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 […]
In a potentiometric electrochemical cell one half-cell provides a known reference potential and the potential of the other half-cell indicates the analyte’s concentration. The ideal reference electrode provides a stable, known potential so […]
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 […]
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 […]
