These high-purity quartz microfiber filters are used in many air sampling filter applications, including sampling of acidic gases, stacks, flues, and aerosols. Filters are suitable for PM-10 sampling and analysis.
High-purity quartz (SiO2 ) microfibre filters are used for air sampling in acidic gases, stacks, flues and aerosols, particularly at high temperatures up to 500°C and in PM-10 testing.
Due to the low level of alkaline earth metals,€˜artifact€™ products of sulphates and nitrates (from SO2 and NO2) are virtually eliminated. The high purity of the filters makes them suitable for particulate monitoring and heavy metal analysis.
QM-A quartz microfiber filters come in a wide range of circle diameters, as well as in sheets. The sequentially numbered sheets are made according to the US EPA standards and are suitable for most applications.
- Temperature resistant up to 500°C
- Binder-free
- High loading capacity
- Fast flow rates (air flow rate 6.4 s/100ml/in2)
