| General description: | 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. • Grade: QM-A • Description: Quartz • Particle Retention in Liquid (μm): 2.2 • Air Flow (s/100 mL/in²): 6.4 • Typical Thickness (μm): 450 • Basis Weight (g/m²): 85 |
