Whatman(R) QM-A quartz filters

Descrição detalhada : High-purity quartz (SiO2) microfiber filters are used for air sampling in acidic gases, stacks, flues and aerosols, particularly at high temperatures up to 500C 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 (mum): 2.2. Air Flow (s/100 mL/in²): 6.4. Typical Thickness (mum): 450. Basis Weight (g/m²): 85
