Abstract: Provided is an automated analysis device capable of a more accurate determination of the sizes of bubbles included in a liquid. The automated analysis device includes a detection unit which detects bubbles included in a liquid, an internal standard solution syringe which executes a first liquid supply operation in which a liquid is supplied via the detection unit, a diluent syringe, a sipper syringe, solenoid valves, and a control device which determines whether the size of the bubbles detected during the first liquid supply operation is normal or not based on the operation speed of the liquid supply unit, and controls the operation of the liquid supply unit according to the determination.

Abstract: An automatic analysis device including liquid containers 3, 4, and 5 for storing liquid and liquid sending units 8, 9, and 10 for sending the liquid in the container through flow paths includes a detector 102 for detecting gas in the flow path, a priming function unit for replacing the liquid in the flow path, and a control device 29 for determining that bubbles are incorporated in the liquid in the flow path when the detector detects gas in the flow path. With this configuration, the incorporation of bubbles into a liquid and a shortage of a reagent can be more efficiently identified.
