How to polish the Working electrodes' surface with PK-3

  1. Prepare the glass plate, and put a few drops of polishing diamond on diamond polishing pad.
  2. Hold the CV electrode at right angle to the pad, and polish in a circular motion.
  3. 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.

Polishing of PFCE Electrode & Pyrolytic Graphite Electrode

PFCE electrode can regain its electrochemical sensitivity and reproducibility by polishing with Emery paper sic#4000. After the polishing, please clean its surface with ultrasonic cleaner for 10-60 seconds (@ frequency: 50 KHz, output power: 100 W). PFCE electrode is a significantly competent electrode. In order to keep its performance from going to be eroded, we recommend re-polishing after a certain period of time.

Use of distilled water is required during this procedure. Sic#2000 grade emery paper is used at the preliminary stage only for persistent stain.


Do not polish with a finer grade of emery paper ( #6000 etc.). PFCE electrode does not need mirror finishing like a GC electrode.
