    Abstract

    Trace-level vapor-phase organic components in tropospheric samples have been identified using combined glass capillary gas chromatography-mass spectrometry. Samples were collected on Tenax-GC sorbent from an aircraft sampling port at various locations over North America and the Atlantic and Pacific Oceans. The compounds found in these samples include n-alkanes (hexane to pentadecane), alkenes, benzene and alkylbenzenes, styrene, tetrachloroethylene, dichlorobenzenes, dimethyldisulfide, and benzaldehyde. The concentrations of benzene and toluene were determined to be in the range of <0.1 to 1.3 ppb and <0.1 to 5 ppb, respectively. These values are comparable to those found for land-based samples.
