Most industrial hygiene sampling for particulates is finished employing a filter that is definitely 37 millimeters (mm) in diameter. One exception is asbestos, which utilizes a twenty five mm diameter filter. The 2 most commonly applied filters are made of polyvinyl chloride that has a 5-micron pore sizing and combined cellulose ester by using a 0.8-micron pore dimensions. The filters appear like very slim plastic discs With all the consistency of rigid tissue paper because the filters are so delicate. These are placed in a little plastic cassette to aid managing.
