PM10 Size Selective Inlet for Hi-Vol Air Sampler SKU: TE-6001

The TE-6001 PM10 Size Selective Inlet is a precision-engineered component designed for federal reference method (FRM) high volume air samplers that collect ambient particulate matter with an aerodynamic diameter of 10µm or less. This specially shaped inlet draws ambient air at a constant flow rate where suspended particulate matter is inertially separated into size fractions within the PM10 size range.

Operating Principle

As particulates travel through the size selective inlet, larger particles are trapped inside the inlet while smaller PM10 particulates continue through and are collected on the 8" x 10" quartz filter paper. The particle size discrimination characteristics (sampling effectiveness and 50 percent cutpoint) of this inlet are prescribed as performance specifications in 40 CFR Part 53.

Key Specifications

• Compatible with flow rates between 36-60 ft³/min during 24-hour sampling periods
• Designed for particulate matter separation at 10 µm aerodynamic diameter cutpoint
• Constructed for continuous outdoor operation in ambient conditions

Regulatory Compliance

This inlet is designed according to guidelines outlined in 40 CFR Part 50, Appendix J and designated as a federal reference method sampler under designation number 0202-141. The method provides for measurement of PM10 mass concentration in ambient air over a 24-hour period for determining attainment and maintenance of primary and secondary national ambient air quality standards.

Compatibility

The TE-6001 inlet is compatible with Tisch Environmental high volume PM10 air samplers including mass flow controlled (MFC), volumetric flow controlled (VFC), and PLUS technology systems. Flow rate control can be achieved through mass flow controller, volumetric flow controller, or electronic flow controller technologies.

Applications

Essential for EPA-compliant ambient air quality monitoring programs, this inlet supports:

• NAAQS compliance monitoring for PM10
• State and local air quality surveillance networks
• Industrial perimeter monitoring
• Environmental impact assessments
• Research and special monitoring projects requiring PM10 size fractionation
