Laboratory
|
Laboratory experiences will include full access and use of ThermoElectron isotope ratio mass spectrometers and Picarro cavity-ring down spectrometers. The IRMS is equipped with elemental analyzers, continuous flow capacities, GC, TCEA, pre-con, laser, common-acid-bath. Available also are vacuum preparation lines for organic and inorganic compounds of biological and environmental interest. |
