Abstract: A sampling device is constructed having an airflow (108) path from a size-selective inlet (158, 374) to a device outlet (160, 376), without using any tubing. The size-selective inlet (158, 374) includes at least one of an impactor, a filter, a cyclone, and an inhalable inlet (158, 374). The device includes a sampling assembly (212, 22) configured to be removably coupled directly to a sampling device housing (e.g., without using tubing), and an airflow assembly (132, 328) that may be constructed without using tubing.

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 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.
