Metal Wire Auxiliary Electrode - 35HX15 0.6/235 mm
The metal wire counter (auxiliary) electrode is provided in the 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 reaction conditions, typically platinum, rhodium, palladium, or gold wire. It well fits aqueous (FKM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.
This electrode is typically used with low volume (1-2 mL) electrochemical cells (e.g. spectro-electrochemical cells, or photo-electrochemical flow cells), where space limitations do not allow using 50HX15 0.6/250 mm model. 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 counter electrode for a certain amount of time. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass vial sealed with O-rings (all included in the package).
