(for EPA PM 2.5 Reference Method, under the requirements of 40 CFR Part 50, Appendix L)

PM 2.5 PTFE membrane filters are designed for PM 2.5 ambient air monitoring. These high-purity, thin filters are sequentially numbered and come with chemically resistant polypropylene support rings.
Polypropylene support rings for robotic air sampling
Thermally stable design eliminates curling, keeps the membrane flat, and makes the filter robot-friendly
Sequentially numbered filters
Low tare mass for accurate gravimetric determinations

Robotic air sampling filter for PM 2.5 air monitoring
Ambient air monitoring requires a chemically resistant air sampling filter that can withstand environmental pollution potentially containing a variety of contaminants and can still deliver accurate results.

PM2.5 PTFE membrane filters also feature a thermally stable design, making them ideal for ambient air monitoring. These membranes come in a polypropylene support designed for use in robotic air sampling.

PM 2.5 air monitoring filter conformance
These air sampling filters comform to the PTFE Filters for EPA PM 2.5 Reference Method, under the requirements of 40 CFR Part 50, Appendix L.
