AUTOANALYZER AND SAMPLE DISPENSING METHOD

PROBLEM TO BE SOLVED: To properly wash a sample dispensing probe by avoiding the problem brought about by excessive immersion of the sample dispensing probe. SOLUTION: The detected difference between liquid surface height and suction height H3 is calculated by a control part (control means), and when this difference is larger than an upper limit value, a sample is determined as being excessive, and the dispensation of the sample is stopped. When the value of the calculated difference is an immersion upper limit value or below and an immersion lower limit value or above, the amount of the sample is determined as being proper, and the sample dispensing probe is allowed to fall to the preset suction height H3, to perform the suction operation of a blood corpuscle component. The sample-dispensing probe is washed, in a portion that corresponds from the immersion upper limit value to the immersion lower limit value. COPYRIGHT: (C)2011,JPO&INPIT
