Key Quartz Microfiber Membrane Characteristics

Binderless quartz construction eliminates organic contamination and maintains chemical purity at extreme temperatures
99.999% high purity SiO2 with ultra-low metals content delivers contamination-free results for trace analytical determinations
Exceptional thermal stability withstands continuous operation to 1000°C without degradation or dimensional change
2.2µm retention efficiency captures fine particulates while optimizing airflow for high-volume ambient air sampling
Hydrophobic surface chemistry resists moisture interference during stack gas monitoring and acidic aerosol collection

Key Construction Characteristics

Fine porosity microfiber matrix achieves 99.999% efficiency for 2.20µm particles in critical air filtration protocols
Robust tensile strength of 215g/15mm (ASTM D828)² ensures handling integrity during filter installation and changeout procedures
Minimal loss on ignition below 6% validates chemical purity for gravimetric analysis and elemental determinations
Standard 82.6mm diameter accommodates high-volume sampling equipment and universal filter holder configurations
Uniform screen and felt sides with consistent MD/CD density demonstrates excellent lot-to-lot reproducibility for analytical consistency

LE-Q8260-2 filters achieve outstanding 1.1-1.35 m³/min flow rates with resistance of only 95mmH2O at 10.5 ft/min, accelerating your sampling cycles during extended monitoring campaigns. Superior chemical resistance to all acidic gases except hydrofluoric acid maximizes analytical flexibility when monitoring corrosive emissions and industrial stack effluents. EPA PM10 compliance¹ transforms these filters into validated reference-grade media, providing performance assurance for your critical air pollution monitoring, flame emission spectrometry, and atomic absorption applications demanding both extreme temperature tolerance and certified analytical precision.
