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)² ensures handling integrity during filter installation and changeout
Low loss on ignition below 6% validates chemical purity for gravimetric analysis and elemental determinations
Standard 25mm diameter accommodates standard filter holder configurations and sampling equipment
Autoclavable glass construction enables pre-cleaning protocols for ultra-trace metal analysis applications

LE-Q2500 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. Uniform screen and felt sides with consistent MD/CD density demonstrate excellent lot-to-lot reproducibility, providing performance assurance for your critical environmental monitoring, atomic absorption spectroscopy, and flame emission spectrometry applications demanding both extreme temperature tolerance and certified analytical accuracy.
