Details:
Cytiva’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
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 Cytiva 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 ConformanceThese 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.

Applications
-
Air Monitoring for Laboratories - Monitoring and Testing - Laboratory Equipment
Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.Common air monitoring applications include:Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.Asbestos sampling and analysis
