PURPOSE:To facilitate the accuracy management of a measurement data and the operation of an analysis/measurement section, by discriminating the conditions corresponding to the suction or discharge state of a suction/discharge nozzle in a sampling section. CONSTITUTION:A sampling section 2 includes a suction/discharge nozzle 10 adapted to suck a sample stored in a sample cup 8 and discharge it to reaction tubes at an analysis/measurement 1, a syringe 13 for supply the pressure of sucking or discharging the sample and a pressure sensor 3 to which the suction or the discharge/pressure of the nozzle 10 is transmitted and for example, a suction pressure value in the nozzle 10 as detected with the sensor 3 is sent out to an A/D converter 4. On the other hand, a control section 5 containing a CPU judges which the digital value from a converter 4 belong to among preset five identification stages, and sends out a measurement signal or non- measurement signal to the analysis/measurement section 1 according to the results, besides controlling a nozzle driving section. Then, an error display 6 is done on the basis of the signal from the control section 5 to give an alarm 7. |
