Micro Quartz Fiber Filter Paper

• Binder-free
• 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 950°C and in PM-10 testing
• Because of the low level of alkaline earth metals, products of sulfates and nitrates (from SO2 and NO2) are virtually eliminated
