This practical guide provides a basic overview of the pros and cons of NMR spectroscopy as both a hyphenated and non-hyphenated technique. The book begins with a description of basic NMR concepts for the structural elucidation of organic compounds and then details the historical development of NMR and hyphenated NMR in the structural elucidation world, followed by applications of hyphenated NMR as LC-NMR and LC-MS-NMR in industry and academia. It also contains updated information on the latest advancements and applications of LC-NMR in such areas as degradation products, drug metabolism, food analysis, and drug discovery. An essential resource for scientists in industry and academia who work in the areas of organic chemistry, medicinal chemistry, process chemistry, and analytical chemistry.

The isolation and structural characterization of substances present at very low concentrations, as is necessary to satisfy regulatory requirements for pharmaceutical drug degradants and impurities, can present scientific challenges. The coupling of HPLC with NMR spectroscopy has been at the forefront of cutting-edge technologies to address these is

The powerful, efficient technique of high performance liquid chromatography (HPLC) is essential to the standardization of plant-based drugs, identification of plant material, and creation of new herbal medicines. Filling the void in this critical area, High Performance Liquid Chromatography in Phytochemical Analysis is the first book to give a comp

This book gives a comprehensive overview of the basis and the current applications of LC-NMR and related techniques. It deals with the practical aspects of the hardware and software set-up for a successful performance of on-line coupling experiments. It covers the solution of real-word problems from the fields of biomedical, pharmaceutical and environmental studies as well as the analysis of natural products and polymeric compounds. Thus guidelines for an efficient application of the powerful hyphenated technique LC-NMR in combination with LC-MS are presented. Besides LC-NMR, important techniques such as the on-line coupling of gel permeation chromatography and supercritical fluid chromatography, together with 1H NMR spectroscopy, are described in detail. Fascinating further aspects, such as the application of capillary separation techniques either in the single or parallel detection mode, together with the possibilities of direct 13C monitoring of chromatographic events, are also discussed. Key features include: * Up-to-date information on the theoretical and experimental methodology * Coverage of applications in biomedical, pharmaceutical and natural product analysis, as well as environmental polymer and related hyphenated techniques * Information appropriate for researchers in organic, pharmaceutical and medical chemistry Overall, this book is a requirement for all researchers and staff members dealing with structure elucidation problems in separation science.
