Abstract
The use of a KI-coated annular denuder for eliminating NO2 interference during sampling of airborne particulate matter on filter media is proposed. The performances of this novel diffusion sampler were evaluated in a series of practical tests concerning optimization of the sorption efficiency of NO2. Results pointed out that a properly sized annular denuder under 1 m long could be able to remove HO2 before collecting aerosols at laminar airflows as high as 15 1 min−1.Keywords
