Emerging Contaminants Analytical Resource


The ECAR leverages ALEC, an existing core analytical facility at UA, which is dedicated to providing the analytical capabilities and technical expertise required to detect and quantify small contaminant molecules (organic and inorganic) in complex matrices including biological fluids, tissue, water, air, soil, sediment, and biomass. Laboratory instrumentation is maintained by a combination of funding sources including NSF, NIH, DoE, and the State of Arizona. Principal methods involve off-line or on-line separations followed by mass spectrometric detection. Since 2009, ALEC has served as the UA Superfund Research Program Hazard Identification Core (UA-SRP-HIC), and in addition, performed analyses in support of multiple SWEHSC publications.


PROJECT CONSULT : The IHS Pathway to Project Support

The ECAR has developed a structured approach to providing assistance for projects receiving subsidized support, to ensure that the best delivery of support results in successful research outcomes.

The ECAR is led by Jon Chorover, PhD, and includes two full-time research scientists dedicated to assisting SWEHSC researchers to access the full range of analytical capabilities. Leif Abrell, PhD, oversees organic mass spectrometric analyses (LC-MS/MS, GC-MS/MS, LC-QToF-MS), whereas Mary Kay Amistadi, MS, is in charge of inorganic mass spectrometry (ICP-MS, LC-ICP-MS). These individuals train frequent users or perform analyses on a cost-recovery basis.
