The URG Versatile Air Pollutant Sampler (VAPS) allows for the simultaneous measurement of a variety of air quality parameters. The virtual impactor used in the VAPS is a modification of the virtual impactor system approved by the USEPA for compliance monitoring of PM-10. The VAPS virtual impactor operates at 32Lpm. The coarse particles travel straight through the center channel and are collected on a filter. The fine particles travel through the left and right channels. Annular denuders on the left channel collect any reactive acidic and basic gases. A polyurethane foam sampler (PUF) on the right channel collects higher molecular weight organic vapors.
