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 all the work/analyses! Our labs 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, Ingram thin section saw and grinder
-- grinding and polishing equipment
-- Fritsch jaw crusher and ring-and-puck mill (hardened steel and tungsten carbide)
-- sieves and two Ro-Tap sieve shakers
-- hydraulic pellet press
-- Gemeni gold table
-- Frantz isomagnetic separator
-- heavy liquids for density separation of accessory minerals
-- Leica EZ4W picking stereoscope
