    摘要： An automatic analyser which is capable of detecting a dispensing abnormality with a high degree of accuracy without causing the decrease in the determination performance or the increase in the calculation amount caused by the configuration balance of the reference database is implemented. A dispensing nozzle of a sample dispensing mechanism 50 is immersed in a dispensing target contained in a specimen container 11 and sucks the dispensing target, and internal pressure of the dispensing nozzle of the sample dispensing mechanism 50 of ejecting the sucked dispensing target to a reaction container 41 is detected through a pressure sensor 54. A plurality of feature quantities are extracted from a waveform of the detected pressure, and a determination result is output through a linear combination formula using an optimal coefficient for a determination function that receives a plurality of feature quantities and outputs one value. The determination result indicates whether or not dispensing of the sample dispensing mechanism 50 is performed normally in accordance with the magnitude of the output result of the determination function.

    摘要： An object of the present invention is to provide a technology in which an amount of pigment carried from a pigment solution can be accurately measured at the time of testing a surface state of a dispensing probe on the basis of the amount of carried pigment. In a test method according to the present invention, a surface state of a dispensing probe is evaluated on the basis of an amount of pigment carried from an acidic pigment solution into a solution including no pigment (see FIG. 1 ).

    摘要： 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.
