Quartz Filter - Grade QM-A: 2.2µm

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.
