membrane extraction with sorbent interface gas chromatography
A separation method where the sample is first transferred from one phase (the 'donor' or 'feed' phase) to another (the 'acceptor' or 'strip' phase) across a non-porous non-polar polymer membrane. The membrane extracts the analytes from their matrix, and these are subsequently trapped on a polymeric trap with a porous sorbent using a carrier gas stream. In the second step, the mixture in the carrier gas stream is further separated by gas chromatography.
