The design and performance of a multiparallel plate denuder able to operate at low and high-flow (3–30 L/min) for the collection of polycyclic aromatic hydrocarbon (PAH) vapor is described. The denuder, in combination with a micro orifice uniform deposit impactor (MOUDI) was used to assess processes...
