The 2Stage cassette can only be used for Closed Face sampling. The 3Stage cassette can be used for either Closed Faced or Open Faced sampling. Openface sampling for aerosols (dust, metals, mists, etc.) provides a more evenly distributed sample collection and therefore less opportunity for sample loss due to buildup or filter damage.
PCR Sampling Guide PCR Air Samples 1. Obtain a 3piece PCR air/dustsampling cassette from EMSL. 2. Remove the upper (blue) and lower (red) plugs of the cassette. 3. Attach a vacuum pump to the cassette through the lower opening. 4. Sample as much air as desired through the upper opening. There is no upper limit to sampling time. 5.
Sampling for Dusts and Fumes. Dust is particles of solid material around 1#181;m to 1mm diameter. Larger particles are too heavy to remain airborne. Fumes are smaller than dust. They are solid particles formed by condensation from a gas and the particle size is typically lt;1#181;m.
25mm cassettes are 50% smaller than the standard 37mm cassettes. They have the same opening size as the standard 37mm cassette and therefore have the same capturing efficiency. Our clients use 25 mm cassettes for area sampling in hardtoreach areas and for personal sampling inside of
Gilian Air Sampling Media and Accessories. Effective Air Sampling requires a quality pump and the correct accessories. Accessories common to air sampling include membrane filters and cassettes, size selective sampling heads, media holders, sorbent tubes, impingers or bubblers, and sampling bags.
dust sampling cassette equipment Zefon Model Z045CC 25mm MicroVac Carpet/Dust Sampling Cassettes. Zefon MicroVac cassettes are designed for the collection of fibers and particulate from carpets and other dusty areas. They are specially
SKC offers a large range of filters and cassettes for particulate and gas/vapour air sampling. This range of sampling media is summarised in the comprehensive table, giving an overview of the properties and applications of each type of filter and cassette.
While selection of a specific cassette size/type and filter membrane should be determined by review of the NIOSH sampling guide, the following rules generally apply; All dusts, fumes and powders sampling use 37mm filter and cassette. All asbestos and fibers sampling use 25mm filter and cassette. Dust sampling use micron (pore
MicroVac Carpet/Dust Sampling Cassette The MicroVac cassettes are designed for the collection of fibers and particulate from carpets and other dusty areas. These specially designed cassettes have an inlet port angled at 45 degrees and come preloaded with .45#181; MCE filters. More Details
dust sampling cassettes, FTIR analyzers, monitoring NIOSH has developed a fieldbased respirable crystalline silica monitoring approach. The monitoring approach relies upon the collection of respirable dust on filter media inside dust sampling cassettes.

Dust samples are considered by some to relate to the history of what has been in the air. Dust samples for a direct examination may be analyzed immediately. Disadvantages. The results are dependent upon many factors that are difficult to control and may be difficult to interpret. Equipment. Dust filter cassette. Vacuum pump. Sampling Protocols
