This book has been written to become a bench book used in the laboratory. The "Electro analytical Methods" addresses chemists and biochemists that are interested in using electroanalytical techniques to supplement spectroscopic and perhaps theoretical calculations. It also addresses biologists, environmental and material scientists, physicists, medical scientists, and, most importantly, students in all branches of science, who are confronted with the need to apply electroanalytical techniques. In the short first part of the book, entitled "Basic Electrochemistry", the essentials of electrochemical thermodynamics and kinetics are given. The second part, entitled "Electro analytical Techniques", contains the most frequently utilized techniques, i.e., cyclic voltammetry, pulse and square-wave voltammetry, chronocoulometry, etc. The third part is devoted to electrodes and electrolytes, which are the major constituents of an electrochemical cell. Throughout the book, special attention is given to guide the user to successful laboratory experiments and a sound data evaluation.
