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.

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.

Gas chromatography remains the world's most widely used analytical technique, yet the expertise of a large proportion of chromatographers lies in other fields. Many users have little real knowledge of the variablesin the chromatographic process, the interaction between those variables, how they are best controlled, how the quality of their analytical results could be improved, and how analysis times can be shortened to facilitate the generation of a greater numberof more reliable results on the same equipment. An analyst with a more comprehensive understanding of chromatographic principles and practice, however, can often improve the quality of the data generated, reduce the analytical time, and forestall the needto purchase an additional chromatograph or another mass spectrometer.The Second Edition of Analytical Gas Chromatography is extensively revised with selected areas expanded and many new explanations and figures. The section on sample injection has been updated to include newer concepts of split, splitless, hot and cold on-column, programmed temperature vaporization, and large volume injections. Coverage of stationary phases now includes discussion, applications, and rationale of the increased thermal and oxidative resistance of the newly designed silarylenepolysiloxane polymers. Conventional and"extended range"polyethylene glycol stationary phases are examined from the viewpoints of temperature range and retention index reliabilities, and the chapter on"Variables"has been completely rewritten. The ways in which carrier gas velocity influences chromatographic performance is considered in detail, and includes what may be the first rational explanation of the seemingly anomalous effects that temperature exercises on gas viscosity (and gas flow). The practical effects that these changes cause to the chromatography is examined in pressure-, flow-, and"EPC-"regulated systems."Column Selection, Installation, and Use"has been completely rewritten as well. The accuracy of theVan Deemter plots has been greatly enhanced; a new program corrects for the first time for the changes in gas density and diffusion that occur during the chromatographic process because of solute progression through the pressure drop of the column. A new section has also been added on meeting thespecial requirements of columns destined for mass spectral analysis. The chapter on"Special Applications"has been expanded to include considerations of"selectivity tuning,"of fast analysis, and the section of Applications has been thoroughly updated and expanded. Incorporates nearly 60% new material Covers the newest concepts and materials for sample injection and stationary phases Presents detailed consideration of the influence of carrier gas velocity on practical aspects of chromatographic performance Contains a chapter on "Special Analytical Techniques" which includes consideration of selectivity tuning and fast analysis Provides a new section addressing the special requirements of columns to be used in mass spectral analysis Includes an improved program that greatly enhances the accuracy of the Van Deemter plots by more accurately depicting localized chromatographic conditions at each point in the column
