Abstract: Embodiments of the invention collect solid, vapor, and/or biological components of the air in air-sampling cartridges that are then transported to an off-site location by pneumatic pressure. Operation proceeds by first collecting a sample of air in an air-sampling cartridge in a sampling position, then rotating a wheel assembly to move the now-used sampling cartridge into a transport position while simultaneously moving an unused sampling cartridge into the sampling position, and finally using pneumatic pressure to push the used sampling cartridge in the transport position to an off-site location via a transport tube. The sampling operation can begin again while the transport operation is in still in progress. These operations can be pre-programmed locally or triggered by remote communication. Continued operation is possible due to a plurality of unused air-sampling cartridges retained in the wheel assembly. Since operations can be triggered remotely and air samples are autonomously transported off site, embodiments of this invention eliminate an unnecessary risk to human health that is created by other air-sampling devices, which require an operator to be present at a potentially hazardous sampling site to activate the device or retrieve air samples. Additionally, embodiments of the invention can be installed pre-emptively to eliminate the risk to human health that is created when an operator must deliver a portable air-sampling device to a potentially contaminated sampling site. Furthermore, embodiments of the invention allow rapid retrieval of air samples following sample collection, which can expedite analysis and identification of aerosols and consequently help minimize human exposure to potentially dangerous and life-threatening chemical and biological contaminants.

Abstract: An apparatus includes a sample receiving port and an inlet assembly configured to be positioned adjacent to the sample receiving port. The inlet assembly defines a volume for receiving a sample and includes a gap that defines an extraction port. The extraction port is configured to extract one fluid flow to facilitate another fluid flow toward the sample receiving port. The extraction port can be configured as an annular flow port around the sample receiving port. In some instances, the apparatus also includes a curtain port positioned apart from the sample receiving port and the extraction port. The curtain port can be used to guide fluid away from interior surfaces of the inlet assembly and toward the sample receiving port, and/or to provide an environment of controlled air, and/or to isolate the sample receiving port from external sources of contamination.
