This book was released on 2012-12-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of supercritical fluids in analytical chemistry is still grow ing. More and more analysts are discovering the favorable advan tages for a number of applications. Especially supercritical fluid extraction (SFE) has attracted a lot of interest in recent years due to its simplicity. Supercritical fluid chromatography (SFC) has become better established and the development of this technique has been accelerated by the many applications with capillary col umns which have been published in the literature. At first SFC equipment was based on instruments commonly used for liquid chromatography, and the first commercial in struments were derived from this technology. However, capillary columns can be much more easily interfaced to gas chromatogra phy equipment especially to the detectors commonly used for Oc. Many stationary phases both for packed micro columns and capillary columns have been designed for SFC purposes extending this technology to LC and OC. The most common fluid applied in SFC and SFE is carbon dioxide. The advantages of supercritical CO , such as having dif 2 fusivity like a gas and solvating power depending on temperature and pressure, are also valid for other fluids and modified fluids. Both properties are valuable for sample extraction and extraction selectivity.
Book Synopsis Supercritical Fluids in Chromatography and Extraction by : R. M. Smith
Download or read book Supercritical Fluids in Chromatography and Extraction written by R. M. Smith and published by Elsevier Science Limited. This book was released on 1997 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the mid 1980s supercritical fluid chromatography (SFC) arose with considerable fanfare as the new technique which would shortly "displace HPLC" and become the "universal separation method". After the initial hype had passed, there has still remained a significant group of applications in both chromatography and extraction for which supercritical fluids are the most suitable solvents. These form the basis of this volume, which illustrates the present state of analytical supercritical technology by a collection of review and research papers. Many publications in this field have blurred the boundaries of supercritical fluids, claiming that they filled a gap between gases and liquids and "had the properties of both". This was never true and this book seeks a more rational view of the state of application of supercritical fluids as their position in the analytical laboratory becomes clearer. These papers emphasise that future chromatographers should not be compartmentalised into "gas chromatographers" or "liquid chromatographers" but should view the field as a series of merging separation techniques. The overall emphasis is on extraction methods, usually as a sample preparation method prior to HPLC or GC analysis, but in some cases the extract is examined directly as the analytical step. This bias on extraction methods reflects the impact of supercritical fluids in the working laboratory. It is therefore an area where advances can have the maximum benefit for the user. The papers on chromatography are diverse and adventurous, covering particularly chiral chromatography and metal complex analysis, where SFC offers particular advantages over existing methods. Rather than be a separate branch of chromatography or extractions it is clear that the use of solvents above their normal conditions of temperature and pressure, up to and including the supercritical state, will continue to expand the range of analytical methods as part of an overall spectrum of solubility, polarity and volatility properties of solvents and mobile phases. This volume is an important addition to this movement and will help to redress the lack of education in the theory and practice of sample preparation which has been a great limiting factor for SFC and SFE.

The book also includes highlights of modern applications of SFC in the final chapters—namely pharmaceuticals, consumer products, foods, polymers, petroleum-related mixtures, and cannabis—and discusses the future of SFC. Provides a clear explanation of the physical and chemical properties of supercritical fluids, which gives the reader a better understanding of the basis for improved performance in SFC compared to HPLC and GC Describes the advantages of SFC as a green alternative to HPLC and GC for the analysis of both polar, water-soluble, and non-polar analytes Details both achiral and chiral SFC method development, including modifiers, additives, the impact of temperature and pressure, and stationary phase choices Details why SFC is the premier modern preparative chromatographic technique used to purify components of mixtures for subsequent uses, both from performance and economic perspectives Covers numerous detectors, with an emphasis on SFC-MS, SFC-UV, and SFC-ELSD (evaporative light scattering detection) Describes the application of SFC to numerous high-value application areas Modern Supercritical Fluid Chromatography: Carbon Dioxide Containing Mobile Phases will be of great interest to professionals, students, and professors involved in analytical, bioanalytical, separations science, medicinal, petroleum, and environmental chemistries.
