摘要
An apparatus and method for separating and analyzing a component of a fluid sample that is considered to be a contaminant, and particularly, that is or may be an organic material. The invention is predicated on the introduction of the sample fluid in a pulsed manner via a first carrier fluid into a feed chamber. A membrane is located between the feed chamber and an exit chamber, and in fluid registry therewith. When the sample enters the feed chamber, the component to be separated and analyzed can permeate the membrane, and thus passes through the membrane to the exit chamber, and then enters a second carrier fluid which carries it to a detector for analysis. The detector may be a gas chromatograph (GC), mass spectrometer (MS) or the like.
