Overview

The greatly expanded Third Edition of this internationally respected text continues to provide readers with a complete panorama of electroanalytical techniques and devices, offering a balance between voltammetric and potentiometric techniques. Emphasizing electroanalysis rather than physical electrochemistry, readers gain a deep understanding of the fundamentals of electrode reactions and electrochemical methods. Moreover, readers learn to apply their newfound knowledge and skills to solve real-world analytical problems.

Among the new topics covered, readers discover DNA biosensors, impedance spectroscopy, detection of capillary electrophoresis, diamond electrodes, carbon-nanotube and nanoparticle-based arrays and devices, large-amplitude AC voltammetry, solid-state ion-selective electrodes, ion selective electrodes for trace analysis, and lab-on-a-chip devices. New figures, worked examples, and end-of-chapter questions have also been added to this edition.

Given the rapid pace of discovery and growth of new applications in the field, this text is essential for an up-to-date presentation of the latest advances in methodologies, sensors, detectors, and microchips. It is recommended for graduate-level courses in electroanalytical chemistry and as a supplement for upper-level undergraduate courses in instrumental analysis. The text also meets the reference needs for any industry, government, or academic laboratory engaged in electroanalysis and biosensors.
