earth and environmental sciences
Electron and Optical Microscopy Lab
Tescan Vega 3 variable pressure (VP) scanning electron microscope equipped with a LaB6 source and a variety of analytical detectors including: secondary electron (SE), backscattered electron (BSE), cathodoluminescence, and VP-SE. SEM is also equipped with an Oxford Instruments X-MaxN 50 mm2 SDD x-ray detector and a NordlysMax2 electron backscatter diffraction (EBSD) detector for rapid characterization of mineral compositions and crystallographic orientations. Optical microscopes include Zeiss Axioskop40 transmitted/polarized light microscope, Leica Z6 APO macroscope, and a Leica MZ16 stereomicroscope for mineral picking. Support facilities also include grain and thin-section polishing equipment. For additional information on analytical capabilities and supporting instrumentation please visit the SEM Lab website.
Isotope Ratio Mass Spectrometry Lab
Thermo Delta V plus IRMS; the mass spectrometer is equipped with universal triple collectors and three additional Faraday cups for multiple sulfur isotope analyses by the SO-SO2 method in continuous flow. The Delta V is linked to the two elemental analyzer peripherals with a Conflo IV, two NC 2100 and ECS 4010 elemental analyzers to generate SO2 gas for multiple S isotope analysis and CO2 and N2 gases for C and N isotope analyses, respectively.
