What the requirements for the auxiliary electrode?
The auxiliary electrode is typically a platinum wire that provides a surface for a redox reaction to balance the one occurring at the surface of the working electrode, and does not need special care, such as polishing. In order to support the current generated at the working electrode, the surface area of the auxiliary electrode must be equal to or larger than that of the working electrode. Three auxiliary electrodes are available from BAS: two are straight platinum wires for use with stationary solution voltammetry experiments, and the other (MW-1033) is a longer platinum coil that is used for experiments that generate larger currents, such as rotating disk voltammetry and bulk electrolysis. One of the platinum wire electrodes (MW-4130) should be used with C1 Cell Stands, the VC-2 Cell (MF-1052), the Microcell (MF-1065), and the C2 Low Volume Cell (MF-2040), whereas the other (MW-1032) should be used with the C2 and C3 Cell Stands.
