  • Whatman - Quartz fiber filters

    GE Healthcare Life Sciences offers QM-A and QM-H types of quartz filters. The low level of alkaline earth metals virtually eliminates 'artifact' products of sulfates and nitrates (from SO2 and NO2). QM-H is a pure quartz fiber filter with low heavy-metal content. 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 500ÂșC), and for PM10 a

    Whatman - QM-A Quartz microfiber filter

    High-purity quartz (SiO2) microfiber 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. Because of the low level of alkaline earth metals, 'artifact' products of sulfates and nitrates (from SO2 and NO2) are virtually eliminated. QM-A, sequentially numbered according to EPA standards, is suitable for most applications.
