Before analysis, the correspondence between the vessel positions and the reaction vessels held in the vessel positions respectively at the time of completion of all the operations of a turntable upon completion of the last analysis are stored in a computer in advance. When a start switch is turned on, a judgment is made as to whether the correspondences between the vessel positions and the reaction vessels coincide with those stored in the computer or not. In the case of coincidence, reaction vessels in vessel positions are regarded as having been already cleaned, so that these reaction vessels are subjected to blank measurement and sample addition in the case of optical measurement, whereas these reaction vessels are directly subjected to sample addition in the case of ISE measurement.
