Pressure inside the dispensing nozzle of the dispensing mechanisms 50, 60, and 70 is detected, the dispensing mechanisms dipping a dispensing nozzle in a dispensing target contained in a container 11, 21, and 31, aspirating the dispensing target, and discharging the dispensing target to a reaction container 41; one item of the determination-purpose reference data is selected from the multiple items of the determination-purpose reference data which is stored in a storage unit 93 and used in determining whether or not the dispensing mechanisms 50, 60, and 70 are abnormal, based on the detection result from the pressure sensor 54 when the dispensing mechanisms 50, 60, and 70 dispense a reference dispensing target configured to contain a known ingredient; and whether or not the dispensing mechanisms 50, 60, and 70 are abnormal is determined, based on the detection result from the pressure sensor 54 and the selected determination-purpose reference data when the dispensing mechanisms 50, 60, and 70 dispense a dispensing target used in analysis. According to this, it is possible to reliably detect abnormal dispensing in a dispensing mechanism. |
