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 balancebetween voltammetric and potentiometric techniques. Emphasizing electroanalysis rather than physical electrochemistry, readers gain a deep understanding of the fundamentals of electrodereactions and electrochemical methods. Moreover, readers learn to apply their newfoundknowledge and skills to solve real-world analytical problems. The text consists of six expertly crafted chapters - Chapter 1 introduces fundamental aspects of electrode reactions and the structure of the interfacial region; Chapter 2 studies electrode reactions and high-resolution surface characterization, using techniques ranging from cyclic voltammetry to scanning probe microscopies; Chapter 3 features an overview of modern finite-current controlled potential techniques; Chapter 4 presents electrochemical instrumentation and electrode materials, including modified electrodes and ultramicroelectrodes; Chapter 5 details the principles of potentiometric measurements and various classes of ion selective electrodes; Chapter 6 explores the growing field of chemical sensors, including biosensors, gas sensors, microchip devices, and sensor arrays. 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.
