Abstract:
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 disk; a first detector disposed on a second base member that detects transmitted light from the mixture solution; one or more pairs of second detectors, that detect scattered light from the mixture solution, disposed on the second base member in a plane perpendicular to a direction of movement of the reaction disk, and the second detectors of each of the one or more pairs of second detectors are disposed symmetrically with respect to the first detector in the plane perpendicular to a direction of movement of the reaction disk and are each positioned at an angle having the same absolute value relative to the optical axis of irradiation of the light from the light source; and a controller programmed to compensate for thermal deformation of the first detector and the one or more pairs of second detectors by using one of an averaged value of light quantity data and a sum thereof from the first detector and the one or more pairs of second detectors to calculate a concentration of a measurement target substance in the mixture solution, wherein the first base member and the second base member are disposed on a third base member.
