Introduction to Analytical Methods in Organic Geochemistry

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.
