Download or read book Analytical Gas Chromatography written by Walter Jennings and published by Elsevier. This book was released on 2012-12-02 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical Gas Chromatography is a free-standing introduction to and guide through the rapidly progressing field of analytical gas chromatography. The book is divided into 10 chapters that cover various aspects of analytical gas chromatography, from most advantageous column type to troubleshooting. The opening chapters of the book discuss the advantages of the open tubular column over the packed column. This topic is followed by significant chapters on various variables in the gas chromatographic process, including sample injection, stationary phase, carrier gas, and installation. The effect of changes in these variables on the solution elution order is also considered. A chapter also examines the influence of instrumental design features, such as excessive or unswept volumes in the flow path; suitability of the detection mode; and speed and fidelity of the data-handling equipment. The book also presents selected methods that have been employed to achieve better results for a given gas chromatographic problem. The application areas of gas chromatographic process, including food, flavor, fragrance, petroleum- and chemical-related, environment, biology, and medicine, are also presented. The concluding chapter addresses the basic troubleshooting knowledge and considers other chromatographic problems and methods for their rectification.

Download or read book Gas Chromatography of Organometallic Compounds written by T. R. Crompton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction into the armoury of the analytical chemist approximately two decades ago the technique of gas chroma tography has found very extensive applications in the analysis of most types of organic compounds. One of the few remaining limitations of the technique when applied to such compounds, namely the analysis of very highly boiling and or thermally unstable substances, has been overcome in many instances by the introduction of techniques such as silation for the conversion of sample components to lower boiling or more stable substances which can be gas chromatographed at reasonably low temperatures. All of this has been extensively dealt with in many books published during recent years dealing with the theory and practice of applying gas chromatography to the analysis and preparative separation of organic compounds. In parallel with these developments there has occurred, particu larly over the past decade, a growing interest in the application of gas chromatography to the analysis of organometallic compounds. Indeed, for many types of organometallic compounds, gas chromatography is the analytical method of choice particularly, as so often happens, when the sample is a mixture. To the author's knowledge no complete review exists of the published work in this very interesting new field; a situation it is hoped the present volume will rectify.

Download or read book Gas Chromatography Mass Spectrometry with Cold EI Leading the Way to the Future of GC MS written by Aviv Amirav and published by Scientific Research Publishing, Inc. USA. This book was released on 2021-08-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas chromatography-mass spectrometry (GC-MS) with supersonic molecular beams (SMB) (also named GC-MS with Cold EI) is based on GC and MS interface with a SMB and on the electron ionization (EI) of vibrationally cold analytes in the SMB (hence the name Cold EI) in a contact-free fly-through ion source. Cold EI improves all the central GC-MS performance aspects and brings a broad range of important benefits thereby leading the way to the future of GC-MS. Cold EI provides enhanced molecular ions combined with effective library-basedsample identification. Sample identification is further improved by the use of powerful TAMI software that is based on isotope abundance analysis and improved quadrupole mass accuracy for the provision of the sample elemental formula from its molecular ion group of isotopologues.

Download or read book Selective Detection for Gas Chromatography by Ultraviolet Spectrometry written by Debra L. Van Engelen and published by . This book was released on 1986 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectrometric detection systems for gas chromatography (GC) based on gas phase ultraviolet absorbance and fluorescence measurements have been developed and evaluated in this research. Polynuclear aromatic compounds (PNAs) are selectively detected by these systems. Limits of detection for PNAs range from 4 ng to 90 ng for absorbance determinations, and from 3 ng to 400 ng for fluorescence determinations made at a fixed waveband. The spacial design and optical components have been carefully selected to be compatible with hightemperature gas-phase measurements (ca. 250°C) while preserving the resolution of the chromatographic separation and enhancing the sensitivity of the multimode spectrometric determinations. Vapor-phase determinations of GC eluates are made directly as they leave the GC column in specially designed, heated flow-through detector cells with low volume and dead space. A long pathlength cell of 167 mm was used to enhance the sensitivity of the absorbance measurements. High-temperature, quartz fiber optic bundles transmit light to and from the detector cell, thus thermally isolating optical components. There are two configurations for these GC detection systems, each advantageous for either quantitative or qualitative determinations, respectively. In the first, waveband selection is accomplished via optical filters. These simple and compact systems are particularly suited to precise and sensitive determinations of polynuclear aromatic compounds. The sensitivity and selectivity of the absorbance and fluorescence measurements vary with individual compounds. These differences also provide some qualitative information about eluates. The second detection system configuration provides repetitive UV spectral information of GC eluates. This computer-controlled system scans a modified Czerny- Turner monochromator and can acquire up to two 62-nm spectra of eluates per second. Spectral information thus obtained may be used for identification purposes and to locate unresolved GC eluates. After compounds have been separated and identified, fixed waveband spectrometric data acquired at an absorption maximum may be used to determine concentrations.
