Key Quartz Microfiber Membrane Characteristics

Binderless quartz construction eliminates organic contamination and maintains purity at extreme temperatures up to 1000°C
99.999% high purity SiO2 with ultra-low metals content delivers contamination-free results for critical trace analysis
2.2µm retention efficiency captures fine particulates while optimizing airflow in high-volume sampling applications
Hydrophobic surface chemistry resists moisture interference during ambient air and stack gas monitoring protocols
Exceptional loss on ignition below 6% validates chemical purity for gravimetric analysis and elemental determinations

Key Construction Characteristics

Fine porosity microfiber matrix achieves 99.999% efficiency for 2.20µm particles in EPA-compliant air filtration protocols
Robust tensile strength of 215g/15mm (ASTM D828)² ensures handling integrity during filter installation and changeout
Standard 125mm diameter accommodates EPA Method PM10¹ sampling equipment and universal filter holder configurations
Uniform screen and felt sides with consistent density MD/CD demonstrates excellent lot-to-lot reproducibility for analytical validation
Manufacturing with RO water filtration system maintains ultra-low background contamination for sensitive analytical applications

LE-Q1250-2 filters achieve optimized 1.1-1.35 m³/min flow rates with 95mmH2O resistance at 10.5 ft/min, accelerating your sampling cycles during extended monitoring campaigns. Outstanding chemical resistance to all acidic gases except hydrofluoric acid maximizes your 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, atomic absorption spectroscopy, and flame emission spectrometry applications demanding both extreme temperature tolerance and certified analytical accuracy.
