PURPOSE:To enhance the capacity of analytical treatment, forming a V-shaped upper open surface to a washing tank so as to make the trough part thereof oppose to the leading end of a revolvably driven sampling nozzle. CONSTITUTION:A washing tank 4 is provided with a water flowing nozzle 8 connected to a washing water injecting tube 10 and a V-shaped upper open surface is formed to said tank 4 so as to make the trough part thereof oppose to the leading end of a rotatably driven sampling nozzle 2 and to enable the passage of the sampling along the valley part of the upper open surface. In this case, the emission of washing water is stopped after the passage of the sampling nozzle 2 and washing water flooded from the washing tank 4 is fallen into a washing water receiver 7 to be discharged. By this constitution, the capacity of analytical treatment can be remarkably enhanced without affecting influence to analytical preciseness. |
