Analytical & Archaeological Chemistry

Our laboratory uses analytical chemistry to aid in archaeological studies.  Research is currently focused upon radiocarbon dating methodology and residue analysis using GC/MS. 

In our radiocarbon dating work, we utilize the properties of oxygen plasmas, electricaly excited oxygen gas ignited with a radio frequency generator, to collect carbon from rock paintings and other archaeological materials for accelerator mass spectrometry 14C measurement.
