Abstract
A method and apparatus for sampling and analyzing gas. In particular landfill gas, which consists primarily of methane and contains volatile organic components, is passed through a quantity of liquid tetraglyme to cause the volatile organic components to be absorbed in the tetraglyme. The tetraglyme containing the absorbed volatile organic components, is then disposed in a sealed container and transported to a laboratory testing facility. At the testing facility, at least a portion of the tetraglyme is withdrawn from the container, dispersed in water, and subjected to a gas chromatography/mass spectrometry procedure to analyze the volatile organic components.
