Abstract

The invention relates to an electrochemiluminescence analysis device with a plurality of additional functions and belongs to the field of analysis and test. A glassy carbon electrode in electrochemiluminescence is easily subjected to absorption pollution. The invention aims to solve a package to relevant problems on the premise of not introducing additional interference. The device provided by the invention structurally comprises an electrolytic cell, a glassy carbon electrode, a counter electrode and a reference electrode, wherein the glassy carbon electrode, the counter electrode and the reference electrode are inserted in the electrolytic cell. Importantly, the device further structurally comprises a rod-like ultrasonic probe; the working end of the rod-like ultrasonic probe is inserted into the inside of the electrolytic cell; the outline of the rod-like ultrasonic probe is an ultrasonic energy absorber made of a micro-pore material in a pen sleeve shape or a test tube shape; and the working end of the reference electrode is inserted into the inner cavity of the ultrasonic energy absorber. By utilizing the device provided by the invention, the glassy carbon electrode can be ultrasonically cleaned. Furthermore, the comprehensive interference of ultrasonic waves on the reference electrode is restrained through the ultrasonic energy absorber. The device provided by the invention further has an electric-sound double-motivation activated chemical luminescence analysis and detection function.

Description

technical field [0001] The invention relates to an electrochemiluminescence analysis device with multiple additional functions, which belongs to the field of analysis and testing. Background technique [0002] The glassy carbon electrode in the device involved in the electrochemiluminescence detection is very susceptible to the adsorption pollution of organic substances produced by electrolysis, and the adsorption pollution will lead to the rapid attenuation of the performance of the glassy carbon electrode; therefore, how to perform electrochemiluminescence detection While operating, it becomes an urgent technical problem to clean the glassy carbon electrode effectively, instantly and without additional interference.
