Clean Analytical Geochemistry Laboratory

Completed in 2016, the department houses a new ~750 sq ft clean lab complex. The lab includes Class 1000 room conditions, as well as eleven Class 100 laminar fume hoods and/or work cubbies, two weighing stations, acid distillation fume hood, clean MilliQ water supply, a fume hood for beaker cleaning, and ample storage space for samples and materials.聽 The lab will be used primarily for sample dissolution and column chromatography for TIMS analysis.

Thermal Ionization Mass Spectrometry (TIMS) Facility

Installed in 2016, Isotopx Phoenix TIMS instrument; equipped with nine movable Faraday detectors and an ion counting Daly detector. The TIMS permits acquisition of high precision聽143Nd/144Nd and聽87Sr/86Sr isotope data for the smallest samples down to the sub-nanogram level.聽 A New Wave MicroMill device for high precision sampling will be available in the adjacent mineral preparation laboratory.

Isotope Ratio Mass Spectrometry Lab

Upgraded in 2016, 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.

Electron and Optical Microscopy Lab

Upgraded in 2015, Tescan Vega 3 variable pressure (VP) scanning electron microscope equipped with a LaB6聽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聽50 mm2聽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聽SEM Lab website.
