Abstract: A gas processing device such as an aerosol exposure monitor is configured for acquiring chronic data, acute data, or both simultaneously, and may include a pump and a noise dampening device. The noise dampening device may include an elastomeric membrane between an inlet chamber and an outlet chamber. In another aspect, an aerosol exposure monitor may include an impactor, a collection filter, and a nephelometer that includes a sample chamber integrated with an aerosol flow path associated with the impactor and collection filter.

Abstract: A gas processing device includes a sample inlet defining a gas flow path into a housing, and a pump and a noise dampening device disposed in the housing. The noise dampening device includes an inlet chamber, an outlet chamber, and an elastomeric membrane interposed between and fluidly isolating the inlet chamber and the outlet chamber. The inlet chamber is interposed between the sample inlet and the pump inlet, and the outlet chamber communicates with the pump outlet.
