title: Evaluation of a dual-sorbent trap for monitoring organic compounds in air.
abstract: The performance of a new kind of multi-sorbent trap for use in the simultaneous determination of compounds of different volatility and polarity was investigated. The adsorbents employed for this purpose were Carbograph 2 and Carbograph 5. The performance of this trap was evaluated in terms of thermal desorption and solvent extraction recoveries of substances belonging to the main classes of organic compounds, at different amounts and volumes of air sampled corresponding to concentrations ranging from 0.1 to 1000 mg/m3. The tubes examined allowed the trapping of the compounds used and their complete desorption with the procedure best suited to the analytical problem.
