In the rapidly developing field of analysis it is important to be aware of the newest methods within available techniques. Chromatography and Capillary Electrophoresis in Food Analysis describes chromatographic and electrophoretic principles and procedures for analyses of various amphiphilic and hydrophilic biomolecules, particularly for food analysis. Providing basic information, including general sample preparation, the book then goes on to describe individual analytical methods and exemplify the strategy and methodologies employed for the analyses. The theory necessary to understand the methods and interpretation of results is also included, as are numerous detailed instructions on experiments. Tables, figures and references are included to give a complete picture. Chromatography and Capillary Electrophoresis in Food Analysis will be especially valuable for students and more experienced researchers interested in analysis of natural products, both inside and outside the field of food chemistry.

Over the last decade, high performance Capillary electrophoresis (HPCE) has emerged as a powerful and versatile separation technique that promises to rival high performance liquid chromatography when applied to the separation of both charged and neutral species. The high speed and high separation efficiency which can be attained using any of the various modes of HPCE has resulted in the increased use of the technique in a range of analytical environments. The procedures are, however, still in the early stages of development and several barriers remain to their adoption as the technique of choice for a range of analytical problems. One such barrier is the selection and optimization of the conditions required to achieve reproducible separations of analytes and it is in this area that this new book seeks to give assistance. The book is written by an international team of authors, drawn from both academic and industrial users, and the manufacturers of instruments. At its heart are a number of tables, divided into specific application areas. These give details of published separations of a wide range of archetypal analytes, the successful separation conditions and the matrix in which they were presented. These tables are based on separations reported since 1992 and are fully referenced to the original literature. The tables are supported by discussions of the problems that a particular area presents and the strategies and solutions adopted to overcome them. The general areas covered are biochemistry, pharmaceutical science, bioscience, ion analysis, food analysis and environmental science.

Capillary electrophoresis (CE) comprises a family of related separation techniques in which an electric field is used to achieve the separation of components in a mixture. One of the key features of CE is the simplicity of the instrumentation required, and today, these techniques have become powerful analytical tools for high efficiency separation, and the identification of a variety of ionic and neutral compounds. Moreover, the versatility of CE operational modes (capillary zone electrophoresis, micellar electrokinetic capillary chromatography, capillary electrochromatography, capillary isoelectric focusing, isotachophoresis, non-aqueous capillary electrophoresis, etc.) and detection systems (ultraviolet, fluorescence, amperometric, mass spectrometry...) make CE useful for applications in many fields such as environmental, food, pharmaceutical, and forensic analysis. The typcial drawback of CE techniques, based on their low sensitivity when dealing with conventional UV-detection, due to their short detection pathways and the short sample volume introduced into the capillary, has been largely resolved not only by using more sensitive detectors like fluorescence, amperometric, or mass spectrometry, but by the employment of both off-line and on-line enrichment procedures. The aim of this present book is to address the state-of-the art of capillary electrophoresis techniques within this early twenty-first century, by reviewing new trends and the most relevant applications described in the literature. Uses in fields such as food, environmental, forensic and biological analysis are addressed by means of relevant application. The scope of this book is intentionally broad and is aimed at worldwide analytical laboratories, both public and private, at acadamic institutions, as well as researchers.

High performance capillary electrophoresis (HPCE) is the newest and perhaps most powerful separation technique available today. This single-authored text provides an integrated, comprehensive, and clearly illustrated look at the field. Users of HPCE will gain a basic understanding of principles underlying electrophoresis and go on to learn about mode selection, methods development, detection, and quantative analysis. Ideally suited for analytical chemists and analytical biochemists with applications involving small molecules, proteins, peptides, DNA, and ion separations, this book provides a comparative assessment of related techniques. The author is an internationally recognised scientist and serves as the instructor for short courses on HPCE as offered by the American Chemical Society.* Stresses basic principles and applications* Helps users select appropriate HPCE modes and develop methods* Describes how to perform quantitative analyses* reinforces concepts with clear illustrations

This text aims to evaluate the actual impact of high-performance capillary electrophoresis on analytical biotechnology and environmental analysis. The first part of the book presents a survey of present innovations in instrument design and different methods of pre-concentration techniques in order to obtain increased separations at higher sensitivities. The second part contains articles on applications of HPCE to protein and peptide analysis. In the third part, applications of HPCE in the investigation of drug abuse and drug interactions are presented. The last two parts of the book deal with the use of HPCE at low-UV wavelengths and negative-UV absorption. The book should be of interest to those working in HPCE research and applications.

In the 1980s, capillary electrophoresis (CE) joined high-performance liquid chromatography (HPLC) as the most powerful separation technique available to analytical chemists and biochemists. Published research using CE grew from 48 papers in the year of commercial introduction (1988) to 1200 in 1997. While only a dozen major pharmaceutical and biotech companies have reduced CE to routine practice, the applications market is showing real or potential growth in key areas, particularly in the DNA marketplace for genomic mapping and forensic identification. For drug development involving small molecules (including chiral separations), one CE instrument can replace 10 liquid chromatographs in terms of speed of analysis. CE also uses aqueous rather than organic solvents and is thus environmentally friendlier than HPLC. The second edition of Practical Capillary Electrophoresis has been extensively reorganized and rewritten to reflect modern usage in the field, with an emphasis on commercially available apparatus and reagents. This authoritative and very comprehensible treatment builds on the author's extensive experience as an instructor of short courses for the American Chemical Society and for industry. - Illustrated with detailed diagrams of electrophoretic phenomena - Offers step-by-step methods development schemes - Presents techniques for developing quantitative, robust, and precise methods - Includes an extensive troubleshooting guide - Updates and greatly expands on the first edition-more than 50% of the text is new - Written by an internationally recognized scientist who is an instructor for American Chemical Society short courses on HPCE

Die Kapillarelektrophorese (CE) ist heute in biochemischen Laboratorien noch nicht als Routinemethode zur DNA-Trennung etabliert, obwohl sie diverse Vorzüge gegenüber den derzeitigen Methoden besitzt. In diesem Band stellen verschiedene Wissenschaftler die theoretischen Aspekte der Trennung von Oligonucleinsäuren mit der CE, die instrumentellen Grundlagen und deren Grenzen und schließlich die praktische Anwendung in der Biochemie und Molekularbiologie vor. This book on capillary electrophoresis is unique in its focus on the separation of nucleic acids. The importance of electrophoretic separation in every molecular biology laboratory justifies this specialization, which is also reflected in the development of instrumentation. This book is aimed to help to implement this rather new and promising technology in the biological laboratories and to help to overcome typical problems that can occur when starting with a new technique. It should also trigger further development in the field. It covers the theoretical background as well as practical examples of usual applications. The authors are all experts in their field, having many years of experience with capillary electrophoresis and their application to nucleic acids.
