PURPOSE:To simply and efficiently wash a sampling tube by constituting this device so that a washing block in which the sampling tube is inserted through vertically is provided, and in the washing block, wash water is supplied and a sump solution is discharged. CONSTITUTION:In the figure, a sampling tube 1 descends and inserted into a sample container 17, and samples a sample liquid 18. After sampling is ended, the tube 1 is allowed to ascend by a fixed arm 2, and simultaneously, wash water 13 is supplied into the upper insert-through hole 7 from a supply port 10, while operating a vacuum pump 15. During this time, the liquid 18 adhering to the outside of the tube 1 is sucked from a discharge port 14, and subsequently, the outside of the tube 1 is washed the wash water 13 supplied to the insert- through hole 7. Next, when the lower end of the tube 1 reaches the ascending limit A, a sampling pump 3 operates. In such a way, the wash water 13 is sucked to the tube 1 and flows to a measuring cell 4, and the inside of the tube 1 and the cell 4 are washed. The wash water 13 used for washing is sucked from the discharge port 14. |
