Abstract: | A method was developed for sampling and selective quantitative determination of typical volatile organic compounds (VOCs)
in ambient urban air. A mobile and self-contained dual-channel air sampling tool based on solid phase adsorption was constructed.
A simple calibration procedure circumventing the adsorption/desorption process was designed. The method was validated for
seven “key-analytes”: n-hexane, 3-methyl-2-pentene, benzene, tetrachloroethene, styrene, 1,2,4-trimethylbenzene and acetophenone.
The complete air sampling equipment is easily accommodated in a business suitcase. The lower limits of the practical working
ranges are between 0.1 μg m–3 (tetrachloroethene) and 1.2 μg m–3 (benzene). Air samples were collected at a location in Salzburg with heavy motor vehicle traffic and measured in order to
prove a satisfactory method performance under practical monitoring conditions.
