Abstract

PURPOSE:To permit a liquid chromatograph to automatically analyze a living body fluid by adding to it memories and the like for storing two kinds of data: the hold time and the ratio of the detection signals at specific two wavelengths. CONSTITUTION:Successively connected to a photometer 8 are memories 10a and 10b, display 11, data processor 12, retriever 13, disk memory 14 and printer 15, which are controlled by a microcomputer 18 having a control interface 16, magnetic card 17 and input key panel 19. Thus, the outputs from a plurality of photoactive elements are stored in the memory 10a at specific time intervals, before being processed in the data processor 12 to obtain the hold time of the eluted constituent and the absorbance at each wavelength during the time as well as compute each ratio of the absorbances at two wavelengths, and each pair of the value and the hold time is stored in the memory 10b. The content is taken out for the retriever 13 to retrieve the forecast data on the analytical object filed in the disk memory 14, and the content is printed on the printer 15.
