The Trace Element Analysis (TEA) laboratory specializes in low-level trace metal analysis and speciation in environmental and biological samples. We use inductively coupled plasma mass spectrometry (ICP-MS) for metals analysis and several “hyphenated” techniques that couple instruments together for speciation analyses of water, soil and biological tissue samples.

The TEA Core is supported by Dartmouth’s Superfund Research Program, Sources and Protracted Effects of Early Life Exposure to Arsenic and Mercury and  provides analytical support and method development for all the Superfund researchers.  The Core also supports the Children’s Environmental Health and Disease Prevention Research Center at Dartmouth and other Dartmouth researchers.  We can also work with other academic institutions after consultation with the Core Director.

The TEA Core specializes in:

  • Low level trace element analysis in biological and environmental samples
  • Arsenic speciation in soils, food, waters and urine
  • Mercury speciation in waters, soils, sediment and biological tissues
  • Laser ablation of biological tissues
