Ken Williams Radiogenic Isotope Geosciences Laboratory

The R. Ken Williams ’45 Radiogenic Isotope Geosciences Laboratory at Texas A&M is a 1550 ft two laboratory complex that consists of a perchloric acid fume hood room, gown-up room, dilution and weighing room, clean general chemistry room (<2000 particles >0.3 μm per ft 3 air), and ultra-clean chemistry room (<100 particles >0.3 μm per ft 3 air). Clean-air workstations in each chemistry lab are better than 100 particles >0.3 μm per ft 3 air and two recirculating laminar flow hoods both tested at zero particles. Four ThermoScientific mass spectrometers: a Triton thermal-ionization mass spectrometer, an Element XR high-resolution inductively-coupled plasma mass spectrometer, an iCAP quadrupole inductively-coupled mass spectrometer, and a Neptune Plus multicollector inductively coupled plasma mass spectrometer. In addition, coupled to the mass spectrometers we have a Photon Machines Analyte 193 laser ablation system. Available equipment accessories for the inductively-coupled mass spectrometers include an APEX heated desolvation system (ESI, Omaha), a Spiro macroporous desolvation unit (ESI, Omaha), several autosamplers, and associated mass spectrometry hardware for low-level elemental and isotopic analysis.
