Compound-specific Stable Isotope Analysis de Maik A. Jochmann,Torsten C. Schmidt

Descripción - Críticas Books' topic The analysis of stable isotope ratios in individual compounds is becoming an established method in the analytical chemist's toolbox. The on-line coupling of chromatographic separation and isotope ratio mass spectrometry makes it possible to identify sources and precursor materials of a target compound from isotopic fingerprints even if it is present in a complex matrix. The raising number of application of compound-specific stable isotope analysis (CSIA), for example, in (environmental) forensics, doping control, and food authentication is evidence for its increasing importance. CSIA also offers novel avenues to track, for example, transformation processes of organic groundwater contaminants, by making use of systematic variation of stable isotope compositions associated with (bio)chemical reactions. However, CSIA requires dedicated instrumentation, a lot of expert knowledge, and often years of hands-on experience. The textbook-like companion by Jochmann and Schmidt will make this method more accessible and the book is a welcome promotion for a promising analytical tool. Contents The art of CSIA is described in seven chapters. In the introductory one, the authors briefly summarize historical and instrumental developments that have led to the stateof- the art and they make the important distinction between bulk and compound-specific techniques. Chapter two is devoted to basic concepts that are applied throughout the book. A short excursion to the structure of atoms is made to define essential isotope-related terms in physical chemistry. Following the latest IUPAC definitions, expressions are given for isotope-amount fractions, isotope ratios, and the - scale with which isotope distributions at natural abundances are quantified. Terms and expressions are exemplified for the elements covered in this book, namely H, C, N, O, S, Cl, and Br. The chapter closes with derivations for the interpretation of kinetic and equilibrium isotope fractionation. Chapters 3 to 5 are the core part of the book and contain a wealth of practical information. The authors thoroughly guide readers through the essential parts of an isotope ratio mass spectrometer and its inlet systems before turning to the coupling to gas and liquid chromatography (Chapter 3). Some essential aspects of chromatography with particular relevance for isotopic analyses are reviewed here. Chapter 4 is devoted to sample preparation and includes a discussion of strategies for organic compound derivatization. Chapter 5 deals with calibration, referencing, and normalization of isotope ratio data and provides practical hints for quality assurance in stable isotope laboratories. A large selection of illustrative applications of CSIA is given in Chapter 6. Following a short introduction to current challenges in the fields of authenticity control of food and beverages, forensics, archaeology, doping control, environmental sciences, and extraterrestrial matter, Bibliography Compound-specific stable isotope Analysis Maik A. Jochmann and Torsten C. Schmidt Royal Society of Chemistry ISBN: 978-1-84973-157-7 Hardcover, 250 pages December 2012, GBP55.99 T. B. Hofstetter (*) Environmental Chemistry, Eawag, UEberlandstrasse 133, 8600 Dubendorf, Switzerland e-mail: Thomas.Hofstetter@eawag.ch Anal Bioanal Chem (2013) 405:2753-2754 DOI 10.1007/s00216-013-6729-0 the authors illustrate the important contributions that isotopic analysis in individual compounds can make. The book ends with a summary of ongoing analytical developments. Each chapter is accompanied with an extensive list of references and a selection of links to electronic illustrative materials. Comparison with existing literature This book is dedicated to analytical approaches to isotope ratio measurements and focuses almost exclusively on the isotopic analyses in individual compounds after their chromatographic separation. With this strategy, the authors follow an alternative path to stable isotope analysis and research. Many other monographs in the field deal with isotopes and isotopically substituted molecules in the context of a scientific discipline or field of application, for example, in chemistry (Wolfsberg et al., Isotope Effects in Chemical, Geological, and Bio Sciences 2010), ecology (Dawson & Siegwolf (Eds.), Stable Isotopes as Indicators of Ecological Change 2007), and forensics (Meier- Augenstein, Stable Isotope Forensics 2010) to name just a few. In this context, instrumental aspects of isotope analyses are usually of minor concern or not focussed on CSIA. The latter is covered in detail in handbooks (e.g., de Groot (Ed.), Handbook of stable isotope analytical techniques 2004/2009) and review articles. This part of the scientific literature typically addresses the specific questions of experts rather than those of novices, which need a step-by-step introduction. Critical assessment The strong emphasis on practical aspects of CSIA together with their systematic presentation makes this book a highly welcome resource for CSIApractitioners. Thanks to the detailed description of typical instrumentation, its correct operation, and possible pitfalls, the information in this book covers all the important points for successful isotope ratio determination. Stable isotope lab managers will be able to review their procedures based on the contents of chapters 3 to 5. Newcomers, in contrast, can find a coherent introduction to a sophisticated piece of instrumentation together with a consistent presentation of the basic terminology. The more fundamental knowledge is shown together with practical recommendations, which is particularly valuable for non-expert readers. The illustrative topics and applications of Chapter 6 are well-suited to make a case for stable isotope analysis and an excellent motivation for future contributors to CSIA. This part of the book can also provide guidance to lecturers in search of suitable examples for their stable isotope classes. Summary and readership recommendation Compoundspecific Stable Isotope Analysis is presumably the first book to make this advanced technique accessible to a broader audience. The book is an excellent support for isotoperelated laboratory courses on MSc and PhD student level, where it will be used for practical advise as well as for background reading. Experienced researchers and science consultants will appreciate having this book on their shelves as a quick reference to a versatile and developing analytical technique. -- Thomas B.

Hofstetter * Anal Bioanal Chem 2013 Vol 405 2753 * Reseña del editor The use of Compound-specific Stable Isotope Analysis (CSIA) is increasing in many areas of science and technology for source allocation, authentication, and characterization of transformation reactions. Until now, there have been no textbooks available for students with an analytical chemical background or basic introductory books emphasising the instrumentation and theory. This book is the first to focus solely on stable isotope analysis of individual compounds in sometimes complex mixtures. It acts as both a lecture companion for students and a consultant for advanced scientists in fields including forensic and environmental science. The book starts with a brief history of the field before going on to explain stable isotopes from scratch. The different ways to express isotope abundances are introduced together with isotope effects and isotopic fractionation. A detailed account of the required technical equipment and general procedures for CSIA is provided. This includes sections on derivatization and the use of microextraction techniques in GC-IRMS. The very important topic of referencing and calibration in CSIA is clearly described. This differs from approaches used in quantitative analysis and is often difficult for the newcomer to comprehend. Examples of successful applications of CSIA in food authenticity, forensics, archaeology, doping control, environmental science, and extraterrestrial materials are included. Applications in isotope data treatment and presentation are also discussed and emphasis is placed on the general conclusions that can be drawn from the uses of CSIA. Further instrumental developments in the field are highlighted and selected experiments are introduced that may act as a basis for a short practical course at graduate level.
