Abstract: A modified Steam Jet Aerosol Collector (SJAC) for semivolatile organic compounds has been investigated. Gas phase and particle phase were investigated separately. The SJAC is based on a water condensational growth sampling system. For determination of gaseous compounds an XAD adsorbent cartridge was applied after particle collection. Collection particle efficiency was examined using hydrophobic soot and octacosane particles. To estimate the bias caused by the transfer of components from the gaseous to the particle fraction, individual gaseous organic with different polarity were examined. High collection efficiency and negligible cross-contamination of gaseous compounds in the particle fraction was observed.

Keywords: semi volatile organic compounds; aerosol sampling; gas-particle portioning; steam jet aerosol collectors; SJAC; gas phase; particle phase; hydrophobic soot; octacosane particles.
