Available in PDF, EPUB and Kindle. Book excerpt: Few fields have advanced faster over the past quinquennium than separation and estimation of steroids by the technique of gas phase chromatography. A detailed and complete review of this topic would therefore be beyond the scope of the authors contributing to this monograph. It was, however, felt that a discussion of some of the highlights of this rapid advance might be of help for laboratories estimating steroids in biological samples. One of the difficulties in producing a monograph of this kind is that before it can appear in print it is likely that some of the methods it discusses will have been overtaken by better methods, so swiftly is progress now made. No editorial power has been exercised in trying to make a uni form account of technology in this field, and the idiosyncrasies of each individual author have been left intact. Through this approach we hope that what has been lost in scholarly appearance is regained in general appeal.

This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade we have witnessed a revolution in analytical methods. The development of vapor phase chromatography for the separation and analysis of classes of substances ranging from metals and gases to a wide variety of organic materials has been one of the most exciting of these new techniques. Gas-liquid chromatography for the measurement of steroids is particularly significant for endocrinologists and reports during the past several years have demonstrated its usefulness. Because of the growing interest in this method, a committee of the Endocrinology Study Section composed of Drs. R. M. Dodson, Seymour Lieberman, Hilton A. Salhanick, and Ralph E. Peterson, felt that the time was propitious to hold this Workshop and it is on their behalf that I welcome you. We hope to obtain enough data during these sessions so that those attending this conference and those who may read the proceedings will be able to make an informed judgement about the usefulness of gas-liquid chromatography for the analysis of steroids in biological fluids. Thus, I hope that there will be adequate documentation of the reliability of the methods as well as a comparison of the advantages and disadvantages of this analytical method with other classical methods. If we can do this, this Workshop will provide a significant base of practical considerations about gas chromatographic analytic techniques. I would like to thank Drs. T. F. Gallagher, H. Wilson, H. Salhanick and L. Engel for agreeing to serve as Chairmen of the sessions.

Download or read book Practical Gas Chromatography written by Katja Dettmer-Wilde and published by Springer. This book was released on 2014-11-05 with total page 904 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas chromatography continues to be one of the most widely used analytical techniques, since its applications today expand into fields such as biomarker research or metabolomics. This new practical textbook enables the reader to make full use of gas chromatography. Essential fundamentals and their implications for the practical work at the instrument are provided, as well as details on the instrumentation such as inlet systems, columns and detectors. Specialized techniques from all aspects of GC are introduced ranging from sample preparation, solvent-free injection techniques, and pyrolysis GC, to separation including fast GC and comprehensive GCxGC and finally detection, such as GC-MS and element-specific detection. Various fields of application such as enantiomer, food, flavor and fragrance analysis, physicochemical measurements, forensic toxicology, and clinical analysis are discussed as well as cutting-edge application in metabolomics is covered.

Available in PDF, EPUB and Kindle. Book excerpt: The book represents the most complete description of the scientific results obtained on a photochemical experiment described 110 years ago by the Italian scientist Emanuele Paternò. This detailed that the photochemical reaction between a carbonyl compound and an alkene gives a corresponding oxetane. This oxetane ring is present in several naturally occurring compounds and bioactive compounds, and can be obtained with high regio- and stereoselectivity.

Download or read book Modern Methods of Steroid Analysis written by Erich Heftmann and published by Elsevier. This book was released on 2012-12-02 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods of Steroid Analysis reviews modern methods of steroid analysis such as liquid column chromatography, mass spectrometry, and gas chromatography. Topics covered include qualitative and quantitative analysis of plant sterols by gas-liquid chromatography; Raman spectroscopy of steroids; nuclear magnetic resonance; and applications of lanthanide shift reagents. A computerized method for rapid comparison and retrieval of infrared spectral data is also described. This volume is comprised of 22 chapters and begins with an analysis of hormonal steroids using liquid column chromatography, followed by a discussion on the separation of insect molting hormones using high-pressure liquid chromatography. The reader is methodically introduced to the application of gradient elution and thin-layer chromatography to the analysis of corticosteroids and 17-ketosteroids, as well as some aspects of mass spectrometry in steroid analysis. Subsequent chapters explore other methods such as optical rotatory dispersion and circular dichroism, along with radioisotope techniques. In particular, the radioimmunoassay of plasma steroid hormones and plasma aldosterone is considered. This book should be of interest to biochemists.
