说明

一般說明

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.
