BIOSIS COPYRIGHT: BIOL ABS. A high-volume air sampler was developed to collect organic compounds in the gas and particulate phases at flows up to 1.4 m3/min. Quartz fiber or Teflon membrane filters can be employed; use of a backup filter allows correction for the direct adsorption of gaseous analytes to the filter. Most of the filtered air passes through two 1.27 cm thick polyurethane foam sheets (PUFSs) in series; the remainder passes through two Tenax cartridges in series. The thin, filter-size (20 cmssure drop. An adequate sample volume can be obtained in a minimum amount of time, minimizing the probability that atmospheric concentration fluctuations will cause volatilization losses from, or adsorption gains to particles on the filter. With sample volumes of 500-700 m3, at PUFS was 30% for compounds less volatile than octadecane (C18) and phenanthrene. Good agreement was obtained for the compounds determined on both the PUFSs and the Tenax beds.
