Blood Alcohol Content by Headspace/Gas Chromatography

Wed, 08/04/2010 - 9:04pm

Learn about the basic theory, practices and parameters involved in blood alcohol analysis. Sample handling, instrumental parameters affecting headspace equilibrium, extraction and injection, matrix effects/matrix modifications and qualitative/quantitative acceptance criterion will be discussed.

Detailed comparisons will be made between several static and dynamic gas phase extraction techniques for volatiles associated with Blood Alcohol Content. Sample introduction to gas chromatography will include direct liquid injection and 3 different types of headspace extraction/injection techniques. Primary emphasis will be made on the technique of balanced pressure equilibrium headspace extraction.
