Abstract: A portable sampling device includes a housing at least partially enclosing an inner chamber and an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path. The airflow assembly includes a portion of a printed circuit board (PCB); a manifold configured to be sealably coupled to the portion of the PCB to define at least one airflow channel disposed between an inner surface of the manifold and an outer surface of the PCB; and one or more pumping elements positioned on the PCB.

Abstract: A sampling device is constructed having an airflow path from a size-selective inlet to a device outlet, without using any tubing. The size-selective inlet includes at least one of an impactor, a filter, a cyclone, and an inhalable inlet. The device includes a sampling assembly configured to be removably coupled directly to a sampling device housing (e.g., without using tubing), and an airflow assembly that may be constructed without using tubing.
