Microcolumn Separations: Columns, Instrumentation and Anchillary Techniques (Journal of Chromatography Library)

It is now well established that although micro-column liquid chromatography and associated analytical techniques can present operational problems, they do offer a number of advantages over their equivalent conventional procedures. Many of the recent developments in the field have originated in American and Japanese laboratories. In order to coordinate these efforts an informal exchange of ideas, manuscripts and personnel between the laboratories of Milos Novotny and Daido Ishii, both well respected authorities, has been in existence since 1976. In 1982 a joint conference was arranged between the two countries in order to discuss advances in the field of micro-column separation methods and compatible ancillary techniques, and also to outline future potential directions. Although this volume is a direct result of this seminar, it is not a collection of the original presentations but rather an attempt by the co-Editors to provide a balanced treatment of the current situation in the field of micro-column

separations. A total of 18 chapters are presented, divided into four sections. The first section covers column studies and includes open-tubular, packed capillary and size-exclusion microcolumns. Methods for the preparation of these columns are detailed together with some examples of the excellent separation efficiencies that can be achieved. The next section deals with miniaturised systems and specifically the critical importance of extra-column band roadening in microcolumn techniques. Systems for fast analysis, capillary supercritical fluid chromatography and capillary zone electrophoresis are also described. The third section covers spectroscopic detection, including optical, infrared, laser and flame detectors. The particularly interesting use of micro-columns with mass spectrometry receives coverage in two chapters, one specifically devoted to the various interfacing techniques. The final section on electrochemical detection covers ion chromatography, voltammetric and potentiometric detection. Although much of the information in this book could be obtained by a comprehensive literature search, it is useful to find it collected together in one volume. Many of the advances in the field of micro-column separations have been documented by the very people who first reported them. Although a multi-authored book will always be somewhat variable in quality, the general standard in this volume is high, giving a very comprehensive and readable coverage of the field. Some,chapters are prefaced by a short abstract, a very useful feature that was unfortunately not always adopted. A reasonable

index is provided. The illustrations are always clear and of good quality. This book will provide a useful reference volumz for anyone interested in the subject uf micro-column separations. C. R. Loscombe Buy Book at Lowest Price on Amazon
