Filtration for Air Monitoring - Brochure

Two of the most significant fractions of suspended particulate matter are the respirable fraction (< 2.5 μm) and the inhalable fraction (< 10 μm). Two important tests performed in air monitoring of particulate matter, PM 2.5 and PM 10, pertain to these two fractions. Whatman™ glass fiber filters from Cytiva are recommended for gravimetric determination of airborne particulates, such as PM 10, stack sampling, and absorption methods of air pollution monitoring. In the analysis of collected particulate matter, care should be given to the choice of the filter medium used. The filter medium should give little or no background level for the elements and/or compounds being analyzed and should cause minimal interference in the determination.
