This book was released on 1985 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbine engine fuels are complex mixtures of hydrocarbons which have until recently, been obtained almost exclusively from petroleum. There is growing interest in developing alternative feedstocks for the eventual production of high-quality turbine engine fuels. The major analytical technique for separating the chemical constituents and analyzing fuels and synfuel feedstocks is high-resolution gas chromatography (HRGC), and the extreme chemical complexity of these hydrocarbon mixtures continues to challenge even the most sophisticated HRGC techniques. Therefore, the principal objective of this research was to identify and evaluate advanced HRGC instrumental procedures which show potential for improving the analysis of hydrocarbon jet fuels and various feedstocks. A gas chromatograph can be viewed as an assembly of individual components arranged to form a time invariant linear system. Accordingly, a systems approach has been used in this investigation to study, refine, and modify HRGC instrumentation. Originator supplied keywords include: High-resolution gas chromatography (HRGC); Shale oil; Fused silica capillary columns; Open tubular capillary (OTC); Multidimensional gas chromatography; Elution zone.

This book was released on 1985 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: The instrumental chemical analysis of complex organic mixtures requires efficient chromatographic techniques for the separation and analysis of the mixture constituents. Highly complicated mixtures, such as petroleum crudes, turbine engine fuels, shale oil, composited industrial organic liquid wastes, etc., require the use of high-resolution gas chromatographic (HRGC) techniques. The recent introduction of multidimensional gas chromatographic (MDGC) procedures shows promise of advancing HRGC techniques even further. The literature pertaining to multicolumn and multidimensional procedures was surveyed, and an MDGC system was assembled which used a previously optimized open tubular column gas chromatographic system. Special features were incorporated into this MDGC system which contained a two-column arrangement within a single temperature programmable chamber. The performance of the assembled MDGC system was evaluated and it was determined that for maximum performance of the assembled MDGC system was evaluated and it was determined that for maximum performance to be obtained from such coupled-column assemblies, considerable attention must be given to the design and behavior of each of the many different components within the entire chromatrographic flow path. It was concluded that MDGC represents a valuable additional approach for obtaining high-quality analyses of complex organic mixtures. Keywords: Multidimensional gas chromatography; 'Valveless' switching; Negative thermal gradient device; Pyrolysis oil.

Selection of methods for use on complex mixtures often involves the choice of more than one column; the separating capabilities of column packing and how they can be used in combinations are described and numerous examples are given. The handling of samples prior to separation and the calculation of results after separation, including calibration, are described. Throughout, special emphasis is given to the differences between gas analysis and the better documented liquid analysis.
Book Synopsis Analytical Gas Chromatography by : Walter Jennings
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.
Book Synopsis Quantitative Gas Chromatography for Laboratory Analyses and On-Line Process Control by : G. Guiochon
Download or read book Quantitative Gas Chromatography for Laboratory Analyses and On-Line Process Control written by G. Guiochon and published by Elsevier. This book was released on 1988-06-01 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is an invaluable new book on quantitative gas chromatography which explains how the method can - or should - be used for accurate and precise analysis. Gas chromatography is firmly established as one of the few major methods for the quantitative analysis of complex mixtures. It is fast, accurate and inexpensive, with a broad range of applications. It has however become very complex and involved: over 200 stationary phases, more than 10 detector principles and several very different column types are available from among the catalogs of over 100 manufacturers and major retailers. The progressive changes in the nature of gas chromatography have created new needs for information which are not satisfied by the literature presently available.This book provides a complete discussion of all the problems involved in the achievement of quantitative analysis by gas chromatography, whether in the research laboratory, in the routine analysis laboratory or in process control. For this reason the presentation of theoretical concepts has been limited to the essential, while extensive explanations have been devoted to the various steps involved in the derivation of precise and accurate data. This starts with the selection of the instrumentation and column, continues with the choice of optimum experimental conditions, then calibration and ends with the use of correct procedures for data acquisition and calculations. Finally, there is almost always a way to reduce errors and an entire chapter deals with this single issue. Numerous relevant examples are presented.The first part of the book presents the theoretical background, simple enough to be understood by all analytical chemists, but still complete and up-to-date. It discusses the problems of flow dynamics, retention and band broadening. The changes in band profile associated with column overloading are explained without much recourse to mathematics. The second part describes the gas chromatograph and discusses the properties of each of its parts: gas flow and pressure controller sampling system, oven, column switching valves, detectors. The different implementations, their advantages and drawbacks are discussed and compared. In addition, three chapters present packed column technology, open tubular column technology and some sophisticated new phase systems, respectively. The new phase systems described use adsorbents, modified by coating or grafting organic phase, and carrier gases containing vapors which are sorbed by the stationary phase and modify it, such as steam. The third part discusses the applications in qualitative and quantitative analysis. Calibration, peak integration, sources of errors arising from the various parts of the instrument as well as from the measurement process itself are carefully described in four detailed chapters. Methods to carry out accurate and precise analysis are presented. A last chapter is devoted to process control analysis and gives a number of detailed examples of applications. A lexicon explaining the most important chromatographic terms and a detailed index complete the book.This is a book which no chemical analyst should be without. It should be on the library shelf of all universities, instrument companies and any laboratory and plant where gas chromatography is used.
