PM 2.5 Membrane Filters
◆ Description PM 2.5 PTFE Membrane is a high-purity, thin membrane for PM 2.5 ambient air monitoring. Each membrane has low chemical background and a chemically resistant polypropylene support ring for added strength. Each piece has a printed number on the support ring. The low tare mass allows for accurate gravimetric determinations. No glues or adhesives are used in making of the membranes. Its design eliminates curling, keeping the membrane flat and allowing for automation use. Meets EPA reference method for PM 2.5, under the requirements of 40 CFR Part 50, Appendix L. PM2.5 Membrane Specifications Model Number M-PTFESR047N200O Material Hydrophobic PTFE Filter Thickness 55μm Filter Diameter 46.2mm Filter Pore Size 2.0μm Support Ring Media Polypropylene Support Ring Thickness 0.45mm Support Ring Width 3.7mm Particle Retention (0.3μm) 99.8%
PVC Membrane Filters
Model No.: M-PVC037N500I Hydrophilic PVC Membrane Membrane Size: 37mm Pore Size: 5.0µm Package: 100pcs/pk Ideal for use in air monitoring for metals, silica, and dust. Its low moisture pickup makes it ideal for use in gravimetric analysis. ◆ Features: Excellent membrane choice for sampling airborne metals, silica, and dust. Pure homopolymer PVC. Inherently low ash membrane ideally suited for multiple NIOSH analytical methods. Assured gravimetric stability. Low moisture pick-up and low tare weight. Low ash. Provides interference-free silica determinations. Meets NIOSH and OSHA requirements.
