Abstract: 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.

Abstract: An automatic analysis apparatus comprises: a light source generating light having a center wavelength equal to or shorter than 340 nm; a fluorescent substance excited by the light source light, and generates light together with transmitted light from the light source, having a wavelength of 340 nm to 800 nm; a condenser lens; at least one slit; a reaction cell holding a reaction solution where a specimen and reagent are mixed, and that the light source light and the light from the fluorescent substance enter; and a detector that detects light transmitted through the reaction cell. The light source, fluorescent substance, condenser lens, and slit are provided along a straight light corresponding to the optical axis. The width of the slit's opening is equal to or narrower than the width of a ray forming an image of the light source at the position of the slit.
