Volatile organic compounds (VOCs) were sampled by Radiello
diffusive samplers. These samplers consist of a cylindrical adsorbing
cartridge placed inside a cylindrical diffusive body. Radial symmetry
offers important advantages: better capacity for enrichment
of the substrate; and reproducibility and stability with air speed.
Bruno et al. (2007) tested Radiello diffusive samplers by using
them in the detection of odorous compounds on solid waste treatment
plants, and concluded that the diffusive sampling method is
highly reproducible.
