Abstract

PURPOSE:To prevent air from remaining in a conduit which may cause buffering action by forming the stator-side sample setting conduit of a sample metering-collecting valve by using a couple of conduits crossing on the top surface, and by flushing it together with a sample set pump. CONSTITUTION:Through sample set pump 14, sample 19 is sucked from conduit 5 of rotor 3 of sample metering-collecting valve 1 to pipe 5 to the degree that it exceeds slightly the top ends of conduits 30 and 31 crossing at the top surface of stator 2. Then, a constant quantity of the sample is dispensed to sample collecting conduits 7a, 8a... successively via sampling pump 17a by connections of pipe 5 to sample collecting openings 6a... through the rotation of rotor 3, synchronous change- over of channel selector valve 10, etc. On the completion of this sampling, change- over valves 21 and 22 are changed over and flushing pump 26 is actuated. As a result, flushing water in flushing water tank 32 is discharged via valve 21, pump 14, pipes 30 and 31, and valve 22, and pipes 30 and 31 are filled with the flusing water to prevent the remaining of air which may cause buffering action, so that the following sampling can be performed with accuracy.
