摘要： An automatic analyzer which performs a suction operation a plurality of times on a same sample has a sample dispensing unit 9, a liquid level sensor which detects the liquid level of the sample in a sample vessel 8, an arithmetic unit 5 which computes a liquid level height h1 at the end of a first suction operation of the two consecutive suction operations from a liquid level height h0 and a sample suction volume V1 detected at the start of the first suction operation, a storage unit 7 which stores the liquid level height h1 computed by the arithmetic unit 5, and a determination unit 18 which compares a liquid level height h2 detected at the start of a second suction operation following the first suction operation with the liquid level height h1 at the end of the first suction operation.

摘要： A plunger is moved downwardly in predetermined distance while the tip of the sample probe is immersed in a sample to suck the sample into the probe. A pressure sensor detects the pressure fluctuation during the suction operation, an AD converter converting the signals into digital signals to send the signals for a signal processing unit. The signal processing unit extracts feature variables data of a suction waveform to calculate the Statistical distance from normal group data. The Statistical distance an a threshold value are compared with each other, it is judged that there is an abnormality in the suction operation when the Statistical distance is more than or equal to the threshold value. When the Statistical distance is smaller than the threshold value, an operation is proceeded to a discharge operation.

摘要： A plunger 66 is moved downwardly in predetermined distance while the tip of the sample probe 15 is immersed in a sample to suck the sample into the probe. A pressure sensor 26 detects the pressure fluctuation during the suction operation, an AD converter converting the signals into digital signals to send the signals for a signal processing unit 76. The signal processing unit 76 extracts feature variables data of a suction waveform to calculate the Statistical distance D from normal group data. The Statistical distance D an a threshold value th are compared with each other, it is judged that there is an abnormality in the suction operation when the Statistical distance D is more than or equal to the threshold value th. When the Statistical distance D is smaller than the threshold value th, an operation is proceeded to a discharge operation.
