For my past sins, Leslie Ettre has given me the privilege of writing a few words to preface his excellent little book. It gives me great pleasure to do so, because of the many years of fruitful collabo ration we have had at Perkin-Elmer, because it is refreshing to see a treatise in gas chromatography in which the theoretical treatment has been bared to its essentials, without a mushrooming of formulae which, by means of an ever increasing number of parameters, account for more and more, and explain less and less, and because the author has recognized that the gas chromatographic column is a nearly passive element in its own right which deserves to have a treatise written nearly exclusively about it, just as electrical circuit theory can be discussed without elaborate references to vacuum tubes and meters. I wish this conscientiously written volume the success it deserves. M. J. E. GOLAY VII Preface Gas chromatography is a separation technique used primarily in analytical chemistry. Therefore, it is evident that special emphasis should be placed on that particular part of the apparatus in which the separation takes place. This part is the column, the heart of the gas chromatograph. The goal of researchers in the field of gas chromatography has been-from the beginning-to understand the separation process so that they might design columns with the best possible performance. Such investigation led M. J. E.

The only reference to provide both current and thorough coverage of this important analytical technique Static headspace-gas chromatography (HS-GC) is an indispensable technique for analyzing volatile organic compounds, enabling the analyst to assay a variety of sample matrices while avoiding the costly and time-consuming preparation involved with traditional GC. Static Headspace-Gas Chromatography: Theory and Practice has long been the only reference to provide in-depth coverage of this method of analysis. The Second Edition has been thoroughly updated to reflect the most recent developments and practices, and also includes coverage of solid-phase microextraction (SPME) and the purge-and-trap technique. Chapters cover: * Principles of static and dynamic headspace analysis, including the evolution of HS-GC methods and regulatory methods using static HS-GC * Basic theory of headspace analysis-physicochemical relationships, sensitivity, and the principles of multiple headspace extraction * HS-GC techniques-vials, cleaning, caps, sample volume, enrichment, and cryogenic techniques * Sample handling * Cryogenic HS-GC * Method development in HS-GC * Nonequilibrium static headspace analysis * Determination of physicochemical functions such as vapor pressures, activity coefficients, and more Comprehensive and focused, Static Headspace-Gas Chromatography, Second Edition provides an excellent resource to help the reader achieve optimal chromatographic results. Practical examples with original data help readers to master determinations in a wide variety of areas, such as forensic, environmental, pharmaceutical, and industrial applications.

The need for this second edition is dictated by developments that have occurred in this rapidly changing field and by sins of omission and sins of commission in the first edition. Projections available at the time of this writing indicate that gas chromoatography will remain the world's most widely used analytical technique for some time.
