Download or read book Stationary Phases in Gas Chromatography written by H. Rotzsche and published by Elsevier. This book was released on 1991-08-21 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary aim of this volume is to make the chemist familiar with the numerous stationary phases and column types, with their advantages and disadvantages, to help in the selection of the most suitable phase for the type of analytes under study. The book also provides detailed information on the chemical structure, physico-chemical behaviour, experimental applicability, physical data of liquid and solid stationary phases and solid supports. Such data were previously scattered throughout the literature. To understand the processes occurring in the separation column and to offer a manual both to the beginner and to the experienced chromatographer, one chapter is devoted to the basic theoretical aspects. Further, as the effectiveness of the stationary phase can only be considered in relation to the column type, a chapter on different column types and the arrangement of the stationary phase within the column is included.The secondary aim of this book is to stimulate the development of new and improved standardized stationary phases and columns, in order to improve the reproducibility of separations, as well as the range of applications.

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.

Book excerpt: In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.
