Highpurity quartz microfibre filters are mainly used for the low particle content in air pollution monitoring especially when a very pure filter is required or when the physical or chemical conditions of the gases are extreme. Our quartz fibres have excellent filtration properties and outstanding weight and dimension stability. They can be used for air sampling and gravimetric calculations ...
Glass Fibre Filters (GFA) These low cost filters are commonly referred to as depth filters. They are ideal for general gravimetric air sampling and analysis. Suitable when no other analysis than weighing is required. Binder and additive free. Available unweighed and preweighed. See more. Mixed Cellulose Ester (MCE) Developed from a mixture of cellulose acetate and cellulose nitrate, MCE ...

Quartz Fiber Filters (Type AQFA) Made of quartz fibers with no glass fibers or binders. Millipore's pure quartz manufacturing process involves a heat treatment step to improve the composition and prevent 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 ...

Heatshrunk quartz fiber filters were tested at temperatures up to 510°C (950°F) with a polydisperse NaCl aerosol of mass median diameter (mmd) at velocities (V) of 15 cm/sec to 30 cm/sec. Average penetrations ranged from % to % with no consistent trend with respect to temperature. Individual readings of NaCl penetration varied as much as + 50% about the mean during .

Glass and Quartz Fiber Filters For analytical or gravimetric studies "OROSILICATE'LASSIBERILTERS create a biologically inert filter matrix that is resistant to both chemicals and pH extremes. Use as prefilters to extend membrane life, for water/air pollution analysis, or liquid clarifiion. Filters without binder withstand up to 932°F (500°C); filters with binder withstand .
Filters without binder withstand up to 932°F (500°C); filters with binder withstand up to 250°F (120°C). Grades GC90, GS25, and DP70 with binder offer higher wet strength and lower fiber release. Quartz fiber filters have very low trace metal content and can withstand up to 1832°F (1000°C). Choose quartz fiber filters to sample acidic gases at high temperatures or for air pollution analysis.
