for converting the retention times x.sub.i to y.sub.i using the chromatogram y as the reference chromatogram, which gives a minimum estimated error. The computer is further operative to calculate, on the basis of the derived function, the modified retention time x'.sub.j of all the peaks of the chromatogram x. Therefore, the system permits to eliminate errors orginated from the judgment of a skilled person and to indentify and quantitatively analyze chromatogram obtained precisely without skill.
