Abstract
A transpirated wall aerosol collection system includes a collector operable to receive a gas flow containing particulate matter. The system also includes a porous wall having a first surface and a second surface. The porous wall is operable to transpire a liquid from the first surface to the second surface. Particulate matter contained in the gas flow is deposited in the liquid on the second surface of the porous wall. A virtual impactor may be used with the system for concentrating the particulate matter contained in the gas flow.
