[Task] To provide an automatic analysis apparatus including a photomultiplier tube which controls a sensitivity of the photomultiplier tube without adjusting a high voltage value. [Solution] An automatic analysis apparatus according to the present invention includes a photomultiplier tube which detects light from a reaction vessel; a determination unit which determines an output signal of the photomultiplier tube in a case where the photomultiplier tube is irradiated with first light; and a control unit which irradiates the photomultiplier tube with second light to lower a sensitivity of the photomultiplier tube in accordance with a determination result by the determination unit.

Automatic analysis apparatus and method for controlling automatic analysis apparatus

An automatic analyzer is equipped with a sterilization mechanism removably attached to an opening of a container that holds a reagent and having an ultraviolet light generation section that radiates ultraviolet light; a suction nozzle removably attached, together with the sterilization mechanism, to the opening of the container; an analysis section adding the reagent drawn in by suction from the container via the suction nozzle to the reagent, and executing an analysis operation; and a control section exercising variable control over an irradiation light intensity of the ultraviolet light generated by the ultraviolet light generation section.
