The working electrode is the electrode in an electrochemical system on which the reaction of interest is occurring. The working electrode is often used in conjunction with an auxiliary electrode, and a reference electrode in a three electrode system. Depending on whether the reaction on the electrode is a reduction or an oxidation, the working electrode can be referred to as either cathodic or anodic. Common working electrodes can consist of inert metals such as gold, silver or platinum, to inert carbon such as glassy carbon or pyrolytic carbon, and mercury drop and film electrodes. Chemically modified electrodes are employed for the analysis of both organic molecules as well as metal ions.

Famous quotes containing the word working:
“The generation of women before us who rushed to fill the corporate ranks altered our expectations of what working motherhood could be, tempered our ambition, and exploded the supermom myth many of us held dear.”
—Melinda M. Marshall (20th century)
