Abstract

Liquid chromatography - inductively coupled plasma - mass spectrometry (LC-ICP-MS) and liquid chromatography - mass spectrometry (LC-MS) are very powerful tools for looking at organo- metal speciation in the environmental and biological systems, but both have their limitations. LC-ICP-MS has inability to give structural information concerning unknown eluted peaks while LC-MS has a requirement for correct ionisation conditions and inability to detect inorganic ions. By coupling the two techniques complete characterisation of organo-metal compounds/complexes can be determined on a single analytical run. We already have an LC-MS and request an ICP-MS to couple to it. The LC-MS-ICP-MS would be used for the following applications: (I) Arsenic metabolites in biological tissues and soils. (II and III) Fate and biotransformation of antimony, tellurium and thallium. (IV) Dynamics of species- dependant Se metabolism in mammals. (V) Role of thermophilic microbes in the precipitation of semi-metals (and other metals) in subaerial hot springs.
