Within the Earth & Planetary Sciences building (Olin Hall) on the Homewood Campus, we are fully equipped to not only prepare rocks for petrography, trace element geochemistry and geochronology, but do the analyses! Our labs and equipment include...
LA–ICP–MS Lab
-- Agilent 8900 triple quadrupole inductively-coupled-plasma mass spectrometer
-- Agilent autosampler for solution work
-- Teledyne Cetac Analyte G2 193 nm laser ablation system for in situ work
-- analytical focus on trace element mapping and in situ geochronology
-- full access opportunities for all student projects in the TeMPO Lab
Scanning Electron Microscopy and X-ray Micro-Computed Tomography Labs
-- Owned and operated by Johns Hopkins Materials Characterization & Processing (link), but located in Olin Hall
-- Thermo Helios G4 UC FIB–SEM with backscatter, secondary electron and cathodoluminescence detectors
-- electron backscatter diffraction (EBSD) and energy dispersive spectroscopy (EDS)
-- RX Solutions X-ray µCT scanner, with up to sub-µm resolution (depending on sample size)
Microscope Lab
-- Leica DM2700 P petrographic microscope with reflected light unit
-- Leica M125 stereoscope with both transmitted and reflected light, and polarizers
-- Leica S8APO stereoscope with gooseneck lights
-- Leica DFC550 camera and mounts for use on all scopes
-- Canon Canoscan 9000F film scanner (with polarizing sheets) for scanning petrographic thin sections
-- all necessary equipment for making analytical mounts for LA–ICP–MS
Rock Processing and Mineral Separation Facilities
-- rock saws
-- grinding and polishing equipment
-- Fritsch jaw crusher and ring-and-puck mill (hardened steel and tungsten carbide)
-- sieves and two Ro-Tap sieve shakers
-- Gemeni gold table
-- Frantz isomagnetic separator
-- heavy liquids (including non-toxic options) for density separation of accessory minerals
-- Leica EZ4W picking stereoscope
