Quartz Filter - Grade QM-A: 2.2 µm
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.
We would appreciate your feedback.
