Feature

●Dimensions: 8 x 10 inch sheet
●High purity quartz (SiO2) microfibre filter is 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


Description

Whatman high purity quartz (SiO2) microfibre 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. Dimensions: 8 x 10 inch Sheet. 25/Pack. Whatman #: 1851-865.
