Head-Space Analysis and Related Methods in Gas Chromatography

This monograph examines the principles and applications of headspace analysis--a new and rapidly developing independent field in gas chromatographic analysis based on the use of "out of column" phase equilibria and partition coefficients in gasliquid states. Different variations of quantitative analysis, including techniques for increasing analytical sensitivity and the calibration of chromatographs, are also presented. The advantages of analytical and physicochemical applications are illustrated by such examples as the determination of volatile organic impurities in natural and industrial discharge waters, polymers, and air, and also by examples in medical, biological, food, agricultural, and other types of research. Also included are discussions of the automatic instruments and technical equipment needed to conduct these analyses. A basic knowledge of the principles of gas chromatography and physical chemistry (an understanding of phase equilibria) is assumed. The book, therefore, can be used by a wide circle of readers, from teachers and students in advanced courses dealing with analytical chemistry and gas chromatography, to workers at testing and analytical laboratories. The book will also prove valuable to individuals involved in medicinal, sanitation and forensic chemistry, environmental protection, ecology and criminology.B. V.
