GC second edition available

The Second Edition of Analytical Gas Chromatography is extensively revised and published, with selected areas expanded and many new explanations and figures, including updates on a number of new concepts in the field of sample injection.

Gas chromatography remains the world’s most widely used analytical technique, yet 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, how these are best controlled, and how the quality of analytical results could be improved.

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.

In light of this, 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.

The publication’s 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, while new chapters on applications also feature.
