A Handbook Of Derivatives For Mass Spectrometry

Chemical derivatisation of functional groups has proved popular since the beginning of organic mass spectrometry as a means to enhance the stability and volatility of the analytes as well as facilitating structure elucidation. This book provides comprehensive information on the wide range of derivatisation methods. Each chapter looks at a particular area of derivatisation and includes extensive references to the literature for further research where necessary. There are nearly 1800 references, which, as well as full bibliographic information, include chapter/paper titles where appropriate and Digital Object Identifiers (DOIs) to allow easy retrieval of the online version of the referenced publication. The emergence of atmospheric pressure ionisation and other soft ionisation techniques has not diminished the interest in such chemical techniques, as witnessed by the many chemical tags used in quantitative proteomics (Chapter 9). The last two chapters, a substantial part of the book, deal with derivatisation for use with soft ionisation of both small and large molecules. Chapters Silylation Acylation Alkylation (Arylation) Cyclic derivatives Monofunctional compounds Polyfunctional compounds On-line derivatisation/degradation Soft ionisation—small molecules Soft ionisation—large molecules

A practical handbook of derivatives and an invaluable reference source for chemists using chromatography for derivatization. Since publication of the first edition in 1977, there have been many developments in chemical derivatization which have gone hand-in-hand with advances in chromatography. This handbook will be of use not only in core chemistry but also in food analysis, clinical and biochemical analysis, toxicological, environmental and forensic testing and refining.

Brings together practical information previously available only innumerous separate sources. Handbook of Analytical DerivationReactions begins with an overview of analytical derivatizationwith a section on apparatus. Describes analytical derivatizationmethods organized according to the sample to be derivatized.Discussion of methods includes derivative type, reagent, sampletype, reaction, and typical procedure with comments and referencesfor each.

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

Due to its enormous sensitivity and ease of use, mass spectrometry has grown into the analytical tool of choice in most industries and areas of research. This unique reference provides an extensive library of methods used in mass spectrometry, covering applications of mass spectrometry in fields as diverse as drug discovery, environmental science, forensic science, clinical analysis, polymers, oil composition, doping, cellular research, semiconductor, ceramics, metals and alloys, and homeland security. The book provides the reader with a protocol for the technique described (including sampling methods) and explains why to use a particular method and not others. Essential for MS specialists working in industrial, environmental, and clinical fields.

Mass spectrometry has undergone a great deal of development as an empirical subject and many useful approaches to the analysis and identification of organic molecules have been developed without a detailed understanding of theory of ion behaviour. This is also the way in which the subject is usually approached and it is the tack adopted here. That does not mean to say that an understanding of ion behaviour is not important - it is, but that understanding is still being developed and this book is designed for those wishing to use mass spectrometry now.

The only comprehensive guide to CIMS applications in structural elucidation and analytical studies Chemical Ionization Mass Spectrometry, 2nd Edition, provides a comprehensive, up-to-date review of CIMS applications in structural elucidation and quantitative analytical studies. For the benefit of readers without a background in gaseous ion chemistry, a thorough review is presented in Chapter 2. Other chapters discuss such topics as reagent ion systems within the context of the thermochemistry and kinetics of the ionization process, including reactions and the type of information obtained; isotopic exchange reactions; stereochemical effects in chemical ionization; and reactive ion/molecule collisions in quadrupole cells. Chemical ionization mass spectra of 13 classes of compounds are discussed in detail to illustrate the influence of different functional groups on the spectra observed. Chemical Ionization Mass Spectrometry, 2nd Edition will be a valuable reference for anyone interested in mass spectrometry and gaseous ion chemistry in general.

This is the first modern book to treat inorganic and organometallic mass spectrometry simultaneously. It is textbook and handbook in one; as a textbook it introduces the techniques and gives hints on how to apply the various techniques, as a handbook it lists all available ionization techniques for just about any given compound. The book also includes non-mathematical explanations of how modern MS instruments work Mass Spectrometry of Inorganic and Organometallic Compounds will inspire the synthetic inorganic and organometallic chemist with the confidence to apply some of the new techniques to their characterization problems.
