Product Description
Gas chromatography remains the world's most widely used analytical technique, yet the expertise of a large proportion of chromatographers lies in other fields. Many users have little real knowledge of the variablesin 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 numberof 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 needto purchase an additional chromatograph or another mass spectrometer.The Second Edition of Analytical Gas Chromatography is extensively revised with selected areas expanded and many new explanations and figures. The 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 theVan 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 thespecial requirements of columns destined for mass spectral 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.
Key Features
* Incorporates nearly 60% new material
* Covers the newest concepts and materials for sample injection and stationary phases
* Presents detailed consideration of the influence of carrier gas velocity on practical aspects of chromatographic performance
* Contains a chapter on "Special Analytical Techniques" which includes consideration of selectivity tuning and fast analysis
* Provides a new section addressing the special requirements of columns to be used in mass spectral analysis
* Includes an improved program that greatly enhances the accuracy of the Van Deemter plots by more accurately depicting localized chromatographic conditions at each point in the column

 A must read book for serious chromatographer November 14, 2000
5 out of 5 found this review helpful
Analytical gas chromatography, second edition is an excellent reference book for those of us who take gas chromatography seriously, not as a fringe technology, nor learn enough to get by. The second edition was substantially revised from the first edition. Very up to date information with insights on why things appears in certain way. Chapter 5, variables in the gas chromatographic process, and chapter 6 (subsection 9), optimizing operational parameters for specific columns, and chapter 8 on selective tuning are very useful and invaluable.

This book has an excellent chapter on injections. The rest of the book contains things you can typically find in your user's manual. If you are interested in knowing every single aspect of the GC, this would be a good book. If you are just trying to get the GC up and running with a new compound, this may not be your best bet. Too much information and not enough time to absorb it all.
