Whatman QM-A Quartz Microfiber Air Sampling Filters

GE's 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. Temperature resistant up to 800°C and binder-free. Because of the low level of alkaline earth metals, artifact products of sulfates and nitrates (from SO2 and NO2) are virtually eliminated. High-purity quartz microfiber filters are therefore applicable for particulate monitoring and heavy metal analysis. QM-A quartz microfiber filters from GE come in a wide range of circle diameters, as well as 25-piece sheets. QM-A sheets (Cat. No. 889-14536, 889-14542, and 889-14614) are sequentially numbered according to U.S. Environmental Protection Agency (EPA) standards and are suitable for most applications.
