Abstract
In a method of analyzing chemical substances in sample liquids, reagent blank absorbances with respect to a light amount transmitted through air or water are measured previously at a plurality of photometering positions and are stored in a memory. Then sample absorbances are measured at respective photometering positions and the reagent blank absorbances are substrated from the sample absorbances at the respective photometering positions, so that a required absorbance variation of the sample liquid with respect to time is calculated from the sample absorbances thus corrected. Therefore, even if a calibration curve linearity is not perfectly identical with each other at the respective photometering positions, it is possible to obtain accurate analyzing results.
