Gas chromatography is widely used in applications involving food analysis. Typical applications pertain to the quantitative and/or qualitative analysis of food composition, natural products, food additives, and flavour and aroma components. Providing an up-to-date look at the significant advances in the technology, this book includes details on novel sample preparation processes; conventional, high-speed multidimensional gas chromatography systems, including preparative instrumentation; gas chromatography–olfactometry principles; and, finally, chemometrics principles and applications in food analysis. Aimed at providing the food researcher or analyst with detailed analytical information related to advanced gas chromatography technologies, this book is suitable for professionals and postgraduate students learning about the technique in the food industry and research.

The food analyst plays an important role in modern society. Stricter control over additives in food and concern about the effects of contamination of food by industrial and agricultural chemicals are among the developments which are leading to an increasing emphasis on detailed and accurate analysis of food. However. analysis of food is required for many reasons, including detection of toxic components, monitoring legislation, detecting adulteration, formulation of controlled diets, controlling formulation during product development and detecting changes in food during storage and processing. Foods comprise a complex mixture of components and food analysis requires efficient methods of separation with high sensitivity or specificity of detection. Although many food components are involatile or thermally labile and therefore not suitable for analysis by gas chromatography, other components are volatile and this technique is the preferred analytical method. Developments in methods of derivati zation, injector design and column technology have also extended the applicability of gas chromatography to the analysis of relatively involatile compounds.

Analytical techniques based on separation processes, such as chromatography and electrophoresis, are finding a growing range of applications in chemical, pharmaceutical and clinical laboratories. This series provides the analyst in these laboratories with well focused books covering individual techniques, so that they can be applied more efficiently and effectively to contemporary analytical problems. Capillary gas chromatography is one of the most powerful separation tools available to analysts working in a wide diversity of disciplines. Capillary Gas Chromatography will give practising analysts a sound theoretical and practical knowledge of the subject, giving a thorough account of the many fascinating and important developments occurring in the field in recent years. The theory is presented with practical applications in mind. Common problems encountered when using this technique, and the means of overcoming them are also presented. Capillary Gas Chromatography will be of great practical use to analytical chemists using the technique, including those in the pharmaceutical, food and beverage, environmental, clinical, and petrochemical industries. It will also be invaluable for graduate students and researchers involved in the need to separate complex mixtures.

Gas chromatography mass spectrometry (GC-MS) has been the technique of choice of analytical scientists for many years. The latest developments in instrumentation, including tandem mass spectrometry (MS-MS) and time-of-flight (TOF) detectors, have opened up and broadened the scope of environmental analytical chemistry. This book summarizes the major advances and relevant applications of GC-MS techniques over the last 10 years, with chapters by leading authors in the field of environmental chemistry. The authors are drawn from academia, industry and government. The book is organized in three main parts. Part I covers applications of basic GC-MS to solve environmental-related problems. Part II focuses on GC-MS-MS instrumentation for the analyses of a broad range of analysis in environmental samples (pesticides, persistent organic pollutants, endocrine disruptors, etc.). Part III covers the use of more advanced GC-MS techniques using low- and high-resolution mass spectrometry for many applications related to the environment, food and industry. - Summarizes the major advances of GC-MS techniques in the last decade - Presents relevant applications of GC-MS techniques - Covers academic, industrial and governmental sectors

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.

This book provides a critical overview of analytical methods used for the determination of pesticide residues and other contaminants in food and environmental samples by modern instrumental analysis. It contains up-to-date material including recent trends in sample preparation, general methods used for pesticide analysis and quality assurance aspects, and chromatographic and immunoassay methods. The rest of the book describes particular analytical methods used for the determination of pesticides in food and soil, water and air. In addition, the levels of these chemicals found in food, their regulatory aspects and the monitoring of pesticides in the environment are described.
