This book gives a comprehensive, up-to-date review of all selective detectors used in combination with gas chromatography. For each detector, the historical background, design and principle are described, and the working parameters affecting the detector performance are analyzed critically and in detail. The analytical possibilities of the detectors and the main characteristics such as sensitivity, noise and minimum detectability are discussed. All the selective detectors that are currently used are discussed in detail. Combinations of GC with other techniques such as plasma emission spectroscopy, atomic absorption spectrometry, ion-selective electrodes, piezoelectric sorption detector, mass spectrometry and infrared spectroscopy are discussed briefly.Chromatographers and users of gas chromatographs, especially in the field of environmental protection, agriculture, clinical chemistry, and toxicology will find the book useful to their work. Institutes and organisations dealing with analytical chemistry will also find it of interest.

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.

Gas chromatography continues to be one of the most widely used analytical techniques, since its applications today expand into fields such as biomarker research or metabolomics. This new practical textbook enables the reader to make full use of gas chromatography. Essential fundamentals and their implications for the practical work at the instrument are provided, as well as details on the instrumentation such as inlet systems, columns and detectors. Specialized techniques from all aspects of GC are introduced ranging from sample preparation, solvent-free injection techniques, and pyrolysis GC, to separation including fast GC and comprehensive GCxGC and finally detection, such as GC-MS and element-specific detection. Various fields of application such as enantiomer, food, flavor and fragrance analysis, physicochemical measurements, forensic toxicology, and clinical analysis are discussed as well as cutting-edge application in metabolomics is covered.

Analytical Gas Chromatography is a free-standing introduction to and guide through the rapidly progressing field of analytical gas chromatography. The book is divided into 10 chapters that cover various aspects of analytical gas chromatography, from most advantageous column type to troubleshooting. The opening chapters of the book discuss the advantages of the open tubular column over the packed column. This topic is followed by significant chapters on various variables in the gas chromatographic process, including sample injection, stationary phase, carrier gas, and installation. The effect of changes in these variables on the solution elution order is also considered. A chapter also examines the influence of instrumental design features, such as excessive or unswept volumes in the flow path; suitability of the detection mode; and speed and fidelity of the data-handling equipment. The book also presents selected methods that have been employed to achieve better results for a given gas chromatographic problem. The application areas of gas chromatographic process, including food, flavor, fragrance, petroleum- and chemical-related, environment, biology, and medicine, are also presented. The concluding chapter addresses the basic troubleshooting knowledge and considers other chromatographic problems and methods for their rectification.

The threat of domestic terrorism today looms larger than ever. Bombings at the World Trade Center and Oklahoma City's Federal Building, as well as nerve gas attacks in Japan, have made it tragically obvious that American civilians must be ready for terrorist attacks. What do we need to know to help emergency and medical personnel prepare for these attacks? Chemical and Biological Terrorism identifies the R&D efforts needed to implement recommendations in key areas: pre-incident intelligence, detection and identification of chemical and biological agents, protective clothing and equipment, early recognition that a population has been covertly exposed to a pathogen, mass casualty decontamination and triage, use of vaccines and pharmaceuticals, and the psychological effects of terror. Specific objectives for computer software development are also identified. The book addresses the differences between a biological and chemical attack, the distinct challenges to the military and civilian medical communities, and other broader issues. This book will be of critical interest to anyone involved in civilian preparedness for terrorist attack: planners, administrators, responders, medical professionals, public health and emergency personnel, and technology designers and engineers.
