0

GE’s Whatman PM2.5 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 from GE Healthcare’s Life Sciences business 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.
