摘要： A particle distributor assembly 10 for distributing the particles of a drill sample is described. The distributor assembly comprises a stationary inlet tube 14 through which particles enter the distributor assembly 10, and a rotatable distributor head 16. The rotatable distributor head 16 has an upwardly directed inlet 18 offset from a central axis of rotation of the distributor head 16 and a transversely directed outlet 22 wherein, in use, when the distributor head 16 is rotated at high speed particles entering the distributor head inlet are accelerated outwardly in a radial direction through the distributor head outlet. The particle distributor assembly 10 also has a distributor nozzle 24 having an inlet 26 and an outlet 28, the nozzle inlet 26 being aligned with the stationary inlet tube and the nozzle outlet 28 being aligned with the distributor head inlet. The distributor nozzle 24 is supported between the inlet tube 14 and the distributor head 16 in such a manner that it is constrained from rotating while the nozzle outlet 28 is able to oscillate in a circular motion with the distributor head inlet 18. In use, the oscillating motion of the nozzle outlet 28 helps to promote particle flow and produce a more representative distribution of particles exiting from the distributor head outlet 22.

摘要： An inertial filter to be disposed in the air flow path of a stream of air containing nanoparticles includes plural particle classifying sheets having plural mesh-like holes are disposed in the air flow path. The plural particle classifying sheets are stacked on each other in a manner that a part of at least one of the particle classifying sheets overlaps with the other particle classifying sheet. The inertial filter can adjust a classification diameter by adjusting a shadow area ratio on a projection view obtained by virtually projecting the plural particle classifying sheets from a downstream side to an upstream side of the air flow path.

摘要： The present invention provides a method and an apparatus for determining separation efficiency of a cyclone separator. The method comprises: collecting solid particles separated by a cyclone separator; performing a particle size analysis for the collected solid particles; calculating feature parameters of the collected solid particles according to a result of the particle size analysis, wherein the feature parameters are values representing particle size and particle size uniformity of the solid particles; and determining a separation efficiency corresponding to the feature parameters of the collected solid particles as a separation efficiency of the cyclone separator, according to a predetermined correspondence between feature parameter and separation efficiency. The present invention avoids the difficulty in directly measuring the material concentrations at the inlet and the outlet of the cyclone separator and has a small interference with the apparatus. In addition, the test requires a simple operation and has a good repeatability.

摘要： Analyzing a hydrocarbon-containing fluid includes providing a hydrocarbon-containing fluid to a separation system including a cyclone separator, and separating the hydrocarbon-containing fluid into a gas phase sample and a liquid phase sample. The liquid phase sample is separated into an aqueous sample and a non-aqueous sample. The volume of the gas phase sample and of the non-aqueous sample are assessed, and the ratio of the volume of the non-aqueous sample to the volume of the gas phase sample yields the condensate-gas ratio.

摘要： Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.

摘要： A portable nanoparticle sampler for collecting respirable particulate matters and nanoparticles is composed of a tangential flow cyclone, a multi-microorifice impactor and a filter cassette. The tangential flow cyclone can remove the microparticles with cutoff aerodynamic diameter (dpa) larger than 4 μm and guide the airflow to the multi-microorifice impactor located below the cyclone. The multi-microorifice impactor includes a multi-orifice nozzle and a rotary impaction plate for enabling the microparticles with dpa from 100 nm to 4 μm to be uniformly collected on a silicone-oil-coated impaction substrate. The remnant microparticles with dpa smaller than 100 nm are collected by the filter cassette. Therefore, compared with the prior art, the portable nanoparticle sampler is characterized by low pressure loss and accurate microparticle sizing to meet the requirement of nanoparticle sampling at workplaces.
