polyvinyl chloride, Teflon®, silver, and mixed cellulose esters. Filters from this class are used for sampling asbestos, minerals, PAH’s, particulates not otherwise regulated, and elements for ICP analysis.
Glass and quartz fiber filters
- Quartz filters have replaced glass in many applications. They are used in applications such as sampling for mercaptans and diesel exhaust.
Polycarbonate straight pore filters
- Because of their characteristics, these filters are good for the collection of particles to be analyzed by electron microscopy and x-ray fluorescence.
Respirable dust samplers
- The 10-mm nylon cyclone and (preferably) conductive cyclones with a 50% cut at 4 µm are used with polyvinyl chloride filters to collect various forms of silica.
Inhalable dust samplers
- The Institute of Occupational Medicine’s (IOM) sampler is used, in conjunction with a polyvinyl chloride filter, for sampling formaldehyde on dust [7].
