Mass spectrometry has played an integral part in the study of organic molecular structures for more than 50 years, offering significant information from small amounts of sample. The mass spectrum produced by electron impact ionization presents a pattern of peaks that can often give definitive structural information about an unknown compound. Introductory Mass Spectrometry, Second Edition guides readers in the understanding and recognition of those patterns, discussing mass spectra in terms that are familiar to chemists. It provides a basis for chemists to interpret mass spectra to solve particular structural problems. The Second Edition has been updated with modern techniques and data handling. Beginning with an introduction to the principles and instrumentation, it then sequentially explains the processes that occur in the mass spectrometer following ionization. The book is unique in the large number of mass spectra presented and provides examples of mass spectra from a wide variety of organic chemicals, concentrating on the relationships between fragmentation patterns, common chemical reactions, and chemical structures. The book also discusses mass spectra obtained with softer ionization techniques, which provide definitive information regarding molecular weights. The text describes mass spectra produced by electron ionization, discussing how the spectral peak pattern relates to molecular structure. It details the use of high-resolution and accurate mass measurement to determine elemental composition of ions in order to identify unknown substances. The book also introduces some of the recent techniques that can be employed to extend the usefulness of mass spectrometry to high molecular weight substances and more polar substances. It includes examples and problems representing a cross section of organic chemistry to help readers integrate the principles presented.

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.

Mit Massenspektrometrie – ein Lehrbuch liegt ein Werk vor, das mit seiner umfassenden, präzisen Darstellung sowie seinen vielen gelungenen Illustrationen und Fotos eine Lücke auf dem deutschsprachigen Markt schließt. Dieses im englischsprachigen Raum bereits gut etablierte Buch führt auf grundlegende Weise an die Massenspektrometrie heran, indem es die Prinzipien, Methoden und Anwendungen logisch aufeinander aufbauend erklärt. Schritt für Schritt lernt der Leser, was diese analytische Methode leisten kann, auf welch vielfältige Art Massenspektrometer isolierte Ionen in der Gasphase erzeugen, selektieren und manipulieren können und wie man aus den resultierenden Massenspektren analytische Information gewinnt. Moderne sanfte Ionisationsmethoden wie ESI, APCI oder MALDI, klassische Verfahren wie EI, CI, FAB oder FD, Oberflächentechniken wie DESI oder DART und elementmassenspektrometrische Verfahren werden didaktisch durchdacht behandelt. Studienanfänger werden von dem Werk ebenso profitieren wie Fortgeschrittene und Praktiker. Ergänzend zum Buch betreibt der Autor eine frei zugängliche (englischsprachige) Internetseite mit zahlreichen Übungsaufgaben, Lösungen und Bonus-Material unter http://www.ms-textbook.com

Trace Environmental Quantitative Analysis: Principles, Techniques, and Applications, Second Edition offers clear and relevant explanations of the principles and practice of selected analytical instrumentation involved in trace environmental quantitative analysis (TEQA). The author updates each chapter to reflect the latest improvements in TEQA that have resulted in greater levels of sensitivity. The book begins with an overview of regulatory and EPA methods, followed by quantitative data reduction and interpretation of analytical results, sample preparation, and analytical instrumentation. Among the more than two-dozen new topics are the underlying principles of GC-MS, GC-MS-MS, LC-MS, and ICP-MS, column chromatographic cleanup, gel permeation chromatography, applications to biological sample matrices, and matrix solid-phase dispersion. The chapter on sample preparation now includes more alternatives to liquid-liquid extraction, highlighting Solid Phase Microextraction (SPME), and Stir Bar Sorptive Extraction (SBSE). The final chapter contains laboratory-tested experiments to practice the techniques appearing in the text. Appendices include a convenient glossary, applications to drinking water, computer programs for TEQA, instrument designs, and useful Internet links for practicing environmental analytical chemists. Featuring personal insight into the theory and practice of trace analysis from a bench analytical chemist, the second edition of Trace Environmental Quantitative Analysis takes readers from the fundamental principles to state-of-the-art methods of TEQA currently used in leading laboratories.

An updated and unified approach to mass spectral interpretation, emphasizing the application of basic principles Electron ionization (EI) mass spectrometry-an analytical tool used by chemists to identify and quantify compounds in a complex mixture-remains an essential technique for measuring low-molecular weight compounds such as drugs, flavor and odor components, pesticides, and petroleum products. The interpretation of EI mass spectra also remains an important skill because attempts to identify compounds using computer databases do not always yield useful results. Understanding Mass Spectra: A Basic Approach, Second Edition presents the introductory-level student with the fundamental concepts of mass spectrometry, providing a useful foundation for solving basic problems in a laboratory setting. Completely revised, the Second Edition includes: A detailed overview of theory and instrumentation Step-by-step descriptions of interpretative strategies Many fascinating real-world case studies and examples Additional skill-building problems with clearly explained answers Easy-to-follow explanations of all important mathematical derivations Convenient lists and tables of information needed to identify unknowns Additional suggested readings Containing problems and examples with a wide range of complexity, Understanding Mass Spectra emphasizes simple, practical treatments of topics such as fragmentation types and underlying mathematical relationships. Mastering these treatments allows for a solid grounding in basic principles and encourages advanced investigation. With this emphasis on comprehension, Understanding Mass Spectra, Second Edition provides a vital introduction to the field for upper-level undergraduates and beginning graduates, as well as a valuable resource for professional chemists working in analytical laboratories.
