HPLC and CE: Principles and Practice presents the latest information on the most powerful separation techniques available: high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE). Fundamental theory, instrumentation, modes of operation, and optimization of separations are presented in a concise, non-technical style to help the user in choosing the appropriate technique quickly and accurately. Well- illustrated and containing convenientend-of-chapter summaries of the major concepts, the book provides in-depth coverage of trouble-shooting, improvement of resolution, data manipulation, selectivity, and sensitivity.Graduate students, technicians, and researchers who must use separations with little or no background in analytical chemistry can overcome separation anxiety and get started in obtaining the best possible separations in minimal time. The book will alsobe useful to analytical chemists who need a better understanding of theory and processes. - Fully up-to-date information on both HPLC and CE includes troubleshooting and comparisons of the two techniques - Applicable to a wide variety of separation problems - Covers basic concepts governing any separation as well as instrumentation and how to use it - Helps the user to obtain optimal resolution in minimal time - Contains information on special procedures such as chiral separations, affinity chromatography, and sample preparation - Includes information on upcoming trends such as miniaturization - Major concepts in each chapter are organized to allow access to information easily and quickly - Contains practical bibliography for accessing the literature
The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. More than 260 volumes have been published (all of them still in print) and much of the material is relevant even today--truly an essential publication for researchers in all fields of life sciences. Key Features * Liquid chromatography * Electrophoresis * Mass spectrometry.
Carbohydrates and glycoconjugates play an important role in several life processes. The wide variety of carbohydrate species and their inherent polydispersity and heterogeneity require separation techniques of high resolving power and high selectivity such as high performance liquid chromatography (HPLC) and capillary electrophoresis (HPCE). In the last decade HPLC, and recently HPCE methods have been developed for the high resolution and reproducible quantitation of carbohydrates. Despite the importance of these two column separation technologies in the area of carbohydrates, no previous book describes specialized methods for the separation, purification and detection of carbohydrates and glycoconjugates by HPLC and HPCE.Therefore, the objective of the present book is to provide a comprehensive review of carbohydrate analysis by HPLC and HPCE by covering analytical and preparative separation techniques for all classes of carbohydrates including mono- and disaccharides; linear and cyclic oligosaccharides; branched heterooligosaccharides (e.g., glycans, plant-derived oligosaccharides); glycoconjugates (e.g., glycolipids, glycoproteins); carbohydrates in food and beverage; compositional carbohydrates of polysaccharides; carbohydrates in biomass degradation; etc.The book will be of interest to a wide audience, including analytical chemists and biochemists, carbohydrate, glycoprotein and glycolipid chemists, molecular biologists, biotechnologists, etc. It will also be a useful reference work for both the experienced analyst and the newcomer as well as for users of HPLC and HPCE, graduates and postdoctoral students.
Covers the Fundamentals of Chiral Separation, Available Chiral Selectors, and Numerous Applications of Chiral Separation by Capillary ElectrophoresisSince the 1980s, modern analytical tools have enabled capillary electrophoresis to become a standard part of the chemist's toolkit. With contributions from international experts, Chiral Separations by
Providing a source of information on the powerful separation techniques high performance liquid chromatography and capillary electrophoresis, this text presents the fundamental theory, instrumentation, modes of operation, and optimization of these separations. Also provided is coverage of troubleshooting techniques, improvement of resolution, data manipulation, selectivity, and sensitivity. Information is also included on special procedures such as chiral separations, affinity, chromatography, and sample preparation and current trends such as miniaturization.
Detection of drugs at low concentration is required in a variety of biological and medical situations, in order to avoid harmful side effects posed by some drug residues. The book details the instrumentation, detection, and application of nano chromatography (that is, any chromatographic and capillary electrophoretic method dealing with the detection of a sample at nano gram per liter or lower) and capillary electrophoresis in the analyses of biological and environmental samples. Methods discussed include: Nano Gas Chromatography, Nano Capillary Electrophoresis, Nano Chiral Chromatography, Micellar Electrokinetic Chromatography, Supercritical Fluid Chromatography, and Nano High Performance Liquid Chromatography.
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
Capillary electrophoresis (CE) is a powerful analytical technique that is widely used in research and development and in quality control of pharmaceuticals. Many reports of highly efficient separations and methods have been published over the past 15 years. CE offers several advantages over high-pressure or high-performance liquid chromatography (HPLC). These include simplicity, rapid analysis, automation, ruggedness, different mechanisms for selectivity, and low cost. Moreover, EC requires smaller sample size and yet offers higher efficiency and thus greater resolution power over HPLC. These characteristics are very attractive in research and development, even more so in pharmaceutical quality control (QC) and stability monitoring (SM) studies. This book will provide busy pharmaceutical scientists a complete yet concise reference guide for utilizing the versatility of CE in new drug development and quality control.- Provides current status and future developments in CE analysis of pharmaceuticals.- Explains how to develop and validate methods.- Includes major pharmaceutical applications including assays and impurity testing.
A Century of Separation Science presents an extensive overview of the critical developments in separation science since 1900, covering recent advances in chromatography, electrophoresis, field-flow fractionation, countercurrent chromatography, and supercritical fluid chromatography for high-speed and high-throughput analysis.
