Abstract

An apparatus for studying aerosol includes a test chamber having panels defining an enclosed interior volume. The panels have (i) a first wall having a surface defining an interior of the test chamber, (ii) a second wall defining an exterior of the test chamber, (iii) a void space between the first and second walls, (iv) a panel inlet in communication with the void space, and (v) a panel outlet in communication with the void space. The apparatus includes a chamber inlet port and a chamber outlet port, each extending through one of the panels and in communication with the enclosed interior volume. The apparatus includes a fan disposed in, and positioned and configured to mix air in, the enclosed interior volume. The apparatus includes a trap port extending through one of panels and includes a valve to permit sampling of the contents in the enclosed interior volume.
