摘要： PURPOSE:To maintain electrolyte in a measuring cell at a constant quantity all the time, by automatically injecting sample liquid in the measuring cell, and automatically discharging the electrolyte corresponding to the quantity of the injected sample liquid out of the measuring cell at the same time to the outside of this system. CONSTITUTION:A through holes 17' at one side of rotated disc 20 is filed with sample liquid. The sample liquid is dilluted with electrolyte 1, which is circulated in a liquid sending path 5 by a circulating pump 22, and injected into a measuring cell 2 through the liquid sending path 5. At the same time, the electrolyte 1, which is put in another through hole 17 of the rotated disc 20, is discharged to the outside of this system through a liquid discharge path 6 naturally or by a liquid discharging pump. The through holes 17 and 17' of the rotated disc 20 have the same volume. The electrolyte 1 which has the quantity corresponding to the quantity of the sample 3 injected in the cell 3 is discharged to the outside of this system. Therefore, the quantity of the electrolyte 1 in the cell 3 can be kept at the constant quantity all the time even if continuous measurement is repeated.

摘要： 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.
