Description: Close to 60 percent of Analytical Gas Chromatography, Second Edition has been revised from the previous edition of this respected book. This expanded and updated version is the first in nine years, incorporating new methodologies and developments into this popular introduction to gas chromatography.

"Eminently readable...It is the sort of reference book that should be on the shelf of every laboratory that contains a gas chromatograph". -- Brian Bush, Wadsworth Laboratory. New York State Department, in Analytical Chemistry

"The treatment is superb and complete. The author's style of writing makes the book easy to read and interesting. Thus, if you desire a well-written, interesting treatment on the practical considerations involved in gas chromatography, emphasizing the selection, installation, evaluation, application, and basis for the use of open tubular glass capillary columns, this book should be your choice". -- Peter F. Lott, University of Missouri-Kansas City, in The Journal of American Chemical Society

Gas chromatography remains the world's most widely used analytical technique. However the expertise of a large proportion of chromatographers lies in other fields, and many users have little real knowledge of the variables in the chromatographic process, the interaction between those variables, how they are best controlled, how the quality of their analytical results could be improved, and how analysis times can be shortened to facilitate the generation of a greater number of more reliable results on the same equipment. An analyst with a more comprehensive understanding of chromatographic principles and practice, however, can often improve the quality of the data generated,reduce the analytical time, and forestall the need to purchase an additional chromatograph or another mass spectrometer.

The Second Edition of Analytical Gas Chromatography is extensively rewritten with selected areas expanded and many new explanations and figures. The revised section on sample injection has been updated to include newer concepts of split, splitless, hot and cold on-column, programmed temperature vaporization, and large volume injections. Coverage of stationary phases now includes discussion, applications, and rationale of the increased thermal and oxidative resistance of the newly designed silarylenepolysiloxane polymers. Conventional and "extended range" polyethylene glycol stationary phases are examined from the viewpoints of temperature range and retention index reliabilities, and the chapter on "Variables" has been completely rewritten. The ways in which carrier gas velocity influences chromatographic performance is considered in detail, and includes what may be the first rational explanation of the seemingly anomalous effects that temperature exercises on gas viscosity (and gas flow). The practical effects that these changes cause to the chromatography is examined in pressure-, flow-, and "EPC-" regulated systems. "Column Selection, Installation, and Use" has been completely rewritten as well. The accuracy of the Van Deemter plots has been greatly enhanced; a new program corrects for the first time for the changes in gas density and diffusion that occur during the chromatographic process because of solute progression through the pressure drop of the column. A new section has also been added on meeting the special requirements of columns destined for massspectral analysis. The chapter on "Special Applications" has been expanded to include considerations of "selectivity tuning", of fast analysis, and the section of Applications has been thoroughly updated and expanded.
-- Builds on the success and reputation of the original book, with nearly 60% new material
-- Includes new methodologies such as purge-and-trap, programmed temperature vaporization, and chiral phases
-- Incorporates advancements in PLOT and SCOT column considerations
-- Appeals to the large number of practicing chromatographers with little or no training in the subject
