PM2.5 AIR MONITORING MEMBRANE FILTERS
Precision Filtration for Continuous Air Quality Monitoring
Description
PM2.5 PTFE membrane filtration devices are designed for PM2.5 ambient air testing during continuous monitoring. These high-purity, thin PTFE membrane filters are sequentially numbered and come with chemically resistant polypropylene support rings for reliable and consistent performance.
Features & Benefits
• Polypropylene support rings for robotic air sampling and monitoring • Thermally stable design eliminates curling, keeps the membrane material flat, and makes the filter robot-friendly • Sequentially numbered filtration devices for easy tracking and quality control • Low tare mass for accurate gravimetric analysis and determinations • High-purity PTFE membrane ensures minimal background interference • Chemically resistant support rings for long-term durability • Robot-compatible design for automated sampling systems
Applications
• PM2.5 ambient air monitoring • Continuous air quality assessment • Environmental compliance monitoring • Particulate matter gravimetric analysis • Automated air sampling systems • Research and regulatory testing
