Aerosol filter housing

The resolution of this conundrum was in fact to provide the filter housing with separate sterilisation facilities and to design and orientate the aerosol... 

Diffusion losses of aerosol nanoparticles due to internal surface area of filter housing units and associated tubing can be quantitated by comparing aerosol particle size distributions obtained from an aerosol that follows different paths within the reactor. As shown in Figure 6.29, the solid circle data is the particle... 

Diffusion losses of aerosol nanoparticles can be quantified for empty filter housings under various conditions and with different orientations. Assessing and understanding the diffusion losses associated with filter housing interior volumes is important for the following reasons. Filtration efficiency is commonly calculated using Equation 3 below ... 

Loss Efficiency of S1O2 Aerosol Nanoparticles Through Nominally Identical Filter Housings that Do Not Contain Filter Media. 

The sampling operation involves collection of an aerosol sample that is representative of the particle size distribution and concentration of the sampled atmosphere. The efficiency of particle transport and collection operations are dependent on the particle size, sampling velocity, the geometry of the sampling apparatus and the properties of the collection medium. In the present work, a 37 mm diameter membrane filter (0.3 ym pore size) is the primary collection medium under evaluation. The filter is housed in a standard filter cassette and effects of filter-holder inlet geometry are also being investigated. 

The most popular geometry for the detection housing has been the cup-type container closed at one end with a porous filter such as fiberglass, a nonwetting cloth, or a microcore paper filter. These porous filters always ensure that aerosol radon daughters will not enter the sensitive volume of the detector, but they may not be efficient discriminators of thoron gas and water vapor.
