Zusammenfassung:	An automatic chemical analyzer has a compensation coefficient calculating section and a light-path-length-based compensating section. The calculating section obtains the ratio of the absorbancies measured of reaction cells filled with a sample of the known absorbancy to the absorbancy measured of each cell, thereby calculating compensation coefficients for the respective cells. The compensating section multiplies the absorbancies measured of the cells refilled with samples of different unknown absorbancies by the compensation coefficients calculated by the calculating section, thereby compensating the absorbancies for the light path lengths of the cells. The compensated absorbancies, i.e., the absorbancies of the samples, are used in analyzing the samples.
