A series of fourteen experimental sampling runs were carried out at a field site to collect data from several ambient air monitoring methods for volatile organic compounds (VOCs). Ambient air was drawn through a sampling manifold and was continuously spiked with volatile organic compounds to give concentrations 1 to 3 micrograms/L above background air. The spiked compounds were chloroethene, 1,1-dicholorethene, dichloromethane, 3-chloropropene, 1,1,2-trichloro-1,2,2-trifluoroethane, trichloromethane, 1,2-dichloroethane, 1,1,1-trichloroethane, benzene, tetra chloromethane, trichloroethene, toluene, tetrachloroethene, chlorobenzene, and 1,2-dimethylbenzene. Special canisters were utilized to collect whole air, time-integrated samples. An automated gas chromatographic system using capillary column separation and multiple detectors was used for analysis. These samples were analyzed by standard gas chromatographic/mass spectrometric techniques. For Tenax, precision values ranged from 8 to 16 percent.
