Method and device for aerosol size-selective sampling |
摘要 |
An aerosol size-selective sampling device is composed of pre-filter, a base housing, and a collector. The device is intended to take an aerosol sample from a given atmospheric air. The pre-filter is composed of two or more porous filtration materials arranged in one end of the base housing in a parallel manner for allowing the atmospheric air to pass therethrough in a parallel and diverting pattern before the atmospheric air is allowed to pass in a converging manner through the collector which is located in another end of the base housing. The pre-filter is able to attain a desired penetration rate profile as a function of an aerodynamic diameter of aerosol contained in the atmospheric air within a predetermined range of aerodynamic diameter. <IMAGE> |
