This book gives a comprehensive, up-to-date review of all selective detectors used in combination with gas chromatography. For each detector, the historical background, design and principle are described, and the working parameters affecting the detector performance are analyzed critically and in detail. The analytical possibilities of the detectors and the main characteristics such as sensitivity, noise and minimum detectability are discussed. All the selective detectors that are currently used are discussed in detail. Combinations of GC with other techniques such as plasma emission spectroscopy, atomic absorption spectrometry, ion-selective electrodes, piezoelectric sorption detector, mass spectrometry and infrared spectroscopy are discussed briefly.Chromatographers and users of gas chromatographs, especially in the field of environmental protection, agriculture, clinical chemistry, and toxicology will find the book useful to their work. Institutes and organisations dealing with analytical chemistry will also find it of interest.

Air pollution determination is one of the most important fields of gas chromatography application in practice. This book provides a systematic description of the main stages of air pollution determination, ranging from sampling problems to the quantitative estimation of the acquired data. Special attention is paid to the problem of gas, vapor, spray and solid particles extraction from air. The main methods of sampling procedure, namely, container utilization, cryogenic concentration, absorption, adsorption, chemisorption and filter usage, and successive impurities extraction are also handled. Sorption theory and the problems of sorption and desorption efficiency for hazardous impurities being extracted from traps with sorbents are discussed in detail. The practical utilization of different sorbents (silica, activated carbon, polymers etc.) to carry out sampling procedures for 200 main pollutants with known TLV (USSR and USA) is also considered. This highly informative book, reflecting several insufficiently known techniques as well as the experience of both western and Soviet researchers, should be of interest to both beginners and skilled researchers.

Gas Chromatograpic Environmental Analysis is the first, truly complete, up-to-date, homogeneous coverage in book form, of the analytical techniques applied to the chemical study of environment. The book describes the use of gas chromatograpy in environmental analysis. After an introduction in the fundamentals of gas chromatograpy and a critical review of the different column types, the author describes the necessary instrumentation, with particular attention on the sample injection, detection and calibration systems. Special attention is paid to trace analysis which is important, e.g., in the recognation of specific fluorocarbons in the atmosphere. In addition, the author looks briefly at other techniques such as HPLC and mass spectrometry to give a complete picture of environmental analysis of today and tomorrow. Because it is written for chemists, analytical chemists in both industrial and academic contexts, chemical engineers, industrial hygienists, environmental biologists and geologists, the book pays particular attention to the methods that have been officially adopted in the U.S. and other highly industrialized companies. It is certain to be a welcome addition to the librairies of chemical companies, town and regional administrators, universities, and government research centers.

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.
