Inorganic Geochemistry Laboratory
Analytical instrumentation in the LLO Inorganic Geochemistry Laboratory includes a Perkin-Elmer Elan-6000 inductively coupled plasma mass spectrometer (ICP-MS), a Dionex ion chromatograph (IC) and a Jobin Yvon Ultima-C inductively coupled plasma Emission Spectrometer (ICP-ES). The laboratory is also equipped with a microwave digestion system for rapid dissolution of sediment and material. These instruments are utilized for studies of distributions of major and trace elements to examine natural geochemical processes in large lakes, as well as the effects of human perturbation on such systems.
