PK-3 electrode polishing kit (Cat. No. 013223) is recommend for the regeneration of general working electrode surface.
The following is a guide on the different type of the working electrode polishing method using the PK-3 electrode polishing kit.
Polishing of General Working Electrode
In the case of general polishing, polish with alumina (step No. 3 and 4) are recommended. If regeneration of the electrode surface still does not work, try the diamond polishing first.
To ensure that alumina particles adhered to the electrode surface are removed, use a new alumina polishing pad, slightly polish the washed electrode, and then rinse the electrode surface with distilled water and dry.
- Prepare the glass plate, and put a few drops of polishing diamond on a wetted 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.
- Using a new alumina polishing pad, polish few times the electrode (for removing the alumina particles remaining on the electrode surface). Rinse the electrode surface with distilled water, and finish by air drying.
