Electroanalytical Methods

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.

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.

This text details contemporary electroanalytical strategies of biomolecules and electrical phenomena in biological systems.

A monograph on the theory of this procedure and its application to environmental monitoring. Considers all variants of stripping methods as a group of techniques used to study and analyze both solutions and solids. Reflects new qualitative standards attained by recently used electroanalytical stripping methods.

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.

This comprehensive presentation of the integral equation method as applied to electro-analytical experiments is suitable for electrochemists, mathematicians and industrial chemists. The discussion focuses on how integral equations can be derived for various kinds of electroanalytical models. The book begins with models independent of spatial coordinates, goes on to address models in one dimensional space geometry and ends with models dependent on two spatial coordinates. Bieniasz considers both semi-infinite and finite spatial domains as well as ways to deal with diffusion, convection, homogeneous reactions, adsorbed reactants and ohmic drops. Bieniasz also discusses mathematical characteristics of the integral equations in the wider context of integral equations known in mathematics. Part of the book is devoted to the solution methodology for the integral equations. As analytical solutions are rarely possible, attention is paid mostly to numerical methods and relevant software. This book includes examples taken from the literature and a thorough literature overview with emphasis on crucial aspects of the integral equation methodology.
