Key Quartz Microfiber Membrane Characteristics

Binderless quartz construction eliminates organic contamination and maintains purity at extreme temperatures
99.999% high purity SiO₂ with ultra-low metals delivers contamination-free results for critical trace analysis
Exceptional thermal stability withstands continuous operation to 1000°C without degradation or dimensional change
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

Key Construction Characteristics

Fine porosity microfiber matrix achieves 99.999% efficiency for 2.20µm particles in air filtration protocols
Robust tensile strength of 215g/15mm (ASTM D828)¹ ensures handling integrity during filter installation and changeout
Minimal loss on ignition below 6% validates chemical purity for gravimetric analysis and elemental determinations
Standard 110mm diameter accommodates EPA Method PM10² sampling equipment and universal filter holder configurations
Uniform screen and felt sides with consistent density MD/CD demonstrates excellent lot-to-lot reproducibility

LE-Q1100 filters achieve exceptional 1.1-1.35 m³/min flow rates optimized for ambient air monitoring, accelerating your sampling cycles even 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 compliance² transforms these filters into validated reference-grade media, providing performance assurance for your critical environmental monitoring and atomic absorption spectroscopy applications demanding both extreme temperature tolerance and certified analytical accuracy.
