The GVS quartz microfiber filters are made with pure quartz microfibers and are free of binders or additives of any kind.

These filters have retention, loading and air permeability features similar to those of the glass microfiber filters. However,

since they have greater chemical resistance at high temperatures, they can be used in environments where extreme

conditions are present, replacing the glass microfiber filters in such cases.

D0QF1 Standard grade

D0QF2 Very pure filter/very low trace levels of heavy metals


Features

- High-purity quartz microfiber filters (SiO2) free of binding elements or additives

- Excellent retention levels for very fine particles

- Very high air permeability

- High temperature stability. It is very good up to 900ºC, some loss of their usual properties setting in beyond that point

- Excellent chemical stability with practically no filtermass losses through chemical reactions under extreme conditions with the presence of acid gases (HCl, SO2, SO3, H2, SO4, NO and NO3)


Applications

- Determination of suspended particles on the atmosphere

- Emissions monitoring in industrial chimneys

- Gravimetric determination in gases

- Monitoring the level of heavy metals in atmospheric pollution studies

- Incinerators

- When the temperature of emissions is higher than the temperature that the glass microfiber can beat, it is used quartz microfiber

- Analysis of acid gases

- Microplastic sample preparation and separation before chromatographic analysis
