Abstract: A device, an improvement upon a funnel, to enable immiscible liquids to be dispensed from an inverted bottle to augment a new, in-situ method to extract chemicals from water directly within sampling containers.

Abstract: A bottle attachment designed to facilitate the separation of immiscible solvents following the liquid-liquid extraction of organic compounds from water in original sampling bottles.

Abstract: A method and apparatus for extracting organic chemicals from water. In particular an apparatus and procedure to effect the liquid-liquid extraction of semi-volatile organic compounds from water in original sampling bottles by rotating a mixture of solvent(s) and/or solvent and salt with sample water for a prescribed period of time at a prescribed rate.

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 At the testing facility, at least a portion of the tetraglyme is withdrawn from the container, dispersed in water, and subjected to a gas chromatography/mass spectrometry procedure to analyze the volatile organic components.

Abstract: A method for removing volatile organics from landfill gas, in which the 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.
