PROBLEM TO BE SOLVED: To provide a system for increasing an air suction detection ratio in a dispensing probe for sucking a sample or reagent and preventing waste of the sample and reagent for remeasurement by incorrect determination, in an automatic analyzer. SOLUTION: As the method of creating a threshold for determining air suction, an algorithm is applied for performing suction rate correction by a plurality of air suction operations of different amount in advance, sensor drift correction by comparing the pressure sensor output at the non-suction time just before the suction in the suction operation with the pressure sensor output at the non-suction time obtained at an arbitrary time, and the correction of the effect of liquid type and dispersing probe height by comparing the pressure sensor output just before starting the suction after a liquid detection state with the pressure sensor output during the suction operation and just after the completion of the suction operation.
