ABSTRACT:
The present disclosure concerns embodiments of a sampling apparatus that utilizes one or more cyclone separators to collect airborne particles from the atmosphere. In one representative embodiment, the sampling apparatus includes a collection-vessel retaining member that is adapted to be removably coupled to a collection vessel. The retaining member has an air-inlet conduit for permitting air to flow through the open end of the collection vessel and an air-outlet conduit for permitting air to exit the open end of the collection vessel. The airinlet conduit and the air-outlet conduit are configured to cause air flowing into the collection vessel to establishes a cyclonic flow path, which causes airborne particles to separate out from the air stream and collect in the collection vessel.
