Normal Polarography

The first important voltammetric technique to be developed—polarography—uses the dropping mercury electrode as the working electrode. As shown here, the current flowing through the electrochemical cell is measured while applying a linear potential ramp. Although polarography takes place in an … Continue reading

Shape of Voltammograms

In voltammetry we measure current as a function of the applied potential. The shape of a voltammogram is determined by several experimental factors, the most important of which are how we measure the current and whether convection is included as … Continue reading
