Abstract

The invention belongs to the technical field of analysis and detection, and relates to an electrochemiluminescence analyzing and detecting method. The scheme aims to solve the problems that as the electrode involved in the electrochemiluminescence analysis and detection is easily absorbed and polluted by organic impurities generated during electrolyzation, the reliability of the analysis and detection is affected. The method provided by the scheme comprises the following steps: erecting rod-shaped ultrasonic probe, placing a working end of the rod-shaped ultrasonic probe inside an electrolytic cell, installing and arranging an ultrasonic transduction device at the working end of the rod-shaped ultrasonic probe, connecting the rod-shaped ultrasonic probe with a high frequency oscillation electric signal generator, and energizing the high frequency oscillation electric signal generator. The method provided by the scheme can further include adjusting the ultrasonic frequency within the range of 80 KHz to 12 MHz. The method provided by the scheme can inhibit the absorption and pollution processes of an electrolysis product on the electrode by virtue of ultrasonic waves with extremely low power and very high frequency, and the damage impact of the ultrasonic cavitation effect of the ultrasonic waves can be overlooked.

Description

technical field [0001] The invention relates to an electrochemiluminescence analysis and detection method, which is an electrochemiluminescence analysis and detection method which is significantly improved on the basis of the usual electrochemiluminescence analysis and detection method, and belongs to the field of analysis and testing. Background technique [0002] The term electrochemiluminescence expresses its usual technical meaning is well known and will not be repeated here. [0003] The working electrode and the counter electrode, that is, the auxiliary electrode involved in electrochemiluminescence analysis and detection, are very susceptible to adsorption pollution of organic substances produced by electrolysis, especially when the glassy carbon electrode is used as the working electrode, the adsorption pollution is more serious , the adsorption pollution will lead to the rapid attenuation of the performance of the working electrode and the auxiliary electrode; there...
