Abstract: A portable sampler, the sampler including a sampler assembly having a housing that includes a receiver defined therein for interchangeably receiving a number of removable inlet assemblies, the removable inlet assemblies including a respirable inlet assembly and a thoracic inlet assembly. The respirable inlet assembly includes a hybrid cyclone assembly, the hybrid cyclone assembly including an impaction stage and a cyclone in series. The thoracic inlet assembly includes an inlet slot configured to function as a size-selective inlet. Another thoracic inlet assembly includes a housing having a number of openings configured to receive a sample airflow; an inlet insert through which an inlet aperture is defined; a prequalification chamber defined between a lower surface of the housing and an upper surface of the inlet insert; and a protrusion extending downward from the lower surface of the housing into the inlet aperture of the inlet insert to from an inlet slot.

Abstract: Methods and systems for characterizing particles in an aerosol are disclosed. A system includes a collection container that utilizes the principles of elutriation to collect particles of selected aerodynamic diameter ranges within a measurement region. A particle detector is used to detect and characterize particles that have settled into the measurement region.

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.
