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 796 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.

Download or read book Data Analysis and Signal Processing in Chromatography written by A. Felinger and published by Elsevier. This book was released on 1998-05-19 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an overview of the numerical data analysis and signal treatment techniques that are used in chromatography and related separation techniques. Emphasis is given to the description of the symmetrical and asymmetrical chromatographic peak shape models. Both theoretical and empirical models are discussed. The fundamentals of data acquisition, types and effect of baseline noise, and methods of improving the signal-to-noise ratio (either in time or in frequency and wavelet domain) are thoroughly discussed. Resolution enhancement techniques, such as curve fitting, deconvolution by Fourier and wavelet transforms, iterative deconvolution, Kalman filtering and multivariate methods of curve resolution are all discussed with several chromatographic examples. Quantitative analysis by peak area of peak height measurement, the precision and accuracy of the quantitation of stand-alone or overlapping and symmetrical or asymmetrical peaks are treated. In a separate chapter, guidelines are given for the use of transform techniques for the analysis of chromatograms. A statistical description of peak overlap is given in the final chapters. Since the concept of resolution has to be reconsidered when one separates complex mixtures, the problem of resolution and overlap is quantitatively discussed by means of statistical methods, and by using Fourier analysis of the complex chromatogram. Features of this book • The ultimate source of numerical techniques to enhance chromatographic data • Gives a detailed description of signal and resolution enhancement techniques in a manner applicable for enhancing not only chromatography, but also spectroscopic and other analytical signals • The first book with a thorough overview of the statistics of peak overlap. This is the first volume to encompass both the simple and more sophisticated methods for the numerical treatment of chromatograms. It is, therefore, the fundamental resource of numerical analysis methods for every analyst.

This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: During its short 20 year history High Performance Liquid Chro matography (HPLC) has won itself a firm place amongst the instrumental methods of analysis. HPLC has caused a revolution in biological and pharmaceutical chemistry. Approximately two thirds of the publications on HPLC are concerned with problems from this area of life science. Biotechnology, where it is necessary to isolate substances from complicated mixtures, is likely to give further impetus to the dissemination of modern liquid chromatog raphy in columns, particularly on the preparative scale. This book presents, by means of examples, the application of HPLC to various fields, as well as fundamental discussions of chromatographic methods. The quality of the analytical result is decisively dependent on the qualities of the equipment employed (by Colin, Guiochon, and Martin). Especially the demands are discussed that are placed on the components of the instrument including those for data acquisition and processing. The section on "quantitative analy sis" (by ABhauer, Ullner) covers besides the principles also the problems of ensuring the quality of the data in detail. The basic problems arising by enlarging the sample size to preparative di mensions and the requirements put on the aparatus are discussed in the section on "preparative applications" (by Wehrli).

Available in PDF, EPUB and Kindle. Book excerpt: The coupling of mass spectrometry or nuclear magnetic resonance to chromatography has broadened the possibilities for determining organic reaction mechanisms. And while many results have been published reporting these, even more can be achieved through modern computational methods. Combining computational and theoretical techniques with advanced chromatographic methods offers a powerful tool for quantitatively determining molecular interactions . This book presents the possibilities for characterising biological applications by combining analytical and computational chemistries. Written by the author of “HPLC: A Practical Guide” (RSC, 1999), the book examines not only the behaviour of biological reactions per se, but also describes the behaviour of biological molecules in chromatography systems. Various software packages are reviewed, and most computations can be performed on a standard PC using accessible software. Consideration is given to a variety of chromatographic techniques and strategies for high-sensitivity detection are presented. The first book of its kind, it will inspire readers to explore the possibilities of combining these techniques in their own work, whether at an industrial or academic level.
