Abstract
A liquid chromatograph control apparatus for controlling the solvent mixing ratios of liquid chromatography, comprising a storage means for storing the correspondence relationship between the plural discrete Rf values obtained by thin layer chromatography performed on respective samples at a preset solvent mixing ratio and the appropriate sequences of solvent mixing ratios of liquid chromatography for the respective samples; an arithmetic means for obtaining, by interpolation, the appropriate sequence of solvent mixing ratios corresponding to any Rf value falling between the stored Rf values adjacent to each other; and an image processing means for imaging the thin layer plates obtained by performing thin layer chromatography, to obtain Rf values from the images.
