Electrochemiluminescence three-electrode system without interference instant self-cleaning method

Abstract

The invention relates to an interference-free immediate self-cleaning method of an electrogenerated chemiluminescence three-electrode system, belonging to the field of analysis and test. How to realize immediate self-cleaning of a glassy carbon electrode on the premise of no additional interference is the problem which is unworthy of attention in the field. The interference-free immediate self-cleaning method mainly comprises the following steps of: a, placing one closed end of a pen cap-shaped or test tube-shaped ultrasonic energy absorber made of a micropore material inside an electrolyzer, and placing the working end of a reference electrode in an inner cavity of the ultrasonic energy absorber; and b, radiating ultrasonic waves to a solution inside the electrolyzer. According to the interference-free immediate self-cleaning method provided by the invention, the immediate self-cleaning is realized through radiating low-power and high-frequency ultrasonic waves; meanwhile, through the method for placing the ultrasonic energy absorber, the comprehensive interference of ultrasonic waves to the reference electrode is weakened, and the stable potential of the reference electrode is maintained.

Description

technical field [0001] The invention relates to an electrochemiluminescence three-electrode system instant self-cleaning method without interference, belonging to the field of analysis and testing. Background technique [0002] For professionals in the field of analytical chemistry, the technical meaning of the term electrochemiluminescence is well known and will not be repeated here. [0003] 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 cause the performance of the glassy carbon electrode to decay rapidly; therefore, how to perform the electrochemiluminescence detection operation At the same time, it has become a technical problem to be solved urgently to clean the glassy carbon electrode effectively and instantly without additional interference.
