ABSTRACT:
A sampling inlet for sampling aerosols in atmospheric air comprises an inlet housing that has an air flow and an inertial particle classification device in a series flow path from an inlet opening in the sampler to a filter which collects the material. The sampler is a classification device of the virtual impactor type, utilizing nozzles that receive the flow carrying the aerosols, and a receiver tube that is aligned with the nozzle and spaced therefrom, with a major portion of flow being diverted from the space between the nozzle and the receiver tube. The heavier particles are carried by inertia into the receiver tube and then are carried off by minor flow of fluid that passes through the receiver tubes.
