Voltammetric techniques of analysis - those based on the measurement of current resulting from an oxidation or reduction at an electrochemical cell - have assumed an important place in the arsenal of analytical tools for the identification and determination of trace concentrations of many organic, organometallic and inorganic molecules of biological significance. This critical discussion of recent applications of voltammetry is subdivided according to the nature of the electroactive functional groups present in the overall molecular structures, and listed under nitrogen-, sulphur-, oxygen-containing molecules, hydrocarbons, halogen containing and organophosphorus molecules, organometallics and selected inorganic molecules. Wherever possible, a critical comparison is made between these voltammetric methods and competing analytical methods based primarily on chromatographic and spectroscopic techniques.
