Available in PDF, EPUB and Kindle. Book excerpt: Clear, comprehensive, and state of the art, the groundbreaking book on the emerging technology of direct analysis in real time mass spectrometry Written by a noted expert in the field, Direct Analysis in Real Time Mass Spectrometry offers a review of the background and the most recent developments in DART-MS. Invented in 2005, DART-MS offers a wide range of applications for solving numerous analytical problems in various environments, including food science, forensics, and clinical analysis. The text presents an introduction to the history of the technology and includes information on the theoretical background, for exampleon the ionization mechanism. Chapters on sampling and coupling to different types of mass spectrometers are followed by a comprehensive discussion of a broad range of applications. Unlike most other ionization methods, DART does not require laborious sample preparation, as ionization takes place directly on the sample surface. This makes the technique especially attractive for applications in forensics and food science. Comprehensive in scope, this vital text: -Sets the standard on an important and emerging ionization technique -Thoroughly discusses all the relevant aspects from instrumentation to applications -Helps in solving numerous analytical problems in various applications, for example food science, forensics, environmental and clinical analysis -Covers mechanisms, coupling to mass spectrometers, and includes information on challenges and disadvantages of the technique Academics, analytical chemists, pharmaceutical chemists, clinical chemists, forensic scientists, and others will find this illuminating text a must-have resource for understanding the most recent developments in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Trace Analysis by Mass Spectrometry deals with trace analysis of solids and liquids by mass spectrometric techniques. Topics include the physics and techniques of electrical discharge ion sources, transmission of ions through double focusing mass spectrometers, and detection and measurement of ions by ion-sensitive plates. The ion sources used are principally electrical discharge type sources. This book is comprised of 14 chapters. The first several chapters focus on the basic physics of electrical discharge ion sources, double focusing mass spectrometry, and the measurement of arrays of mass resolved ion beams by electrical detection methods and with ion sensitive emulsions. The discussion then shifts to the problem of obtaining the chemical composition of the recorded mass resolved ion sample and relating this composition to that of the original sample. The chapters that follow describe specific techniques for analyzing special samples such as insulators, powders, microsamples, biological materials, reactive and low melting point substances, radioactive materials, and gases in solids. The remaining chapters include the use of laser ion sources in the analysis of solids and the analysis of surfaces particularly with sputter ion sources. This book will be of interest to students and practitioners of physics and chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometry is an analytical technique that can be used for the structural characterization and quantification of a wide range of molecules. The technique is extensively used by chemists for the analysis of small and volatile organic compounds. Mass spectrometry has long been an important technique for the identification of materials ranging from pure compounds to complex mixtures. Mass spectrometry can be used to determine molecular weight of compounds or using different ionization conditions, can provide more structural details through the analysis of fragmentation patterns. This level of detail can be attained for pure compounds and some mixtures. Mass spectrometry can also be combined with separation techniques such as gas chromatography or liquid chromatography to allow more complex mixtures to be examined. These hyphenated techniques provide a range of options for the characterization of complex materials.

This book was released on 1973 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volatiles trapped in rocks can be released either by heating or by crushing. Unfortunately crushing generates new, clean surfaces which adsorb chemically active gases and thus change both the amount and composition of the evolved gases. For quantitative analysis the volatiles were released by heating 0.1-g samples in fused silica tubes at temperatures up to 1200°C. The evolved volatiles were separated into two fractions by fractional freezing. Volatiles which were not condensed in a liquid nitrogen-cooled trap (hydrogen, carbon monoxide, methane, nitrogen, helium, etc.) were mixed with a known amount of argon internal standard and leaked into a calibrated E.A.I. QUAD 1110 mass spectrometer for analysis. The condensable volatiles (water, carbon dioxide, higher hydrocarbons) were subsequently evaporated and analyzed in the same way. The analog output from the mass spectrometer was fed to a digital integrator which printed the areas of the peaks on a teletype and simultaneously punched a paper tape. The tape was later transmitted over a telephone line to a time-shared computer for data processing.

Book excerpt: A basic overview of mass spectrometry relevant to life and health science applications, illustrated throughout with relevant case studies This introductory text provides information and assistance to new users of mass spectrometry (MS) working in clinical or biochemical fields who are faced with implementing and designing quantitative mass spectrometric assays for a variety of classes of molecules of biological interest. It presents a detailed discussion on how to optimize measurement parameters for a candidate reference quantitative analysis, including calibration procedures, sensitivity, reproducibility, speed of assay and compliance with regulatory authorities. Quantitative Biological and Clinical Mass Spectrometry uses examples where development has not been immediately successful but where unforeseen problems have arisen and describes the strategies used to solve these. Advances in addressing the very large numbers of clinical samples that arise on routine screening programs such as those involved in inborn errors of metabolism studies are discussed. Direct mass spectrometric based analyses applicable to point of care testing (POCT) situations are also covered. The book concludes with a short section on possible novel developments, bibliography, references, and a glossary of terms. Shows how the presence of false results can be detected and understood Describes the ‘parts’ of modern instruments from sample introduction through ionization, mass analysis and detection, and the variety of techniques of tandem mass spectrometry Discusses the requirement for specificity in an assay method Fully illustrated throughout Highly relevant to all key areas of mass spectrometric analysis Quantitative Biological and Clinical Mass Spectrometry appeals to those newly exposed to the use of combined chromatography and mass spectrometry for analysis of biological material and to scientists experienced in automated clinical analysis using immunoassays or who are new to mass spectrometry.

Book excerpt: Physical Chemistry, A Series of Monographs: Active Nitrogen presents the methods by which active nitrogen may be produced. This book is composed of five chapters that evaluate the energy content, molecular spectrum, and the emission of active nitrogen. Some of the topics covered in the book are the summary of light-emitting systems of active nitrogen; analysis of Long-Lived Lewis-Rayleigh Afterglow theory and Ionic theory of Mitra; reactions followed by induced light emission; and characteristics of homogeneous recombination. Other chapters deal with the analysis of metastable molecule theories and the mechanisms for reactions of active nitrogen involving direct N(4S) attack. The discussion then shifts to the rate constants for reactions induced by direct N(4S) attack. The evaluation of the Short-Lived Energetic Afterglow theory is presented. The final chapter is devoted to the examination of emission from molecular species with electronic energy levels below 9.76 eV. The book can provide useful information to physicists, students, and researchers.
