Book Description
In spite of important advances in asymmetric synthesis, chiral compounds cannot all be obtained in a pure state by asymmetric synthesis. As a result, enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation methods using modern techniques developed by experts in the field. These methods consist mainly of the following three types: 1) Enantiomer separation by inclusion complexation with a chiral host compound 2) Enantiomer separation using biological methods 3) Enantiomer separation by HPLC chromatography using a column containing a chiral stationary phase. Separation of a racemic compound has been called “optical resolution” or simply “resolution”. Nowadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field.

Book Description
Handbook of Methods and Instrumentation in Separation Science, Volume 1 provides concise overviews and summaries of the main methods used for separation. It is based on the Encyclopedia of Separation Science. The handbook focuses on the principles of methods and instrumentation. It provides general concepts concerning the subject matter; it does not present specific procedures. This volume discusses the separation processes including affinity methods, analytical ultracentrifugation, centrifugation, chromatography, and use of decanter centrifuge and dye. Each methodology is defined and compared with other separation processes. It also provides specific techniques, principles, and theories concerning each process. Furthermore, the handbook presents the applications, benefits, and validation of the processes described in this book. This handbook is an excellent reference for biomedical researchers, environmental and production chemists, flavor and fragrance technologists, food and beverage technologists, academic and industrial librarians, and nuclear researchers. Students and novices will also find this handbook useful for practice and learning. One-stop source for information on separation methods General overviews for quick orientation Ease of use for finding results fast Expert coverage of major separation methods Coverage of techniques for all sizes of samples, pico-level to kilo-level

Book Description
The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book Description
Covers the Fundamentals of Chiral Separation, Available Chiral Selectors, and Numerous Applications of Chiral Separation by Capillary Electrophoresis Since 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 Capillary Electrophoresis provides a general overview of the principles of chiral separation by capillary electrophoresis and the different chiral selectors available. The book discusses the most important as well as several new chiral selectors used in capillary electrophoresis. It reviews recent pharmaceutical and biomedical applications and explores novel techniques, such as capillary electrophoresis coupled to mass spectrometry and microchip technology. The book also examines the quantitative aspects of capillary electrophoresis, the possibilities of capillary electrochromatography, and the various chiral columns available. Capillary electrophoresis has proven to be an effective tool for chiral separation. This book explains how this technique can be used in the separation of molecules, offering insight into both existing and emerging applications.
