Analytical Services

Since the late 1970s, the Air Quality Research Lab (AQRC) has been a leader in the characterization and analysis of the microscopic airborne particles that cause regional haze, the kind of air pollution that impairs visibility over widespread areas. Over the years, a major thrust of our research has been the development and refining of techniques and equipment necessary for the analytical component of this work. We are now pleased to offer our analytical expertise and advanced equipment to the larger research community. To learn more about these services or should you wish to place an order with us, contact Principal Investigator Nicole Hyslop or the method expert listed for each technique.

RDI sampler and XRF analysis

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.

TOA Carbon

The AQRC Quartz Carbon Lab is equipped with the top-notch OCEC instruments for Thermal/Optical Analysis (TOA). Our scientists and technicians can analyze particulate matters collected on quartz-fiber filters for organic carbon, elemental carbon, carbonate carbon, and total carbon using a variety of applications. For questions on ordering analytical services contact Krystyna Trzepla or Nicole Hyslop.

XRF Calibration Standards & Reference Materials

The AQRC measures the concentrations of chemical elements in samples using energy dispersive X-ray fluorescence (XRF). We specialize in measuring airborne particulate matter sampled on filters but can also analyze liquid, solid or powder samples.

Our laboratory is equipped with five PANalytical Epsilon 5 XRF analyzers. Each analyzer can be programmed to use up to 15 secondary excitation targets, allowing the analysis to be customized to provide optimal sensitivity for the elements of interest with comprehensive coverage of the periodic table.
