This laboratory book delivers hands-on advice to researchers in all fields of life and physical sciences already applying or intending to apply electro-analytical methods in their research. The authors represent in a strictly practice-oriented manner not only the necessary theoretical background but also substantial know-how on measurement techniques, interpretation of data, experimental setup and trouble shooting. The author and the editor are well-known specialists in their field.

Researchers and professionals will find a hands-on guide to successful experiments and applications of modern electroanalytical techniques here. The new edition has been completely revised and extended by a chapter on quartz-crystal microbalances. The book is written for chemists, biochemists, environmental and materials scientists, and physicists. A basic knowledge of chemistry and physics is sufficient for understanding the described methods. Electroanalytical techniques are particularly useful for qualitative and quantitative analysis of chemical, biochemical, and physical systems. Experienced experts provide the necessary theoretical background of electrochemistry and thoroughly describe frequently used measuring techniques. Special attention is given to experimental details and data evaluation.

Das führende Werk auf seinem Gebiet - jetzt durchgängig auf den neuesten Stand gebracht! Die theoretischen Grundlagen der Elektrochemie, erweitert um die aktuellsten Erkenntnisse in der Theorie des Elektronentransfers, werden hier ebenso besprochen wie alle wichtigen Anwendungen, darunter modernste Verfahren (Ultramikroelektroden, modifizierte Elektroden, LCEC, Impedanzspektrometrie, neue Varianten der Pulsvoltammetrie und andere). In erster Linie als Lehrbuch gedacht, läßt sich das Werk aber auch hervorragend zum Selbststudium und zur Auffrischung des Wissensstandes verwenden. Lediglich elementare Grundkenntnisse der physikalischen Chemie werden vorausgesetzt.

The critically acclaimed guide to the principles, techniques, and instruments of electroanalytical chemistry-now expanded and revised Joseph Wang, internationally renowned authority on electroanalytical techniques, thoroughly revises his acclaimed book to reflect the rapid growth the field has experienced in recent years. He substantially expands the theoretical discussion while providing comprehensive coverage of the latest advances through late 1999, introducing such exciting new topics as self-assembled monolayers, DNA biosensors, lab-on-a-chip, detection for capillary electrophoresis, single molecule detection, and sol-gel surface modification. Along with numerous references from the current literature and new worked-out examples, Analytical Electrochemistry, Second Edition offers clear, reader-friendly explanations of the fundamental principles of electrochemical processes as well as important insight into the potential of electroanalysis for problem solving in a wide range of fields, from clinical diagnostics to environmental science. Key topics include: The basics of electrode reactions and the structure of the interfacial region Tools for elucidating electrode reactions and high-resolution surface characterization An overview of finite-current controlled potential techniques Electrochemical instrumentation and electrode materials Principles of potentiometric measurements and ion-selective electrodes Chemical sensors, including biosensors, gas sensors, solid-state devices, and sensor arrays

Electrochemistry plays an important role in preserving our cultural heritage. For the first time this has been documented in the present volume. Coverage includes both electrochemical processes such as corrosion and electroanalytical techniques allowing to analyse micro- and nanosamples from works of art or archaeological finds. While this volume is primarily aimed at electrochemists and analytical chemists, it also contains relevant information for conservators, restorers, and archaeologists.

This text details contemporary electroanalytical strategies of biomolecules and electrical phenomena in biological systems. It presents developments in sequence-specific DNA detection for more efficient medical diagnosis of genetic and infectious diseases and microbial and viral pathogens.
