Abstract: When washing the inside of a reactor vessel which is used repeatedly, a rough suction is performed before suctioning with a washing tip; however, unwanted washing liquid may remain that may affect analysis results. The present invention provides an automatic analysis device for analyzing a sample using light, in which the automatic analysis device is characterized in that: a washing mechanism comprises a washing liquid supply nozzle that supplies washing liquid to a reactor vessel after analysis, a washing liquid suction nozzle that suctions the supplied washing liquid, a washing tip provided to the bottom end of the washing liquid suction nozzle, and a rough suction nozzle that suctions, in advance, a liquid within the reactor vessel before suctioning with the washing tip; and after the rough suction, liquid is caused to remain so that the bottom surface of the reactor vessel is not exposed.

Abstract: The automatic analyzer includes: a liquid dispensing mechanism that performs suction of a liquid; a pressure sensor that measures a change of an internal pressure of a probe provided at the liquid dispensing mechanism; a determination section that determines whether the suction of the liquid by the probe is normal suction or air suction abnormality; an analysis section; a storage section that stores a cumulative number of times of air suction abnormality per liquid and an allowable cumulative number for the cumulative number of times of air suction abnormality; and a controller that exercises operation control over the liquid dispensing mechanism, the determination section, and the analysis section. The controller exercises control such that the cumulative number of times of air suction abnormality is updated and the updated cumulative number is stored in the storage section even if the air suction abnormality occurs non-consecutively.
