The scope of this book is to guide students and scientists to successful experiments and applications of modern electroanalytical techniques. It is written for chemists, biochemists, biologists, environmental and material scientists, physicists, medical scientists, and, most importantly, students of all branches of science. The book does not require any specialization in electrochemistry. A basic knowledge of chemistry and physics is sufficient. Electroanalytical techniques give access to a variety of most important information on chemical, biochemical and physical systems. This book provides the necessary theoretical background of electrochemistry and the most frequently used measuring techniques. Special attention is given to experimental details and data evaluation.
