ABSTRACT
Headspace technology was invented in the late 1960’s. Globally, it is used in many industries including chemical, pharmaceutical, environmental and forensics. In the latter case, the results from measuring blood alcohol content stands up in a court of law confirming the validity of using headspace as a sample introduction technique for gas chromatography for quantitative reporting. A focusing trap was added in the early 2000’s enabling sensitivity improvements by over 100 times.
This talk will focus on environmental applications including:
• EPA method 524 and 8260;
• Benzene, Toluene, Ethyl Benzene, and Xylenes (BTEX) in drinking water (fast analysis);
• Dioxane in water;
• Gasoline through diesel contaminants in water.
The presentation will include an introduction of headspace theory. The advantages and benefits of headspace over other alternative sample introduction techniques for the measuring of volatile and semi-volatile organic compounds (VOC and SVOC). The analytical performance attained using headspace from several environmental matrices.
