TSP/PM10/PM2.5 - Filters

High-purity quartz microfiber filters are used in many air sampling filter applications, including sampling of acidic gases, stacks, flues, and aerosols. Filters are suitable for PM-10 sampling and analysis.

• Temperature resistant up to 500°C
  

• Binder-free
  

• High loading capacity
  

• Fast flow rates (air flow rate 6.4 s/100 ml/in2)

EPM 2000 air filters are used in high-volume PM-10 sampling equipment. Manufactured from 100% pure borosilicate glass, they enable detailed chemical analysis of trace pollutants with minimal interference.

• Air retention efficiency of 99.95 percent of 0.3 µm size particulates

• Selected by the U.S. Environmental Protection Agency (EPA) for use in a nationwide network of HiVol air samplers

• Manufactured according to ISO9001:2008 QMS standards
  

• Available in both sheet and circle design
  

• Sheets are individually numbered to facilitate

• identification
  

• Binder-free

Grade 41 environmental pollution papers are among the fastest filter papers in the Whatman ashless range. This gravimetric filter is well suited for quantitative analysis of soil and air.

• Extremely low ash content (0.007% ash maximum)
  

• 20 µm nominal particle retention rating
  

• Fast filtration speed (Herzberg 54 s)
  

• Commonly used for routine air pollution analysis and soil pollution analysis

PM2.5 PTFE Filters
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
