Polarographic and voltammetric analysis methods have been an important aid for many years, particularly for trace analysis in the chemical analysis sector. This importance is based on their high accuracy and sensitivity, the possibility of carrying out multi-element analyses and the favorable price-performance ratio.

The mercury electrode is to be regarded as being one of the most efficient electrodes used in electroanalysis. For its use in solving electroanalytical problems the 757 VA Computrace offers a wide range of different techniques. These range from the classical direct current polarography – voltammetry at the dropping mercury electrode – up to the most modern stripping analysis method at a hanging mercury drop.

The following experiments are intended to provide an introduction to the basic principles of polarography and voltammetry at the mercury electrode and provide examples showing the use of these methods in analytical chemistry.
