Quartz Microfiber Filter, Grade QFH, W/O Binder, Plain Discs, 47 mm Diameter, 50 pcs/pack
Article no.: QFH047
Quartz fiber filters are made of very pure quartz fibers with no binders and glass fibers. The pure quartz composition prevents the filters from reacting with acidic gases, unlike glass fiber filters that can react and cause false readings. This makes quartz filters well suited for measuring heavy metal concentrations and small amounts of particles.
Quartz fiber filters are used for air sampling in acidic gases (except HF), stacks, flues and aerosols, particularly at high temperatures and in PM-10 testing as well as where absolute purity of the filter medium is required.
Standard Features
Filters made of pure quartz microfiber (SiO₂), free of binding elements or additives
Ideally suited for trace analysis owing to extremely low metals content
Excellent stability against chemical solvents, alkalis and acids, even in extreme conditions involving acidic gases (HCl, SO₂, SO₃, H₂SO₄, NO and NO₃); except hydrofluoric acid (HF)
Usable in temperatures of up to 1000 ºC
Applications
+ Determination of suspended particles (SPM and TSP) in ambient air acc. to the directive of the US EPA (Environmental Protection Agency) and the EN 23210
+ Applications that require a maximum filter purity with a low metal content and no carbon traces
+ Filtration and analysis of both acid and alkaline gases and of solvents
+ Emission: pollution controls performed on air within industrial stacks, smoke ducts and aerosols
