摘要：
A gas chromatography system in which prefocusing of a sample analyte is provided through the use of an adsorbent coated porous layer open tubular trap tube. Through the use of an adsorbent coated collection device low boiling point components can be successfully trapped for preconcentration and injection at temperatures well above that necessary when employing conventional cryo-focusing.
