The invention is simple to manufacture and convenient to use. The system is stable and is of low cost, which can facilitate in heating the working electrodes. The integrated thermal control ITO electrode electrochemiluminescence detection system has good sensitivity and repeatability on the detection of amines.

Description

technical field

[0001] The invention belongs to the field of electrochemical detection, and more specifically relates to a thermal control electrode electrochemiluminescence detection device and a preparation method for a detection cell. Background technique

[0002] Electrochemiluminescence (ECL) generally occurs on or near the electrode surface. Usually, people can change the strength and characteristics of ECL by adjusting the relative position of the electrodes, changing the potential applied to the electrodes and changing the electrode materials to obtain the best results. test results. At present, all studies on ECL are carried out at room temperature, but in fact, the ECL that occurs on the electrode surface is not only related to the diffusion of luminescent substances on the electrode surface, but also closely related to kinetic factors such as the mass transfer rate of luminescent substances. The temperature of the surface has a significant influence on these fact...
