  • Patent number: 10317320
    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 advancing a cartridge 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 cartridge assembly.

  • Patent number: 10254201
    Abstract: Embodiments of the invention can sample particulates, aerosols, vapors, and/or biological components of ambient air utilizing spherical air-sampling filters. Components of the embodiments may include a hopper for holding spherical air-sampling filters, an air-sampling manifold configured to deliver an air-sampling filter from the hopper to a sampling location, and an air compressor to perform an air sampling operation and to transport a used air-sampling filter away from the sampling location. Operation of some embodiments may begin by rotating a slotted drum within the air-sampling manifold to deliver an air-sampling filter from the hopper to the sampling position. Operation may continue by using the air compressor to draw air from an ambient environment through the air-sampling filter. After sampling is complete, the air compressor may be utilized to pneumatically transport the used air-sampling filter away from the sampling position to a filter retrieval location via an output tube.

  • Publication number: 20170328815
    Abstract: Embodiments of the invention can sample particulates, aerosols, vapors, and/or biological components of ambient air utilizing spherical air-sampling filters. Components of the embodiments may include a storage magazine for holding a plurality of spherical air-sampling filters, an air-sampling manifold configured to deliver an air-sampling filter from the storage magazine to a sampling location, and an air compressor to perform an air sampling operation and to transport a used air-sampling filter away from the sampling location. Operation of some embodiments may begin by rotating a slotted drum within the air-sampling manifold to deliver an air-sampling filter from the storage magazine to the sampling position. Operation may continue by using the air compressor to draw air from an ambient environment through the air-sampling filter.

    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.
