Book Description
This sixth volume in the book series Progress in HPLC-HPCE examines the enhancement of high- performance liquid chromatography through the development of an advanced mode of electrochemical detection (ECD) --- the coulometric array detection --- from its initial, yet problematic, amperometric (thin-layer) design to the highly sensitive, selective and stable coulometric (flow-through) design. Unlike amperometric electrodes, the coulometric electrode is 100% efficient and measures signals from all of the analyte passing through it, which leads to improved sensitivity as well as unique selectivity. The coulometric electrode array offers the resolution of the photodiode array with the extreme sensitivity of an electrochemical detector.

Book Description
Electrochemical Detection in HPLC: Analysis of Drugs and Poisons is the first monograph devoted to the application of this mode of analysis to the assay of exogenous compounds such as drugs in biological fluids and associated areas. The introductory chapters provide information on basic electrochemistry and HPLC-ED, and on trouble-shooting. The specialized area of thiol analysis is also discussed in detail. Salient practical details of published applications of the technique in analytical toxicology and related areas are provided in a standard format. Alternative techniques are suggested throughout. The emphasis is on the analysis of exogenous compounds, although catecholamines and other endogenous species are discussed in so far as they may be used as drugs. The practical nature of this book will make it useful to professionals working in the field. It will also be of benefit to analysts wishing to use HPLC-ED in the analysis of biological samples for analytes not specifically covered in the volume.

Book Description
The first protocols book, Free Radical and Antioxidant Protocols (1) was published in late 1998. Sections were divided into three parts, covering selected biochemical techniques for measuring oxidative stress, antioxidant (AOX) activity, and combined applications. In choosing the 40 methods to be included in that book, I realized there were considerably more of equal value than that which we could have presented in a single volume. To produce a comprehensive resource, this book and a third are being compiled to expand coverage of the field. A summary of papers (2) published on this important subject emphasizes the continuing rapid growth in oxidative stress investigations relating to our understanding of biochemical reactions, their relevance to pathophysiological mechanisms, how disease may arise, and how therapeutic intervention may be achieved(3). Although there is some overlap between the categories, the ana- sis shown below illustrates where current studies are concentrated and are almost evenly distributed between free radicals and AOX. Over the last 4 yr, there has been a 55% increase in the number of papers published in the area.

Book Description
Agricultural and Food Electroanalysis offers a comprehensive rationale of electroanalysis, revealing its enormous potential in agricultural food analysis. A unique approach is used which fills a gap in the literature by bringing in applications to everyday problems. This timely text presents in-depth descriptions about different electrochemical techniques following their basic principles, instrumentation and main applications. Such techniques offer invaluable features such as inherent miniaturization, high sensitivity and selectivity, low cost, independence of sample turbidity, high compatibility with modern technologies such as microchips and biosensors, and the use of exciting nanomaterials such as nanoparticles, nanotubes and nanowires. Due to the advantages that modern electroanalytical techniques bring to food analysis, and the huge importance and emphasis given today to food quality and safety, this comprehensive work will be an essential read for professionals and researchers working in analytical laboratories and development departments, and a valuable guide for students studying for careers in food science, technology and chemistry.

Book Description
From beef to baked goods, fish to flour, antioxidants are added to preserve the shelf life of foods and ensure consumer acceptability. These production-added components may also contribute to the overall availability of essential nutrients for intake as well as the prevention of the development of unwelcome product characteristics such as off-flavours or colours. However, there are processes that reduce the amount of naturally occurring antioxidants and awareness of that potential is just as important for those in product research and development. There is a practical need to understand not only the physiological importance of antioxidants in terms of consumer health benefit, but how they may be damaged or enhanced through the processing and packaging phases. This book presents information key to understanding how antioxidants change during production of a wide variety of food products, with a focus toward how this understanding may be translated effectively to other foods as well. - Addresses how the composition of food is altered, the analytical techniques used, and the applications to other foods - Presents in-chapter summary points and other translational insights into concepts, techniques, findings and approaches to processing of other foods - Explores advances in analytical and methodological science within each chapter
