Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia is a complete and authoritative reference work for this rapidly evolving field. Over 200 international scientists, each experts in their specialties, have written over 330 separate topics on different aspects of geochemistry including geochemical thermodynamics and kinetics, isotope and organic geochemistry, meteorites and cosmochemistry, the carbon cycle and climate, trace elements, geochemistry of high and low temperature processes, and ore deposition, to name just a few. The geochemical behavior of the elements is described as is the state of the art in analytical geochemistry. Each topic incorporates cross-referencing to related articles, and also has its own reference list to lead the reader to the essential articles within the published literature. The entries are arranged alphabetically, for easy access, and the subject and citation indices are comprehensive and extensive. Geochemistry applies chemical techniques and approaches to understanding the Earth and how it works. It touches upon almost every aspect of earth science, ranging from applied topics such as the search for energy and mineral resources, environmental pollution, and climate change to more basic questions such as the Earth’s origin and composition, the origin and evolution of life, rock weathering and metamorphism, and the pattern of ocean and mantle circulation. Geochemistry allows us to assign absolute ages to events in Earth’s history, to trace the flow of ocean water both now and in the past, trace sediments into subduction zones and arc volcanoes, and trace petroleum to its source rock and ultimately the environment in which it formed. The earliest of evidence of life is chemical and isotopic traces, not fossils, preserved in rocks. Geochemistry has allowed us to unravel the history of the ice ages and thereby deduce their cause. Geochemistry allows us to determine the swings in Earth’s surface temperatures during the ice ages, determine the temperatures and pressures at which rocks have been metamorphosed, and the rates at which ancient magma chambers cooled and crystallized. The field has grown rapidly more sophisticated, in both analytical techniques that can determine elemental concentrations or isotope ratios with exquisite precision and in computational modeling on scales ranging from atomic to planetary.

This book was released on 2013-11-11 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: During recent years there has been increasing interest in the value of a number of chemical and physical-chemical analytical methods for the detection and characterization of microorganisms. Furthermore, such methods are currently used in studies on microbial metabolic processes, on the role of microorganisms in the turnover of inorganic and organic compounds, and on the impact on environmental changes by microbial activity. Moreover, the introduction of some of these methods not only shortens the analytical time period compared to ·'traditional" techniques, but also improves the analytical quality. Mass spectrometry (MS) combined with chromatographic inlet systems, particularly gas chromatography (GC), belongs to those methods which during recent years have established their value for the above-mentioned purposes. The present volume starts with basic chapters on the principles for MS and common inlet systems, particulary Gc. It discusses applications of these techniques to a number of microbiological disciplines, e.g., ecologi cal and medical microbiology. Emphasis is laid on organic compound classes vii viii / PREFACE of special relevance to microbiology, e.g., volatiles, lipids, amino acids, peptides and carbohydrates. Some compound classes of a more general biochemical rather than specific microbiological importance, e.g., steroids and nucleotides, are dealt with briefly. The editors wish to thank all those who have contributed to this book. We hope it will stimulate further research in this futuristic field and will be of practical value.

This book was released on 2020-02-25 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: All sub disciplines in Organic Geochemistry (Petroleum Geochemistry, Environmental Geochemistry etc.) are linked by the basic analytical approaches used for identification and quantitation of individual organic substances. Hence, a fundamental prerequisite for organic geochemists is the knowledge not only about the individual analytical techniques but more about their potential as well as their limitations. In this issues basic analytical procedures and techniques are introduced comprising fundamental steps like sampling and sample storage, aspects of sample treatment like extraction and fractionation procedures and finally the specific techniques used for organic analyses on partially very low concentration levels such as mass spectrometry or infrared spectroscopy. Beside the technical aspects also application on organic-geochemical problems and the standard data evaluation practice is introduced. Finally, special chapters point to analytical pitfalls and to principal standard operation procedures. The intention of this issue is to get the readers familiar with analytical Organic Geochemistry and to enable them to assess the quality and suitability of specific analytical approaches, in particular with respect to the organic-geochemical problems.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The utility of mass spectrometric (MS) techniques is highlighted in three studies that analyze a wide variety of organic compounds in complex environmental matrices. First, a battery of MS techniques is used to identify and quantify over 180 compounds emitted from crumb rubber amended synthetic turf. Quality control data demonstrate the efficacy of these MS techniques for the purpose intended. Second, high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) is used to measure very low levels of estrogenic and androgenic compounds in samples from Confined Animal Farming Operations (CAFOs). Fractionation HPLC is used to isolate hormonal bioactivity and to determine whether the toxicological potency, as measured by bioassay, can be accounted for by the types and concentrations of hormones identified. Third, HPLC-MS/MS is used with a variety of scan modes along with isotope labeling to propose abiotic breakdown pathways for the sulfonamide antimicrobial compound sulfamethazine. In the first study, most compounds were analyzed at the low ng/sample level with good accuracy and precision. However, compounds in laboratory air presented interference problems for some analytes, such as carbon disulfide, 2-methyl butane, acetone, benzene, methylene chloride, methanol, and pentane. HPLC-MS/MS methods replaced established gas chromatographic methods to measure seven N-Nitrosamines, benzothiazole, 2-mercaptobenzothiazole, 4-tert-octylphenol, butylated hydroxytoluene, and butylated hydroxyanisole. In the CAFO study, much of the hormonal bioactivity in the samples could be accounted for by the HPLC-MS/MS target compounds detected (17-beta-estradiol, 4-androstene-3,17-dione, progesterone, 17,20-dihydroxyprogesterone, nandrolone, and zearalenone). Gas Chromatography - Mass Spectrometry (GC/MS) analysis of bioactive fractions identified compounds potentially responsible for unaccountable endocrine disrupting bioactivity (a triazine herbicide and a phthalate). Finally, HPLC-MS/MS analysis showed that sulfamethazine is transformed by birnessite under oxic conditions to an azo-dimer self-coupling product and SO2 extrusion products. These studies demonstrate how modern MS techniques are effective for analyzing a wide array of organic compounds in difficult environmental matrices.

This book was released on 2011-05-17 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: A working definition of the discipline of chemical ecology might be "the study of the structure, function, origin, and significance of naturally occurring compounds that mediate inter-and intraspecific interactions between organisms. " In particular, chemical ecology focuses on determining the role of semiochemicals and related compounds in their natural contexts. Thus, chemical ecology is distinct from disciplines such as pharmacology, in which compounds are screened for uses outside their natural context, for example in the screening of natural products for use as drugs. Superficially, many of the methods used in the various branches of natural products chemistry, such as pharmacology and chemical ecology, are very similar, but each branch has developed its own set of specialized methods for dealing with the problems characteristic of that discipline. For example, in chemical ecology, many semiochemicals are isolated and identified using only a few micrograms or less of material. Although the same general chromatographic and spectroscopic techniques are used as would be used with the identification of most organic compounds, specialized techniques have been developed for handling these very small quantities, allowing the maximum amount of informa tion to be recovered from the minimum amount of sample. These micro scale techniques, and the problems unique to working with very small amounts of sample, are rarely covered in detail in reference books on the isolation and identification of biologically active natural chemicals.
