The detection pool has features of high integration degree, compactness, simple manufacture technique, low cost and repeated use.

Description

technical field [0001] The invention relates to a heating type electrochemical micro detection cell integrated on conductive glass. technical background [0002] The electrochemical detection cell is a device used to detect and study the electrochemical activity of substances. It is generally composed of a three-electrode system composed of a working electrode, an auxiliary electrode and a reference electrode, and an appropriate amount of electrolyte solution. The three-electrode system of the traditional electrochemiluminescence detection cell has a large size and poor integration, and the volume of the electrolyte solution required is large, which not only wastes analytical reagents, increases the cost of the experiment, but also increases the environmental pollution of the waste liquid after the experiment.

Problems solved by technology

The three-electrode system of the traditional electrochemiluminescence detection cell has a large size and poor integration, and the volume of the required electrolyte solution is large, which not only wastes analytical reagents, increases the cost of the experiment, but also increases the environmental pollution of the waste liquid after the experiment.

At present, electrochemical researchers at home and abroad have made various attempts to integrate the three-electrode system, mainly to develop printed electrodes based on carbon and gold materials, and to a certain extent have realized the integration of the three-electrode system, but so far the printed electrode The production process is relatively complicated and the reproducibility is poor. The production process uses precious metals such as silver and gold, and the cost is relatively high, which limits the promotion of printed electrodes.

In addition, printed electrodes are basically made of disposable type, that is, they are discarded after the experiment is completed. However, since the matrix materials of printed electrodes are mostly plastics that are difficult to decompose, a large amount of discarding will inevitably cause severe environmental problems.
