The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guide follows the highly successful first edition by F.G. Kitson, B.S. Larsen, and C.N. McEwen (1996), which was designed as an indispensible resource for GC/MS practitioners regardless of whether they are a novice or well experienced. The Fundamentals section has been extensively reworked from the original edition to give more depth of an understanding of the techniques and science involved with GC/MS. Even with this expansion, the original brevity and simple didactic style has been retained. Information on chromatographic peak deconvolution has been added along with a more in-depth understanding of the use of mass spectral databases in the identification of unknowns. Since the last edition, a number of advances in GC inlet systems and sample introduction techniques have occurred, and they are included in the new edition. Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass Spectral Interpretation of Specific Compound Types has the same number of compound types as the original edition, but the information in each section has been expanded to not only explain some of the spectra but to also explain why certain fragmentations take place. The number of Appendices has been increased from 12 to 17. The Appendix on Atomic Masses and Isotope Abundances has been expanded to provide tools to aid in determination of elemental composition from isotope peak intensity ratios. An appendix with examples on "Steps to follow in the determination of elemental compositions based on isotope peak intensities" has been added. Appendices on whether to use GC/MS or LC/MS, third-party software for use in data analysis, list of information required in reporting GC/MS data, X+1 and X+2 peak relative intensities based on the number of atoms of carbon in an ion, and list of available EI mass spectral databases have been added. Others such as the ones on derivatization, isotope peak patterns for ions with Cl and/or Br, terms used in GC and in mass spectrometry, and tips on setting up, maintaining and troubleshooting a GC/MS system have all been expanded and updated. Covers the practical instruction necessary for successful operation of GC/MS equipment Reviews the latest advances in instrumentation, ionization methods, and quantitation Includes troubleshooting techniques and a variety of additional information useful for the GC/MS practitioner A true benchtop reference A guide to a basic understanding of the components of a Gas Chromatograph-Mass Spectrometer (GC-MS) Quick References to data interpretation Ready source for information on new analyses

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.

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

Updated to reflect changes in the industry during the last ten years, The Handbook of Food Analysis, Third Edition covers the new analysis systems, optimization of existing techniques, and automation and miniaturization methods. Under the editorial guidance of food science pioneer Leo M.L. Nollet and new editor Fidel Toldra, the chapters take an in-depth look at how to determine the chemical composition of foodstuffs at the level required to safeguard consumer health, well-being, and safety. See What’s New in the Third Edition: Discussions of analysis techniques of rheological, thermal, and flavor properties of food Examination of methods and techniques in food analysis Coverage amines, flavorings, and food traceability Unparalleled in breadth and depth, the set delineates the physical and chemical properties of nutrients and other food components. It presents an exhaustive compilation of analytical methods and provides step-by-step descriptions of preparation, detection, separation, derivatization, and clean-up techniques. It also assesses the relative advantage, accuracy, and reliability of each procedure. Volume 1 covers Physical and Sensory Properties; Additives, Adulteration, and Traceability; and Nutritional Analysis while Volume 2 covers Residues and Other Food Components; as well as Methods, Techniques, and Instruments. Together the two volumes examine both parts of food analysis: analytical and quantitative testing of product composition and guaranteeing product quality and safety as productivity increases. These volumes give you the analytical foundation required to develop food products free from contaminants and toxins and the tools to control their safety.

A unique practical guide to building, using, and maintaining a complete GC/MS system. Though gas chromatography/mass spectrometry (GC/MS) is one of the most effective and popular methods of separating, identifying, and quantifying compounds in complex mixtures, there have been no comprehensive handbooks to date that clearly explain the setup and maintenance of a functional GC/MS system. Now Marvin and Christopher McMaster have created the hands-on resource that researchers and students need to get their own systems up and running quickly. Covering everything from necessary components to tuning, troubleshooting, and processing data, it allows even those with little prior knowledge of GC/MS to perform their own analyses and gather the data they require. GC/MS: A Practical User's Guide contains: * Full coverage of vital equipment, including the function, costs, and advantages of both desktop and floor-standing systems * A walkthrough of a basic GC/MS analysis and an examination of key methods of structural data interpretation * Extensive information on GC/MS system optimization * An exploration of the various research and environmental uses of GC/MS systems * An extended section on liquid chromatography/mass spectrometry to enhance comprehension of the gas method. For organic, analytical, clinical, environmental, and forensic chemists in all types of laboratories-and for students in all of these specialties -this book will be an invaluable companion for years to come.
