Glass microfiber and Quartz microfibre filters are recommended for the analysis of atmospheric pollution and for particle determination even at high temperatures. They are resistant to aggressive chemicals with the exception of hydrofluoric acid.
Due to their pureness, stability, high flow rate and the high filtration performance this filter materials are recommended for the ambient air monitoring such as the determination of suspended particulate matter (SPM), TSP (Total Suspended Particular matter), PM10 and lead (Pb).
Target Application:
Monitoring and survey of the presence of pollutants in the air at different measuring points.
