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.

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 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.
