MTL Weighing Chamber

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.

RDI Sampling and Analysis

Rotating Drum Impactor (RDI) samplers collect size-segregated samples with variable time resolution. Multiple non-destructive analyses of RDI samples are available, including synchrotron-induced X-Ray Fluorescence (SXRF) that provides quantitative elemental data of elements.

Primary contacts: Yongjing Zhao and Nicholas Spada.

HIPS

Since 1994, the researchers at Air Quality Research Center are measuring the light absorption by particles collected on filters for IMPROVE network. This measurement has been conducted on developed in house instrument called HIPS (Hybrid Integrating Plate and Sphere system) operating at a single wavelength using red light of 633 nm from a He(Ne) laser. 

Gravimetric Mass Sampling

Our laboratory is equipped with two Mettler Toledo XP-6 microbalances and one Mettler Toledo XP2U ultrabalance. The maximum weight capacity of the XP-6 is 6 g, although most of our filters weigh around 50 mg. The quoted readability of XP-6 balance is 0.001 mg. The Gravimetric Mass Sampling is completed in the Sample Handling Lab by AQRC staff. Samples are measured during the pre-processing and post-processing where they are then sent for analysis.
