Gas Chromatography: Analytical Chemistry by Open Learning

Gas Chromatography: Analytical Chemistry by Open Learning

By Ian A. Fowlis

Approaches the subject from the perspective of a chromatographer who needs to know enough theory to make the best use of a chosen technique. Emphasizes the actual application of the methods--not just the theories on which they are based. This edition features a number of advances in the field since publication of the first volume. These include new chapters on high resolution gas chromatography (GC), GC detectors and classification of GC. Self-assessment questions ensure full understanding of the concepts.

Analytical Gas Chromatography, Second Edition

Analytical Gas Chromatography, Second Edition

By Walter Jennings, Eric Mittlefehldt, Phillip Stremple

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

Basic Gas Chromatography

Basic Gas Chromatography

By Harold M. McNair, James M. Miller

Gas Chromatography (GC) is undoubtedly the most widely used technique for the separation and analysis of volatile compounds. Yet comprehensive guides to contemporary GC theory and practice are surprisingly hard to find.

Basic Gas Chromatography fills this significant void in the GC literature. Written by two well-known practitioners and educators in GC, it offers thorough coverage of the basic principles and techniques of modern gas chromatography.

Designed to serve as a primer/working reference for bench chemists and as a textbook for upper-level undergraduate and graduate students, it presents the fundamentals in a straightforward and logical fashion. Theoretical issues are explained without complicated equations and derivations and always in terms of how they relate to practical operating principles. Timely, comprehensive, and accessible, Basic Gas Chromatography:

* Provides a balanced presentation of theory and practice

* Includes both capillary column and packed column chromatography

* Uses the new IUPAC terms throughout, cross-referenced to traditional terms and symbols

* Offers a wealth of helpful hints, step-by-step guidelines, and trouble-shooting tips

* Briefly covers GC-MS, headspace analysis, chiral analysis, solid phase microextraction, and other cutting-edge topics.
