The purpose of the polish is to remove redox reaction products accumulated on the working electrode surface. The polishing maintains a good condition of working electrode for CV/Flow cell.

|
With repeated electrochemical redox reaction experiments, the adhesion of the experimental products on to the electrode surface, and the electron transfer rate is attenuated gradually. If the electron transfer speed becomes slow, the difference between peak potentials for oxidation and reduction will broaden. |
 |
Refreshing the electrode surface by polishing, the electron transfer rate will increase again. Consequently, the peak potential difference becomes narrow and returns to an ideal CV. Electrode: Glassy carbon electrode |

It is recommended the follow polishing step:
∗For the PGBE electrode (Cat. No. 002252), because of the material characteristics, it is difficult to keep the perfect basal surface. For the precise PGBE basal surface treatment evaluation, you can have the publications below as a reference.
Here is a movie to show you how to polish electrode with our alumina polishing kit (PK-3).
Please, don't use poor quality alumina, as it is not enough efficient for polishing.
