Abstract

The invention discloses a measuring and cleaning device suitable for microelement detection and belongs to polarographic chemical analysis and measuring equipment. The measuring and cleaning device suitable for the microelement detection comprises a polarogram measuring disc containing measuring cups, a polarogram electrode and a reagent adding device, wherein the polarogram electrode and the reagent adding device are arranged above the polarogram measuring disc. The measuring and cleaning device suitable for the microelement detection is characterized in that a measuring cup A, a measuring cup B and a measuring cup C are tightly arranged on the same arc which takes a center of the polarogram measuring disc as a center, bottoms of the measuring cups respectively pass through an electromagnetic valve A, an electromagnetic valve B and an electromagnetic valve C to be connected with a sealed communication machine through a guide pipe, a pipeline of the bottom of the communication machine passes through an electromagnetic valve of a waste liquid barrel and is connected with the waste liquid barrel, a plunger vacuum pump is connected with the communication machine, and a stepping motor is arranged below the polarogram measuring disc. The measuring and cleaning device achieves the aim that reagent waste liquid and cleaning waste liquid are collected into the waste liquid barrel under a full-sealing state, and overcomes the defects that in the prior art, mercury volatilizing is easily caused by waste liquid to cause polluting, and cleaning is not easily controlled.

Description

technical field [0001] The invention belongs to polarographic chemical analysis and measurement equipment, in particular to a measurement and cleaning device suitable for trace element detection. Background technique [0002] In the method of polarographic analysis to measure trace elements, it is necessary to continuously generate new mercury droplets to participate in the measurement process. Due to the special physical and chemical properties of mercury, it is necessary to collect the waste mercury generated during the measurement process in a complete and timely manner to reduce mercury residues and Volatility, Chinese patent 201010285184.2 discloses an automatic sampling mechanism for an analytical instrument. There is a frame on which a stepping motor, a pipette driving device and a liquid collection box are installed, and a detection cup transmission device is installed in the liquid collection box , several detection cups are installed on the detection cup transmissi...
