Using a molecular approach, it offers a concise and critical discussion of the latest applications of voltammetry to identify and determine biologically significant molecules such as drugs, pollutants, neurotransmitters, food additives and contaminants. Includes techniques on square wave and stripping voltammetry, differential pulse polarography, ion and high performance liquid chromatography, electrochemical detection coupled with flow injection analysis, electrochemical immunoassay and amperometric biosensors.
Trace Analysis is a highly practical book which deals with the science rather than the paperwork of quality assurance systems. Produced as part of the UK Valid Analytical Measurement (VAM) initiative, it provides the analyst with a systematic approach across the broad spectrum of trace analysis, offering practical advice and guidance on methodology and techniques. The book is structured to take the analyst step-by-step through the stages of any trace analysis. The approach is general, being broken down only into types of analyte. Additional chapters explain the application of groups of techniques to each analyte type. Each section contains references to published material which will allow the analyst to obtain further information on specific topics. Throughout the book, the analyst is reminded of pitfalls which lead to unreliable results. This new book therefore offers invaluable advice to analysts in all areas and at all levels, providing practical 'expert' advice on methodology. It will prove indispensable as a single, comprehensive bench guide for analysts in university, college and industrial laboratories.
Electrochemistry is a well established discipline that has encompassed both applied and fundamental aspects of chemistry courses for nearly a century. In recent years, however, it has become obvious that even broader applications of this valuable technique are now available to advance knowledge and solve problems in organic, inorganic and biological chemistry. In this book, it is shown how a range of limitations that historically have restricted the use of voltammetric and related electrochemical techniques have been removed or minimised so that it is now possible to work in the gas and solid phases as well as the traditional liquid phase. Significant advances in theory, instrumentation and electrode design have also made the technique more user-friendly. The initial chapters of this book describe the basic theory and philosophy behind the modern, widespread use of voltammetric techniques. The later chapters provide examples of new areas of application and predict future possibilities for this exciting area.
This introduction to the principles and application of electrochemistry is presented in a manner designed for undergraduates in chemistry and related fields. The author covers the essential aspects of the subject and points the way to further study, his concern being with the overall shape of electrochemistry, its coherence and its wider application. This edition differs from its predecessors in having principles and applications separated, and greater prominence is given to areas such as electrochemical sensors and electroanalytical techniques, of which a number of modern methods were not included in previous editions. A range of numerical problems and outline solutions is provided for each chapter to cover most situations that a student might encounter.
...this is a valuable addition to the food analyst;s library. It brings together a well balanced account of the methods available an the literature cited will provide the analyst with all the details needed for setting up water-soluble vitamin assays and further reading to understand why these vitamins are important to those concerned with human nutrition. ' - International Journal of Food Science and Technology This book is of practical use as a tool and reference work of laboratory managers, senior analysts and laboratory technicians in food and vitamin manufactrurinf companies, for those in govenment and research institutes and for medical researchers, public analyst and nutritionist, It can also be recommended for a broad audience including lectures, students of natural sciences and food technologist. - lesbensm Wiss und Technol.'I recommend Water-soluble vitamins Assays in Human Nutrition not only to scientist in academia and industry and students in all food related fields as a valuable and easily used reference... it wll most likely be the first book I reach for when the inevitable question arises.April 1994Price: 115.00UK
The papers in this book were presented at the Third International Symposium on Redox Mechanisms and Interfacial Properties of Molecules of Biological Importance held in Honolulu, Hawaii between October 19-23, 1987. This Symposium was held as part of the 172nd Meeting of The Electrochemical Society which was cosponsored by The Electrochemical Society of Japan with the cooperation of The Japan Society of Applied Physics. The aim of the Symposium was to bring together a group of electrochemists and bio-medical scientists with interests in electrochemistry from around the world to present their most current research results and/or to present up-to-date reviews of current areas of research activity. It is quite clear from the diversity of topics covered in the various papers that electrochemistry and electrochemical techniques and principles have much to contribute to our under standing of many important biochemical phenomena. For example, electrochemical studies are providing important insights into the redox properties of biomolecules ranging from relatively small organic molecules such as indoleamine neurotransmitters to very large organic/organometallic molecules which include various redox enzymes or model enzyme systems. Many of the most powerful analytical techniques are now being coupled to electrodes to monitor potential-controlled behaviors of bio logical molecules at charged interfaces. Electrochemical techniques are now being developed which permit extraordinarily small electrodes to be inserted into single cells to monitor electroactive biomolecules. Other microelectrodes are being employed to control cell growth and to manipulate single cells.
Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. Macromolecules, essentially nucleic acids, proteins and complex carbohydrates, are the building blocks of cell structure and function. This fifth volume in the "Bioelectrochemistry" series deals essentially with water-soluble biomacromolecules, since the properties of membrane-bound proteins are considered in other volumes of this series. The first chapter provides an extensive review of the structure, chemical reactivity and electromagnetic properties of nucleic acids. The following five chapters concentrate on proteins, their structure, folding and function, the electrochemistry of redox proteins and voltammetric methods. Special attention is devoted to the field of thiol/disulfide exchange as well as to one particular class of proteins, the iron-sulfur proteins. The last chapter considers the chemistry and properties of glycosaminoglycans, the complex charged polysaccharides of the cell surface and extracellular matrix. This series is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.
