In order to check a sample sucking condition at the sampling nozzle, minimum and maximum pressure values in normal sample sucking condition, and a judging value used in a formula for determining the sample sucking condition are preset. A pressure level before the start of the sample suction, a pressure level during the sample suction, and a pressure level immediately before the completion of the sample suction is measured. A clogged condition is detected during the sample suction. A normal condition and a no-sample condition are determined after the sample suction.
