Geochemistry Laboratories are used for graduate coursework and research.
Analyses of elemental and isotopic compositions in water, soil, sediments and biological samples are done in these laboratories. The laboratories are equipped with various instruments including: P-E Optima 5300 D ICP-OES (S. Pekar/G. Hemming) for multi-elements analysis, JV Horiba FluoroMax-3 Fluorescence spectrometer for humic substances analysis.
The laboratory also houses various field equipment for on site water quality measurements, dissolved oxygen meters, pH/Eh meters, conductivity meters, and a digital alkalinity titrator. The laboratories are also in the process of housing two instruments: Costech Elemental Combustion system 4010 CHNS-O (J. Bird) and HP 5890 Plus II GC (J. Bird).
The geochemistry laboratories are equipped with several acid fume hoods, an acid hood capable of hydrofluoric and perchloric acid work. These labs contain a Barnstead/Thermolyne nanopure infinity UV water systems, an Envrion Corp. Class 100 laminar flow hood, a range of balances (Cahn C-33 microbalance, Denver Instrument A-160 analytical balance and a Mettler bench-top), a centrifuge with temperature control, an oven (Lindberg Blue M), an incubator, a freeze-dryer (Labconco), several refrigerators, a shaker, an isotherm water batch, a sonicator and a UV digestor. A Coy anaerobic chamber with a platform shaker is also housed in Geochemistry lab for incubation studies.
