摘要： As an elegant solution for minimizing false positives returned by a sensor tuned to an analyte molecule, filters constructed of carbon nanotubes are positioned relative to the sensor to limit the sensor to being exposed to molecules within a defined range of sizes, with too-big molecules being excluded from reaching the sensor by one filter, and too-small molecules being pumped out through another, finer filter before the sensor is operated.

摘要： A personal nanoparticle sampler is disclosed to include a pre-classifier, a nozzle, a connector and a final filter pack. The connector and the final filter pack respectively accommodate a particle-sizing filter and a final filter to collect nanoparticles smaller than a diameter. The pre-classifier removes large particles to avoid clogging of the connector. The nozzle raises the airflow velocity to reduce the cut-off diameter of the particle-sizing filter without increasing the total flowrate, allowing the personal nanoparticle sampler to be used with a personal sampling pump.

摘要： A detector for optically detecting biological aerosols in a sample volume using non-imaging optical components (NIOCs) includes a light source configured to stimulate bio-fluorescence of tryptophan or nicotinamide adenine dinucleotide. In at least one embodiment, a sample volume and each non-imaging optical component are defined by surface features in each of a first monolithic structure and a second monolithic structure, when the first monolithic structure and the second monolithic structure are disposed in a facing relationship. In at least one embodiment, each NIOC comprises a compound parabolic collector. To facilitate volume production, the monolithic structures can be molded. Preferably, the sample is a volume of a gaseous fluid, such as air.

摘要： A device for the separation of small particles or cells from a fluid suspension of the same is described. The device includes a coaxial tubular design in which the inner tube is a micro porous tube that allows the passage of liquids and certain particulates up to a certain size cut-off, and the outer tube allows for the collection of passed fluids. Inlet and outlet ports allow the introduction and flushing of components of interest. Embodiments of the device can be used for the separation of blood components, the sequestering of micro spheres used in micro-sphere-based immuno assay, and sample filtration. Other applications are not precluded. Another field of application for this device is in the separation of plasma from red blood cells. The red blood cells will not pass through the membrane due to their size, but plasma will.

摘要： Device of modular construction which permits the simultaneous or not-simultaneous recording and characterization of solid and liquid particles and gaseous components of engine exhaust gases on various test supports, with only small or no modification of the test support. Methods are based on individual or combined usage of laser scattering techniques, laser-induced breakdown spectroscopy, laser-induced ionization spectroscopy, laser-induced atomic fluorescence spectroscopy, IR-/VIS-/UV-laser absorption spectroscopy and laser-induced incandescence. Use of individual or combined usage of such devices permits the analysis of raw exhaust gas, the conditioned and/or treated exhaust gases for monitoring and checking working pattern of engine, individual components of exhaust gas treatment and/or total system on test beds and on vehicle and can be used for control of motor and/or exhaust components, such as catalysts and particle filters, on test beds and in driven usage, e.g., in connection with, or as part of, on-board diagnostic system.

摘要： A three-stage dust sampler makes use of a porous foam as the impactor substrates. The sampler includes an annular inlet which conforms to ISO/CEN/ACGIH inhalable sampling criteria, two impactor stages to classify thoracic and respirable particles and a final filter to collect respirable particles after the impactors. For 100 ppi polymer foam substrates, and a flow rate of 3.2 lpm, the collection efficiency curves of the thoracic and respirable dust matches ISO/CEN/ACGIH criteria when the jet-to-plate distance is 1.0. The cut-off aerodynamic diameter is 9.6 and 4.0 μm for the first and second impactor stages, respectively, and √{square root over (stk50)} is 0.39 for both stages. The collection efficiencies for solid particles is equal to that for liquid particles, indicating that there is no solid particle bouncing from the foam substrates.
