Axiva - Filter for PM2_5 Air Monitoring A high-purity, thin PTFE membrane in a sequentially numbered chemically resistant polypropylene support ring for PM 2.5 ambient air monitoring. These membranes have low tare mass for accurate gravimetric determinations. The thermally stable design eliminates curling, keeps the membrane flat The PM 2.5 PTFE membranes are manufactured under clean room conditions. These chemically resistant, low chemical background filters permit sensitive, interference free determinations.
Technical Specifications: PTFE Filters for Use in US EPA PM 2.5 Ambient Air Monitoring Property Value PTFE filter media PTFE Filter thickness 40µm Filter diameter 46.2mm 2µm Fitler pore size Support ring media Polypropylene Total support ring thickness 0.38 mm approx
