Abstract
The sampling of vapor-phase organics in the presence of reactive inorganics using the Tenax GC sampling cartridge was investigated. To differentiate between pollutants in air and those formed from in situ artifact reactions, deuterated organics were employed in both laboratory and field experiments; and any subsequent artifact products were detected by capillary gas chromatography/mass spectrometry/computer (GC) squared 2/MS/COMP) techniques. Artifacts produced by Tenax GC itself and by reactions between adsorbed species were investigated using statistical methods.
