Metal Wire Auxiliary Electrode

The metal wire counter (auxiliary) electrode is provided in electrochemical cell as a current sink to shunt excess current away from the reference electrode. The counter electrode is generally chosen to be inert under the reaction conditions, typically platinum, rhodium, palladium or gold wire. The plug is made of PEEK. It well fits aqueous (EPDM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.

The metal wire electrode is immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the wire electrode for a certain amount of time. After the process, the electrode should be washed several times with ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass tube sealed with O-rings (all included in the package).
