ABSTRACT:
The present invention relates to apparatus for sampling and analysis of gas phase molecules. A source of negative pressure is used to draw gas phase molecules through a gas-permeable membrane. The gas phase molecules are then directed into an analyzer, suitably a gas chromatograph. The present invention also relates to methods of sampling and analyzing gas phase molecules above and below liquid and soil surfaces
