Abstract
Official abstract text for this publication.
The scattered light from the measurement target substance passes through a light receiving window, and is received by a detector for +θ scattered light and a detector for −θ scattered light which are arranged symmetrically to each other across an optical axis at an equal angle or an equal interval in a vertical direction. A light source is fixed by a light-source holder (that is a base member on which the light source is arranged), and the detectors are arranged on and fixed to a detector holder (that is a base member on which the detectors are arranged). In this manner, drift of the light quantity data caused by the thermal deformation of the optical system can be corrected by comparing values of the light quantity data of the detectors.
First claim
Opening claim text (preview).
The invention claimed is: 1. An automatic analyzer comprising: a reaction disk that retains a plurality of reaction containers disposed circumferentially around the reaction disk and that repeatedly rotates and stops; a light source disposed on a first base member that irradiates a reaction container with light, the reaction container being arranged at a photometric position and housing a mixture solution of a reagent and a sample retained in reaction container on the reaction d…
