47mm Micro-Quartz Filters for PM10 Air Sampling, 100/pk SKU: TE-QMA-47

47mm Micro-Quartz Filters for PM10 Air Sampling, 100/pk

The TE-QMA-47 micro-quartz filters are 47mm diameter high-purity quartz microfiber filters designed for PM10 particulate sampling and other demanding air quality monitoring applications. Due to the low level of alkaline earth metals, artifact products of sulfates and nitrates (from SO&sub2; and NO&sub2;) are virtually eliminated, making these filters ideal for particulate monitoring and heavy metal analysis.

Technical Performance

These high-purity quartz microfiber filters are engineered for air sampling in acidic gases, stacks, flues and aerosols, particularly at high temperatures up to 500°C. The filters are suitable for PM-10 sampling and analysis, delivering reliable results in challenging environmental monitoring conditions. The 0.3µm DOP retention efficiency exceeds 99.995%, ensuring superior particle capture performance.

Key Specifications

• Diameter: 47mm circular filters
• Pore size: 2.2 µm
• Maximum operating temperature: 500°C
• DOP retention efficiency: >99.995% at 0.3µm
• Pack quantity: 100 filters per box
• Low alkaline earth metal content for reduced chemical interference

Applications

TE-QMA-47 filters are used in many air sampling applications, including PM-10 sampling and analysis, sampling of acidic gases, stacks, flues, and aerosols. These filters are particularly valuable for:

• High volume air sampling as specified in 40 CFR Part 50, Appendixes B (TSP) and J (PM10)
• Environmental monitoring and compliance testing
• Heavy metal analysis in particulate matter
• Organic chemical analyses such as PCBs and PAHs
• Source emission testing at elevated temperatures

Compatibility

The TE-QMA-47 filters are compatible with standard 47mm filter holders used in low-volume air samplers, personal samplers, and laboratory filtration systems. These filters work with most manufacturers' 47mm sampling equipment including Tisch Environmental, BGI, and other EPA-compliant sampling systems.

Quality Assurance

Tisch Environmental maintains EPA standards for filter quality, ensuring consistent performance for regulatory compliance monitoring. The high-purity quartz construction minimizes interference from alkaline earth metals, virtually eliminating artifact formation of sulfates and nitrates that can compromise analytical results.
