Trace Element Speciation
The effect of trace elements in living systems, food and the environment, depends on the chemical form in which the element enters the system and the final form in which it is present. The form, or species, governs its biogeochemical characteristics. The production of Certified Reference Materials (CRMs) for speciated arsenic, tin and mercury content has been facilitated as a result of the Chemical Metrology group's research activities targeting novel sample preparation approaches, synthesis of isotope enriched species specific calibration standards, coupled instrumental techniques, multiple extraction methodologies and novel solid phase microextraction procedures.
