Gas chromatography-mass spectrometry (GC-MS) with supersonic molecular beams (SMB) (also named GC-MS with Cold EI) is based on GC and MS interface with a SMB and on the electron ionization (EI) of vibrationally cold analytes in the SMB (hence the name Cold EI) in a contact-free fly-through ion source. Cold EI improves all the central GC-MS performance aspects and brings a broad range of important benefits thereby leading the way to the future of GC-MS. Cold EI provides enhanced molecular ions combined with effective library-basedsample identification. Sample identification is further improved by the use of powerful TAMI software that is based on isotope abundance analysis and improved quadrupole mass accuracy for the provision of the sample elemental formula from its molecular ion group of isotopologues.

This book reviews the latest advances in mass spectrometry (MS) techniques applied to food safety and environment quality, and it discusses the recent improvements in sample preparation and MS platforms for screening of emerging contaminants. Expert contributors discuss the current applications from omics to the screening of emerging contaminants and nanomaterials in food and environmental matrices, and particular attention is given to the opportunities that MS offers for guarantying food security and promoting the sustainable use of ecosystems. Divided into 13 chapters, the book covers topics such as the handling and preparation of food and environmental samples for MS, foodomics, environmental omics, ambient ionization techniques in food and environmental chemistry, and chip-based separation devices coupled to MS. Readers will also find a comprehensive overview of several MS techniques applied to food and environmental chemistry, including elemental, isotopic, chiral, ion mobility, chromatographic and imaging MS. This book will appeal not only to students and researchers, but also to professionals working with MS platforms in food safety and environmental quality. The different advances and promising applications described in this work will be of paramount importance for ensuring food safety and environment health for current and future generations.

"In full colour throughout, this book describes the power of mass spectrometry in resolving environmental issues, demonstrating how real-world complex problems can be solved in a simple and elegant way."--Worldcat.

This comprehensive and unique handbook of split and splitless injection techniques has been completely revised and updated. This new edition offers: - New insights concerning sample evaporation in the injector - Information about matrix effects - A new chapter on injector design The real processes within the injector are for the first time visualized and explained by the CD-ROM included in the book. Furthermore the reader will understand the concepts of injection techniques and get a knowledge of the sources of error. The handbook also includes many practical guidelines. From reviews of former editions: "This substantial book is on injection techniques alone, which ... demonstrates this can have many pitfalls ... no one should be allowed to direct a laboratory doing quantitative analysis by GC without first being thoroughly familar with this book ..." The Analyst "This is a detailed reference volume filled with practical suggestions and techniques for managing split and splitless injection in the day-to-day world of the working gas chromatographer. It will be useful ... for anyone who must work hands-on with GC." Journal of High Resolution Chromatography

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

This is the first comprehensive reference work for GC/MS now in its second edition. It offers broad coverage, from sample preparation to the evaluation of MS-Data, including library searches. Fundamentals, techniques, and applications are described. A large part of the book is devoted to numerous examples for GC/MS-applications in environmental, food, pharmaceutical and clinical analysis. These proven examples come from the daily practice of various laboratories. The book also features a glossary of terms and a substance index that helps the reader to find information for his particular analytical problem. The author presents in a consistent and clear style his experience from numerous user workshops which he has organized. This is a thoroughly revised and updated English edition based on an edition which was highly successful in Germany.
