Recently there has been a great deal written about the benefits capillary chromatography offers in the area of separation and analysis. However, there is a need now to focus on the detection methods commonly used with capillary chromatography. Detectors for Capillary Chromatography presents the writings of 20 authorities who describe the unique features of each detector that are required for successful interfacing with capillary columns. Fused silica column technology has now advanced to the point where tremendous separation power is available. However, as these chapters show, without the ability to "see" the separated components, this high resolution is wasted. While it is true that the column is the heart of the chromatographic process, the detectors are the "eyes" that make the separation visible. A number of methods for "looking" at the results of chromatographic separations have been developed and each provides a different "view". To understand the information gained in high resolution chromatography, you must be able to interpret correctly the view provided by the detector. This book will provide you with the necessary insights into how you can accomplish that. The outstanding contributors to this book are all experts in the field. In many cases they are the researchers who originally developed the detector or have made major contributions to understanding its operation. This state-of-the-art text will be of immediate benefit to analytical chemists and physical chemists worKing with gas chromatography, who use this technique in environmental, industrial, or forensic investigations.

The only reference to provide both current and thorough coverage of this important analytical technique Static headspace-gas chromatography (HS-GC) is an indispensable technique for analyzing volatile organic compounds, enabling the analyst to assay a variety of sample matrices while avoiding the costly and time-consuming preparation involved with traditional GC. Static Headspace-Gas Chromatography: Theory and Practice has long been the only reference to provide in-depth coverage of this method of analysis. The Second Edition has been thoroughly updated to reflect the most recent developments and practices, and also includes coverage of solid-phase microextraction (SPME) and the purge-and-trap technique. Chapters cover: * Principles of static and dynamic headspace analysis, including the evolution of HS-GC methods and regulatory methods using static HS-GC * Basic theory of headspace analysis-physicochemical relationships, sensitivity, and the principles of multiple headspace extraction * HS-GC techniques-vials, cleaning, caps, sample volume, enrichment, and cryogenic techniques * Sample handling * Cryogenic HS-GC * Method development in HS-GC * Nonequilibrium static headspace analysis * Determination of physicochemical functions such as vapor pressures, activity coefficients, and more Comprehensive and focused, Static Headspace-Gas Chromatography, Second Edition provides an excellent resource to help the reader achieve optimal chromatographic results. Practical examples with original data help readers to master determinations in a wide variety of areas, such as forensic, environmental, pharmaceutical, and industrial applications.

Choosing the right column is key in Gas Chromatography Gas Chromatography (GC) is the most widely used method for separating and analyzing a wide variety of organic compounds and gases. There have been many recent advancements in both packed column and capillary column GC. With numerous options and considerations, selecting the right column can be complicated. This resource provides essential guidance for scientists and technicians, including: Methods of choosing both capillary and packed columns Selection of dimensions (column length, I.D., film thickness, etc.) and type of column Guidelines for proper connections of the column to the injector and detector United States Pharmacopeia and National Formulary chromatographic methods ASTM, EPA, NIOSH, and OSHA column selection specifications Information on the advantages of computer assistance in GC and multidimensional GC Comprehensive information on column oven temperature control Columns for Gas Chromatography: Performance and Selection is a hands-on reference for scientists and technicians using GC.

THE remarkable capabilities of capillary gas partition chromatography (or, in short, capillary chromatography) are beyond all doubt. In spite of this, difficulties are continually arising in the experimental realization of this interesting development of gas chromatography, and this hinders the rapid acceptance of these methods. For this reason, in the present work I have dealt with experimental and practical problems rather than with theoretical aspects, hoping that this may serve to remove many of the problems con cerned. The present publication is based on experimental work carried out in productive collaboration with my teachers and colleagues, to whom I owe a great deal. I should like to thank the following for their valuable assistance and stimulating suggestions: Professor E. Cremer, Dr. H. Kienitz and his colleagues, Professor A. I. M. Keulemans, Dr. I. Halasz, and in particular Mr. D. H. Desty and Dr. R. P. W. Scott. I should also like to thank the management of the Badische Anilin- und Sodafabrik AG, Ludwigshafen, for their generous support and for per mission to publish this book. The outstanding co-operation of the Verlag Bibliographisches Institut, Mannheim, was for me a particular pleasure.

Qualitative Analysis of Flavor and Fragrance Volatiles by Glass Capillary Gas Chromatography deals with the application of glass capillary gas chromatography to qualitative analysis of flavor and fragrance volatiles. Topics range from gas chromatographic system requirements and retention indices to selective detectors, ancillary reactions, and gas chromatography-mass spectrometry. This text is comprised of six chapters; the first of which provides an overview of the use of glass capillary gas chromatography in qualitative analysis of flavor and fragrance volatiles. The discussion then turns to gas chromatographic system requirements with respect to columns, inlets, detectors, and temperature control. The reader is also introduced to the Kovats retention index system, which utilizes a logarithmic scale to describe the retention behavior of a compound relative to that of the n-paraffin hydrocarbons. The use of selective detectors, such as thermal conductivity, flame ionization, nitrogen-phosphorus, electron capture, and photoionization detectors in qualitative analysis, is also considered. The final two chapters focus on ancillary reactions in glass capillary gas chromatography and general considerations in gas chromatography-mass spectrometry, including interfacing. This book is intended primarily for researchers involved in studies of the volatile constituents of fragrances, food, and natural products.
