OMICRON PTFE Membrane Filters are engineered specifically for Particulate Matter (PM2.5) Air Monitoring as per environmental guidelines. These filters are ideal for gravimetric analysis and chemical characterization of airborne particulate matter collected from ambient air sampling. The filters consist of a hydrophobic polytetrafluoroethylene (PTFE) membrane laminated on rigid polypropylene support ring — ensuring excellent particle retention, dimensional stability, chemical inertness, and compatibility with automated filter handling systems.
- Low Background Weight Variability: Ideal for gravimetric weighing | Chemically Inert: Resistant to acids, bases, and organic solvents
- Hydrophobic PTFE Membrane: Prevents water absorption and supports aerosol sampling | Consistent Filtration Efficiency: Excellent PM2.5 retention with minimal pressure drop
- Thermal Stability: Operates up to 260° C — ideal for both field and lab use | Low Metal Content: Suitable for trace element and metal analysis
- Filter Type: PTFE Membrane with PP Support | Application: PM 2.5 Air Monitoring | Membrane Material: Polytetrafluoroethylene (PTFE) | Support Material: Polypropylene ring
- Filter Diameter: 46.2 mm (standard) | Effective Filtration Area: ~12.5 cm² | Pore Size: 2.0µm nominal | Collection efficiency: >99.7% with 0.3µm particle size | Air Flow Resistance: <1.5 mbar at 30 L/min
- Support Ring Width: 3.68 (+0.00 mm, -0.50 mm) | Support Ring Thickness: 0.38 ± 0.04 mm | Tensile Strength: >10 MPa | Max Operating Temp.: Up to 260° C | Temperature Weight Loss Stability: ≤ 20 µg | Metal Impurities: <0.01 ppm (for ICP trace metal analysis) | Storage Conditions: Room temperature, desiccated, clean environment
- Ambient Air monitoring for PM2.5 collection | Gravimetric analysis of suspended particulate matter | Elemental and chemical composition studies (eg. ICP-MS, XRF, Ion Chromatography) | Suitable for use in Hi-Vol and Low-Vol Samplers
- Sequential Alphanumeric for easy traceability + Scannable Data Matrix Code for convenience
