Download or read book Detectors for Capillary Chromatography written by Herbert H. Hill (Jr.) and published by Wiley-Interscience. This book was released on 1992-10-30 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently there has been a great deal written about the benefits capillary chromatography offers in the area of separation and analysis. However, there is a need now to focus on the detection methods commonly used with capillary chromatography. Detectors for Capillary Chromatography presents the writings of 20 authorities who describe the unique features of each detector that are required for successful interfacing with capillary columns. Fused silica column technology has now advanced to the point where tremendous separation power is available. However, as these chapters show, without the ability to "see" the separated components, this high resolution is wasted. While it is true that the column is the heart of the chromatographic process, the detectors are the "eyes" that make the separation visible. A number of methods for "looking" at the results of chromatographic separations have been developed and each provides a different "view". To understand the information gained in high resolution chromatography, you must be able to interpret correctly the view provided by the detector. This book will provide you with the necessary insights into how you can accomplish that. The outstanding contributors to this book are all experts in the field. In many cases they are the researchers who originally developed the detector or have made major contributions to understanding its operation. This state-of-the-art text will be of immediate benefit to analytical chemists and physical chemists worKing with gas chromatography, who use this technique in environmental, industrial, or forensic investigations.

Download or read book Gas Chromatography written by A. B. Littlewood and published by Elsevier. This book was released on 2013-10-22 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas Chromatography: Principles, Techniques, and Applications, Second Edition, is a general textbook on gas chromatography suitable for users of the technique and for research workers. It does not presuppose any knowledge of the subject. Starting with an introduction to gas chromatography, the first half of the book is primarily concerned with the ability of gas chromatography to perform separations. The theory of the operation and design of gas chromatographic columns—both packed and open-tube—is described in detail, and it is shown how columns may be designed so as to secure any desired separation. Separate chapters discuss the thermodynamics of solution and the kinetics of chromatography. The third quarter of the book deals with detectors, which are the means of obtaining quantitative analyses by gas chromatography. It also contains a description of the union of gas chromatography with other techniques, and some indication of the use of the more sophisticated methods of handling gas-chromatographic data. The last quarter of the book is a single chapter in a series of sections, each dealing with the chromatography of a particular class of chemical compound

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.
