摘要： A particle detector apparatus for optically ascertaining a number of particles arranged on a surface of, for example, a particle filter. The particle detector apparatus includes a light source, an optical focusing device, a spatially resolving light detector and an evaluation device. The light source emits source light onto the surface. The optical focusing device focuses image light that is emitted from the surface in response to the source light onto the spatially resolving light detector. The spatially resolving light detector includes light sensors that measure brightness values based on the image light, such that the light detector produces image data based on the brightness values delivered by the light sensors. The evaluation device then ascertains the number of particles based on the image data.

摘要： A method and its possible embodiments are presented for collecting airborne biological and non-biological agents and concentrating them into small amounts of liquid. Airborne particles are drawn into the sampler and by the action of an electrostatic field are deposited on the collection electrode covered with superhydrophobic substance (surface contact angle >150°). At the end of the sampling period a small liquid droplet (5-60 μL) is injected at the top of the sampling chamber. Since the sampler is positioned at an angle to the horizontal, the droplet rolls-off of collection electrode's surface under the force of gravity and removes the deposited particles. The droplet is then collected by a liquid capture system. The particles concentrated in such small amounts of liquid facilitate sample analysis by various techniques. The suggested sampler's embodiments achieve sample concentration rates higher than 1×106/min which will allow detection of very low particle concentrations.
摘要翻译：提出了一种方法及其可能的实施方案用于收集空气传播的生物和非生物试剂并将其浓缩成少量的液体。空气中的颗粒被吸入采样器中，并且静电场的作用沉积在覆盖有超疏水物质（表面接触角> 150°）的收集电极上。在采样周期结束时，在采样室的顶部注入小液滴（5-60μL）。由于取样器与水平面成一定角度，所以液滴在重力作用下滚落收集电极的表面，并去除沉积的颗粒。然后通过液体捕获系统收集液滴。浓缩在这种少量液体中的颗粒有助于通过各种技术进行样品分析。建议的采样器的实施例实现高于1×106 / min的样品浓度，这将允许检测非常低的颗粒浓度。

摘要： Method and assembly for determining the presence of soot particles in a gas stream such as in the air. To prevent the disturbing effect of salts and the like that may be deposited on soot particles, it is proposed to introduce the soot particles into water as a suspension. The salts concerned dissolve in the water and have no effect when determining the change in optical properties resulting from the presence of the soot particles. This determination comprises in particular a light transmittance measurement. The presence of the soot particles can be determined after the gas stream is first passed through a filter, as a result of which a particle size distribution can be determined.Suspension of the soot particles can be achieved by subjecting these to a stream of steam, whereby the steam condenses on the soot particles and then causes these to precipitate out of the gas. The various processes can be expedited by using a cyclone.

摘要： An aerosol-into-liquid collector (ALC) for collecting gas-borne particles from a large volume of gas such as air into a small volume of liquid is described. The ALC uses a linear quadrupole to concentrate particles flowing in a gas and to help direct these concentrated particles toward a small volume of collection liquid so that these particles tend to combine with a small volume of collection liquid that can then be drawn from the ACL for further analysis. The particles in the gas are typically given a charge that is opposite to that of the charge imparted to the volume of collection liquid so that electrostatic forces help draw particles from the flowing gas into the small volume of liquid. The linear quadrupole focuses toward it axis particles that have the charge, mass and mobility to be stable in the linear quadrupole.

摘要： A gas separation system suited for extraction of gas dissolved in pressurized fluid. The system includes a semi-permeable membrane in the form of tubing having an inner core volume with an internal support present within the inner core volume. The internal support provides multiple cylindrical supporting surfaces which are presented to the inside tubing wall surface to prevent collapse of the tubing wall against external pressure. Internal supports may include a coil of spring-like configuration fitted coaxially within the tubing; or multiple filaments that form a longitudinal bundle within the core of the tubing. The response time of the system may be enhanced by the presence of an outer tubular conduit surrounding the semi-permeable membrane tubing and providing a flow path for the external fluid to increase the rate of diffusion of dissolved gases through the semi-permeable membrane. Gas pressures may be a sensed, both total and partial, as well as the identity of respective sampled gases.

摘要： An apparatus for the collection of airborne microorganisms and gaseous substances includes an air intake mechanism capable of drawing in an air sample. The air sample is thereupon percolated through a reservoir containing a liquid means as the air is passed through an air intake chamber and through the reservoir. As the air sample is passed therethrough, airborne pathogens including microorganisms or gaseous substances disposed within the air sample will become suspended within the liquid means. The air sample is thereupon exhausted through the apparatus through an exhaust chamber. A sampling port adjacent to the reservoir allows for the extraction of a sample of liquid means so the sample may be tested to determine the presence of any airborne pathogens including microorganisms or gaseous substances by means of its DNA or genetic fingerprint or by gas mass spectrometry.

The denuder includes a housing including an internal cavity, a sample gas inlet fluidly coupled with a sample gas source, a denuder liquid inlet fluidly coupled with a denuder liquid source, a barrier sheet extending across the internal cavity and separating the internal cavity into a liquid reservoir and a gas flow-through channel fluidly coupled with and downstream of the sample gas inlet, and a denuder liquid disposed in the liquid reservoir and permeating the barrier sheet to coat the gas-channel surface of the barrier sheet thereby allowing the denuder liquid on the gas-channel surface to contact the sample gas flowing within the gas flow-through channel and allowing the analyte to diffuse through the barrier sheet into the liquid reservoir.
