This book was released on 1974 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a study on the role of natural organics in determining the physical properties of soils, the use of combined gas chromatographic/mass spectrometric methods for identification of the more volatile organic chemicals in soils were explored. Soil was first treated at 100, 150, and 200C to select the optimum temperature where minimum pyrolysis of soil organic matter occurred. The vapors from three soils heated in a closed system at 150C were then analyzed. Subsequent refinement in technique involved collection of vapor from the three soils maintained at 150C using a constant flow sample holder/inlet system. About 50 organic compounds were identified. While application of this approach is restricted to the volatile compounds in the lower molecular weight range, conditions of analysis are thought to be suitable for identification of compounds originally present as opposed to pyrolysis products of soil organic matter.

Download or read book Aqueous Extraction Headspace Gas Chromatographic Meth Od for Determination of Volatile Organic Compounds in Soils written by and published by . This book was released on 1992 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study compares aqueous extraction-headspace/Gas Chromatography (GC) and the EPA SW-846 purge-and-trap-gas chromatography/mass spectrometry(Method 8240)for the determination of four common Volatile Organic Compounds (VOCs) in soils. Comparisons were made on two fortified soils and two contaminated field soils. In only two of the cases were consistent significant differences found-for the two most hydrophobic compounds in a high organic carbon soil, and for TCE in a field-contaminated soil that had previously shown slow aqueous VOC desorption. The findings strongly suggest that aqueous extraction-headspace/GC can be used not only to screen soils for VOCs giving same-day results, but often will provide results not significantly different from current laboratory based measurements.

Download or read book Introduction to Analytical Methods in Organic Geochemistry written by Jan Schwarzbauer and published by Springer Nature. 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.

Download or read book Encyclopedia of Geochemistry written by William M. White and published by Springer. This book was released on 2018-07-24 with total page 1680 pages. 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.
