Young Laboratory Facilities
General Capabilities
The Lab consists of a range of analytical instrumentation, mostly
purchased recently,
that together permit the analysis of nearly every pollutant of concern
at the lowest levels
currently feasible. Designed specifically to provide a clean
working location for sensitive
measurements of trace quantities, this equipment is primarily located
in room 2109 of the
new Engineering III building at UCDavis unless otherwise noted.
Major instrumentation
(click on the link to see more detailed specifications and photos)- 2002 Lachat Quick-Chem Flow Injection Analyzer (FIA)
- Two GC-MS systems, one with both EI and CI detection capabilities and dual inlets: cool on-column and split/splitless.
- A GC-ECD/FID also with dual inlets: volatiles and split/splitless for liquids. This system also has a complete and automated purge-and-trap sampler.
- An LC-MS ion trap with both ES and APCI interfaces.
- An ICP-MS.
- An Ion Chromatograph, with state-of-the-art Eluent Generation, dedicated to trace anion measurement in aqueous samples.
- A Cold Vapor Atomic Absorption spectrometer to accurate determine mercury in water at levels below the most stringent of current regulations.
- A pyrolysis GC-MS with built in autosampler.
- A gradient liquid chromatograph with automated sampling and diode array and fluorescence detectors.
- Two Supercritical Fluid Extraction Systems.
- In addition, there is a TOC analyzer, a Nitrogen Analyzer, and a GC-FID.
Technical Specifications
