ABSTRACT:
An automatic analyzer of a single-line and multi-item type having a circular reaction line along which a number of reaction vessels are transported in the stepwise manner, and a photometering apparatus in which white light is divided into a plurality of light beams having different wavelengths, by means of a diffraction grating, and the light beams are transmitted by means of light guides whose exit ends are arranged along the reaction line with a pitch which is different from that with which the reaction vessels are arranged. While the reaction vessels are moved by one pitch, a plurality of reaction vessels are photometered in time sequential manner.
