Abstract

PURPOSE:To calculate the valve of an absorbance acculately without lowering the efficiency of analysis by measuring the quantity of incident light through all filters, by storing the photometric value previously, and by using data selected from a photometric value and the stored photometric value, for each sample. CONSTITUTION:In the stage for preparatory measurement, the quantity of incident light is measured through all filters and each measured value I0<i>(lambdai) is obtained and stored 17. In sample measurement, a reference reaction container containing a light-transmissive liquid and a reaction container 6 containing a sample are passed through the photometric position together and transmitted light passed through the reference reaction container and each of all filters is measured to store the obtained value IS(lambdai). With regard to reaction container 6, transmitted light passing through the filter that corresponds to an analysis item is photodetected at each photometric position of find measured value IX (lambdai), and then each stored value is read out. Then, absorbance value OD found from measured value IX (lambdai) at the (l)-th (l=1, 2-n) photometric position is passed through the filter having a wavelength (lambdai) without being passed through the reaction container to be calculated 16 by the equation I.
