Estimating the term…
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.
An automatic analyzer which performs a suction operation a plurality of times on a same sample, the automatic analyzer comprising:
An automatic analyzer which performs a suction operation a plurality of times on the same sample, the automatic analyzer comprising:
A malfunction determination method for an automatic analyzer which performs a suction operation a plurality of times on the same sample, comprising:
A malfunction determination method for an automatic analyzer which performs a suction operation a plurality of times on the same sample, comprising comparing pressure change amounts at the two consecutive suction operations and determining the presence or absence of a failure in the first or second suction operation according to whether the difference between both pressure change amounts exceeds a threshold value set in advance.
