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.

Respirable and thoracic sampling inlet assemblies

A portable sampling device includes a sampling housing at least partially enclosing an inner chamber; at least one pumping element disposed within the inner chamber and configured to facilitate airflow through the device; and at least one gas sensor disposed within the inner chamber and configured to detect and/or characterize one or more gases in the airflow.

Sampling device for exposure measurement of particles and gases

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.

Portable air sampling device

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.

A thermophoretic sampler includes a sample assembly into which a removable sample cartridge can be inserted. The sample cartridge holds a substrate that, upon insertion, is exposed to a sample chamber. Thermophoresis is induced in the sample chamber, causing nanoparticles to be deposited on the substrate.

Thermophoretic sampler

A combustion chamber, having an upper part and a lower part, may include an annular constriction, in combination with the combustion chamber, to aid in directing partially combusted gases such as carbon monoxide away from the periphery of the combustion chamber back toward its center, and into the flame front. The annular constriction may also impede the flow of partially combusted gases located at the periphery, thus increasing the time these gases spend within the combustion chamber and increasing the likelihood that any products of incomplete combustion will undergo combustion. The combustion chamber may further comprise a dual burner cooktop for directing combustion gases and exhaust to multiple cooking vessels. In further embodiments, the combustion chamber may be made of, lined, or clad with a metal alloy comprising iron, chromium, and aluminum.
