Abstract

The invention discloses an online electrochemical measuring device, belonging to the technical field of electrochemical analysis and quantitative analysis. The online electrochemical measuring device comprises a microcomputer control system and an electrolytic cell system, a microcomputer control peristaltic pump and an electromagnetic valve are used for taking a sample and a blending agent according to a certain proportion and putting the sample and the blending agent into a liquid-phase reagent cup, a micro-sample injection pump is used for conveying a liquid phase to an electrolytic cell constituted by a three-electrode system and an electrolyte at a certain speed, three electrodes in the electrolytic cell are connected with an electrochemical workstation, after the liquid conveying of the micro-sample injection pump is finished, the electrochemical workstation is automatically triggered to enter into a detection procedure, and after the detection procedure is completed, the device is used for judging whether liquid drainage and cleaning are required or not and waiting for the coming of next measurement time. The device has the advantages of simple structure and good stability, and can be operated manually or automatically and be widely applied to measuring systems of the electrochemical workstations.

Description

technical field [0001] The invention relates to an online electrochemical measuring device. The invention belongs to the technical field of electrochemical analysis and quantitative analysis. Background technique [0002] The on-line electrochemical measurement device is a fully automatic on-line device that can regularly and quantitatively pipette the measured sample, send it into the electrolytic cell at a certain speed, and then trigger the electrochemical workstation to perform electrolytic measurement. It is used to realize the electrochemical workstation. Automatic quantitative addition of various test solutions in online measurement or analytical testing. In conventional electrochemical analysis, pipetting samples or replacing solutions is usually a manual operation, which is time-consuming and labor-intensive. Due to human factors, measurement errors may occur. The measured samples need to be collected in the laboratory for analysis, and cannot be reported for analy...
