Embodiment 1
[0017] Embodiment 1, a kind of measuring and cleaning device that is suitable for trace element detection, comprises the polarographic measuring plate 2 that measuring cup is housed and is positioned at the polarographic electrode 6 above the polarographic measuring plate, reagent adding device, it is characterized in that: measure Cup A1, measuring cup B9, and measuring cup C10 are closely arranged on the same circular arc with the center of the polarographic measuring disc as the center. The valve C13 is connected with the sealed connector 14, the pipeline at the bottom of the connector is connected to the waste liquid bucket 8 through the waste liquid bucket solenoid valve 7, the plunger vacuum pump 5 is connected to the connector, and a step is installed under the polarographic measuring plate. Enter motor 3.
[0018] The flexible catheter is a silicone catheter. The solenoid valve is a pinch valve.
