Capillary Electrophoresis

This book examines challenges and applications, as well as principles of capillary electrophoresis. Some of the topics discusses include the preparation and application of photosensitive capillary electrophoresis coatings; the application of capillary zone electrophoresis to trace analyses of inorganic anions in seawater; theoretical principles and applications of high performance capillary electrophoresis; and the application of capillary zone electrophoresis methods for polyphenols and organic acids to separate different extracts.

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

Novices to the field will find this book an easy-to-follow introduction to core capillary electrophoresis techniques and methods. More experienced investigators can turn to the book for troubleshooting tips and expert advice to guide them through the most advanced applications.

The best source of practical, easily accessible information on this exciting new technique CAPILLARY ELECTROPHORESIS Analytical chemists and biochemists have been turning to the technique of capillary electrophoresis with increasing frequency: it is fast, sensitive, easy to automate, requires only small sample volumes and reagent amounts, and has been successfully applied to an ever-expanding list of sample types. In Capillary Electrophoresis, analytical practitioners will find a complete, practical guide to the principles, forms, and instrumentation of this technique. The book presents clear and straightforward explanations of the method, its operating principles, and its different modes, including capillary zone electrophoresis, micellar electrokinetic capillary chromatography, capillary gel electrophoresis, capillary isoelectric focusing, and capillary isotachophoresis. Especially helpful is the material on developing a method: it offers practical guidance on CE modes, capillaries, run buffers, voltage requirements, sample pretreatments, injection modes and amounts, temperature settings, detector selections, buffer replenishment, and data reporting.

Capillary electrophoresis (CE) is a brand-new analytical me- thod with the capability of solving many analytical separa- tion problems very fast and economically. This method gives new information about the investigated substances which can- not easily be obtained by other means. CE has become an established method only recently, but will be implemented in almost every analytical laboratory in industry, service units and academia in the near future. The most important fields of CE application are pharmaceutical and biochemical research and quality control. The authors have exhaustive practical experience in the application of CE methods in the pharmaceutical industry and provide the reader with a comprehensive treatment of this method. The main focus is on how to solve problems when applying CE in the laboratory. Physico-chemical theory is only dealt with in depth when necessary to understand the underlying separation mechanisms in order to solve your problems at the analytical bench. An addendum includes tables on the preparation of buffers and recommended further reading.
