Quartz Filters

DSC offers QM-A quartz filters. The low level of alkaline earth metals virtually eliminates "artifact" products of sulfates and nitrates (from SO2 and NO2). High-purity quartz (SiO2) microfiber filters are mainly used in air pollution monitoring. They can be used for air sampling in acidic gases, stacks, flues and aerosols, particularly at high temperatures (up to 500ºC), and for PM10 and PM2.5 air sampling testing. Quartz filters are suitable for critical analyses and trace level determinations, atomic absorption spectroscopy, and flame emission spectrometry.
