The AQRC Sample Handling Lab serving IMPROVE network has been equipped with a benchtop MTL environmentally controlled weighing chamber that provides compliant environment (Quality Assurance Guidance Document 2.12) for ambient air quality research. Air velocities, temperature, dew point, and airborne particle counts are controlled and below their regulatory thresholds.

Rotating Drum Impactor (RDI) samplers collect size-segregated aerosols on 8 stages with 0.4 – 4.8 hour time resolution.  Analysis of RDI samples using X-Ray Fluorescence (XRF) technology provides quantitative elemental data of 28 elements.
