An interface which allows the thermal desorption of large (about 5 cu m) Tenax-GC cartridges to fused silica capillary gas chromatography columns has been developed and tested. The interface makes use of a small Tenax-GC cartridge for intermediate trapping and a secondary thermal desorption at 270C with a carrier flow rate of 2.5 mL/min to transfer the analytes to the subambient column. The determination of several nonpolar aqueous organic compounds including o-dichlorobenzene, 1,2,4-trichlorobenzene, and naphthalene at the ng/L level with + or - 2% precision is demonstrated.
