Abstract

The principles of a new sample focusing technique in capillary gas chromatography are described. A solid-sorbent trapped sample is thermally released from the sample tube, transfered to a membrane chamber by a carrier gas and there retained by a gas separation membrane which is highly permeable to the carrier gas. After focusing in the membrane chamber the sample is injected on the column. This technique allows focusing and injection of highly volatile compounds in capillary GC without any coolant.
