重复的电化学氧化还原反应的实验,实验的产品上粘附到电极表面的电子转移速率,并逐渐衰减。如果电子转移速度变慢,对氧化还原峰电位差将拓宽之间。
清爽的电极表面通过抛光,电子转移速率将再次提高。因此,峰电位差变窄,返回到一个理想的简历。

-
Prepare the glass plate, and put a few drops of polishing diamond on diamond polishing pad.
-
Hold the CV electrode at right angle to the pad, and polish in a circular motion.
-
Replace the diamond pad to an alumina polishing pad, put a few drops of polishing alumina, and polish the electrode to be mirror surface. Rinse the electrode surface with distilled water, and finish by air drying.
Attention: Polishing with PK-3 is the most appropriate way to clean up electrode surface. Please consult us when other methods are applied.

It is recommended the follow polishing step:
-
Put a few drops of distilled water on the emery paper, and polish for 10 seconds. If necessary increase the polishing time.
-
Then rinse the electrode with distilled water.
-
After rinse, ultrasonic cleaning for 10 seconds (in the case of 65 W - 100 W ultrasonic cleaner).
Or polishing the electrode using alumina pad with a few drops of distilled water for about 10 seconds.
-
Then rinse the electrode again with a distilled water.
-
Dry the electrode and it is ready for the measurement.
For the PGBE electrode (Cat. No. 002252), because of the material characteristics, it is difficult to keep the perfect basal surface.
