Electrochemistry involves a fairly wide range of electrical techniques that can be used for analytical purposes including potentiometry, pH measurement, ion selective techniques, voltammetry, cyclic voltammetry, polarography, electrochemical stripping, electrical conductance, biosensor technology and the separation techniques, electrophoresis, capillary electrophoresis and isotachophoresis. Electrochemical techniques are relatively simple with generally straightforward types of apparatus (often quite compact), easy to use, and most of them will provide fairly rapid results. This book is written for the analyst to explain the function of many of these techniques and aid in the selection and their use for analytical purposes. It will describe the basic principals involved in each technique, the basic equipment required and how to use it. However, the book is basic and is not written for the specialist electrochemist carrying out advanced research and development of the techniques.
