A state of the art trace metal clean room facility containing 4 variations of mass
spectrometer is being constructed in the Centre for Environmental and Information
Technology. The mass spectrometer is the most widely accepted detector of majorand
trace-elements for environmental analysis. We will be using mass spectrometry
for geochemical and isotope analyses of groundwater collected from metalcontaminated
mining, power generation and industrial sites, and also from field and
laboratory investigations of groundwater remediation.
Methods based on mass spectrometry are among the most powerful, sensitive, and
reliable available for water science research. Inductively coupled plasma mass
spectrometry (ICP-MS) is an analytical technique which requires the sample (usually
liquid) to be introduced to a high temperature plasma (a gas consisting of ions,
generated by radio frequency magnetic fields), commonly argon, which dissociates
molecules and ionizes atoms. The ions are passed into vacuum where a lens focuses
the ion beam into a mass spectrometer. Here, the ions are sorted by mass and
detected.See Poster
