Abstract
An automatic analyzer has a multi-wavelength light source that irradiates a reaction cuvette containing a liquid mixture of a sample to be analyzed and a reagent. A transmitted-light quantity detector detects the amount of light transmitted through the reaction cuvette and internal contents of the reaction cuvette. A single-wavelength light source irradiates the reaction cuvette with single-wavelength light; and a transmitted-light quantity detector detects the amount of single-wavelength light scattered from the reaction cuvette. A memory stores the results of the transmitted-light quantity detection and the scattered-light quantity detection; and the deterioration states of the single-wavelength light source, multi-wavelength light source, and reaction cuvette are determined in accordance with measurement results of cell blank measurements conducted on the reaction cuvette where a predetermined reference solution is stored to detect the amount of light transmitted through and the amount of light scattered from.
