摘要：

Solid-phase extraction tubes were evaluated as traps for off-line supercritical fluid extraction. Normal- and reversed-phase traps were studled with hydrocarbons, phenols, and a "test mixture" in order to determine the trapping efficiency. These traps were then used for the extraction of PCBs from river sediment. Polyethylene frits were also investigated for their use as solid-phase traps in SFE.
