Published by University Science Books, 20 Edgehill Rd., Mill Valley, CA 94941. The first edition was published more than 25 years ago, the third, in 1980. Automated computer-matching procedures are still only an aid to, not a replacement for, the skilled interpreter; and the path to that skill, as emphasized in every edition of this text, is practice.

Interpretation of Mass Spectra of Organic Compounds outlines the basic instrumentation, sample handling techniques, and procedures used in the interpretation of mass spectra of organic compounds. The fundamental concepts of ionization, fragmentation, and rearrangement of ions as found in mass spectra are covered in some detail, along with the rectangular array and interpretation maps. Computerization of mass spectral data is also discussed. This book consists of nine chapters and begins with a historical overview of mass spectrometry and a discussion on some important developments in the field, along with a summary of interpretation objectives and methods. The following chapters focus on instruments, ion sources, and detectors; recording of the mass spectrum and the instrumental and sample variables affecting the mass spectrum; sample introduction systems; and fragmentation reactions. Correlations as applied to interpretations are also considered, with emphasis on applications of the branching rule as well as beta-bond and alpha-bond cleavages. Example interpretations, calculations, data-processing procedures, and computer programs are included. This monograph is intended for organic chemists, biochemists, mass spectroscopists, technicians, managers, and others concerned with the whys and wherefores of mass spectrometry.

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

A multidisciplinary approach to understanding the fundamentals of mass spectrometry for bacterial analysis From chemotaxonomy to characterization of targeted proteins, Identification of Microorganisms by Mass Spectrometry provides an overview of both well-established and cutting-edge mass spectrometry techniques for identifying microorganisms. A vital tool for microbiologists, health professionals, and analytical chemists, the text is designed to help scientists select the most effective techniques for use in biomedical, biochemical, pharmaceutical, and bioterror defense applications. Since microbiological applications of mass spectrometry require a basic understanding of both microbiology and analytical chemistry, the editors have incorporated material from both disciplines so that readers from either field will come to understand the necessary principles of the other. Featuring contributions from some of the most recognized experts in both fields, this volume provides specific examples of fundamental methods as well as approaches developed in the last decade, including: * Metastable atom bombardment pyrolysis mass spectrometry * Matrix-assisted laser desorption/ionization mass spectrometry (MALDI) * MALDI time-of-flight mass spectrometry (MALDI-TOF MS) of intact bacteria * High-resolution Fourier transform mass spectrometry (FTMS) * Electrospray ionization (ESI) mass spectrometry Identification of Microorganisms by Mass Spectrometry represents the most comprehensive and up-to-date work on the topic currently available. It is liberally illustrated with figures and tables and covers every aspect of spectrometric identification of microorganisms, including experimental procedures, various means of sample preparation, data analysis, and interpretation of complex mass spectral data.

Introducing the principles, practice and applications of mass spectrometric techniques in the study of natural substances in foods, this book conveys the depth and breadth of modern mass spectrometry in relation to food analysis. It covers traditional techniques such as electron and chemical ionisation and newer soft ionisation techniques such as matrix-assisted laser desorption ionisation and electrospray. All of these techniques are especially relevant in food quality and safety studies and in biopolymer analysis. The ability to analyse biopolymers by mass spectrometry is having a major impact on the study of food structure components, food proteins, food pathogens and food components produced from genetically modified organisms. The principles and practice of mass spectrometry are covered in the early chapters and are followed by applications in flavour analysis and the determination of non-nutrient, biologically-active, natural substances in foods. The analysis and metabolic studies of amino acids, peptides, proteins, lipids, sugars, carbohydrates and vitamins is also discussed, with separate chapters on mineral and micronutrient metabolism and techniques of pyrolysis mass spectrometry. Mass Spectrometry of Natural Substances in Food will be a valuable resource for food scientists, food analysts and others working in food research, nutrition and safety.

This book describes the full range of techniques and applications used in mass spectrometry. Researchers in universities and industry laboratories use this versatile technique because of its ability to identify a minute amount of material quickly. The technique solves analytical problems in a huge variety of fields. The authors adopt an instructional approach and make use of recent examples to illustrate important points. This second edition includes new methods and applications that have developed in the past ten years. The authors discuss powerful methods combining mass spectrometry with newer separation techniques, the increased use of computers, and analysis of once difficult polar and large-mass compounds such as proteins using new ionization methods. The book, requiring no previous knowledge of mass spectrometry, is an ideal teaching text at both the undergraduate and postgraduate level, and will also be of considerable interest to research workers.
