A typical arrangement for a voltammetric electrochemical cell is shown here. In addition to the working electrode, the reference electrode, and the auxiliary electrode, the cell also includes a N2-purge line for removing dissolved O2, and an optional stir bar. … Continue reading
Schematic diagram showing a solid electrode. The electrode is fashioned into a disk and sealed in the end of an inert polymer support along with an electrical lead.
Coulometry is based on an exhaustive electrolysis of the analyte. By exhaustive we mean that the analyte is completely oxidized or reduced at the working electrode or that it reacts completely with a reagent generated at the working electrode. During an … Continue reading
A potentiostat is used to set and control the potential of a working electrode. A schematic diagram for a manual potentiostat is shown here where W is the working electrode, A is the auxiliary electrode, R is the reference electrode, SW is … Continue reading
A galvanostat is used to control the current flowing through an electrochemical cell. A schematic diagram of a constant-current galvanostat is shown here where A is the auxiliary electrode, W is the working electrode, R is an optional reference electrode, E is a … Continue reading
