摘要： An abrasive particle detection system includes a fluid circulation system, a probe assembly, a monitoring circuit, and an operator indicator The probe assembly includes an orifice from which a stream of fluid emerges, and a probe having a face upon which the stream at least partially impinges The probe face includes an insulative substrate and a conductive film formed on the substrate Abrasive particles in the fluid stream abrade the conductive film, changing its electrical resistance. A monitoring circuit is utilized to observe these changes, and when they correspond to a concentration above a pre-selected level, an operator indicator is triggered. The system may include an electronic controller coupled to the monitoring circuit. which can account for variables such as temperature, viscosity, and/or pressure in the fluid circulation system.

摘要： An automated cascade impactor is disclosed and comprises a vertical array of a plurality of impactor stages, and a vertical array of isolation stages, wherein the vertical array of the isolation stages comprises pairs of isolation stages between which impactor plates, removed from respective ones of the impactor stages are effectively sandwiched between each pair of isolation stages. Still further, each compactor stage is likewise sandwiched between and upper and a lower pair of the isolation stages.

摘要： The invention generally provides devices and methods for sampling, detecting and/or characterizing particles, for example, via collection, growth and analysis of viable biological particles such as microorganisms. Devices and methods of the invention include particle samplers and impactors for collecting and/or analyzing biological particles in manufacturing environments requiring low levels of particles, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products, such as sterile medicinal products. Devices and methods of the invention incorporate an integrated sampler and impact surface, such as the receiving surface of a growth media, in a manner to minimize, or entirely eliminate, risks associated with user handling, such as the occurrence of false positive determinations due to contamination of the impact surface during particle sampling, growth or analysis processes.

摘要： In example embodiments, particle collection efficiency in aerosol analyzers and other particle measuring instruments is improved by a particle capture device that employs multiple collisions to decrease momentum of particles until the particles are collected (e.g., vaporized or come to rest). The particle collection device includes an aperture through which a focused particle beam enters. A collection enclosure is coupled to the aperture and has one or more internal surfaces against which particles of the focused beam collide. One or more features are employed in the collection enclosure to promote particles to collide multiple times within the enclosure, and thereby be vaporized or come to rest, rather than escape through the aperture.

摘要： A particle impact device for a hand-held trace particle detection system includes an intake manifold that includes a first conduit defining an intake port. The intake port defines a first transport area. The intake manifold also includes a second conduit coupled to the first conduit. The second conduit defines a discharge port that defines a second transport area. The first transport area is greater than the second transport area. The particle impact device also includes a combined deposition and deflection apparatus positioned downstream of the discharge port. The combined deposition and deflection apparatus defines a deposition and deflection surface positioned a predetermined distance from the discharge port. The deposition and deflection surface is configured to deflect a fluid stream and collect at least a portion of particles entrained in the fluid stream.

摘要： Described is an air sampling device which comprises a body section, an inlet for allowing air to enter the body section, a first outlet for allowing air to exit the body section towards a collection vessel; and a second outlet for allowing air to exit the body section towards a vacuum pump. The inlet, first outlet and second outlet are configured such that when the second outlet is connected to a vacuum pump, a major air flow path is created between the inlet and the second outlet and a minor air flow path is created between the inlet and the first outlet, and airborne particles which enter the device through the inlet follow either the major air flow path or the minor air flow path according to their size. Also described is an apparatus and an automated method for detecting airborne biological particles.
