Quartz fiber filter, QFH, qualitative, round filter

Recommended filters for air pollution control and particle determination at high temperatures.

     Made from pure quartz microfibers (SiO2), without binders or additives
     Ideal for trace analysis due to extremely low metal content
     Determination of suspended solids (SPM and TSP) in ambient air in accordance with the relevant specifications of the US EPA (Environmental Protection Agency) and EN 23210
     Excellent absorption of very fine particles thanks to the adsorption mechanism of the quartz fibers
     Chemical stability: excellent stability with almost no loss of filter material due to chemical reactions, even under extreme conditions with acidic gases (HCl, SO2, SO3, H2SO4, NO and NO3)
     Excellent resistance to chemical solvents: bases, acids (except hydrofluoric acid) and alkaline substances
     Stability at high temperatures: higher resistance than glass microfiber; up to 1000°C
