The Materials Characterization Facility (MCF) at Georgia Tech has installed a new inorganic m spectrometry facility. The facility includes two new inductively couple plasma mass spectrometry (ICP-MS) systems: a Thermo iCAP RQ quadrupole ICP-MS for streamlined and high-throughput determinations of elemental concentrations and a Thermo Neoma multicollector ICP-MS with collision cell technology for the precise determinations of isotope ratios within a given sample.
Each instrument can measure elemental variability in both dissolved aqueous samples as well as solids/minerals via laser ablation microsampling from a Teledyne Iridia laser ablation system. Together the system can measure isotopes at precision in elemental systems from Li and U.
Planned applications include: (1) high-resolution measurements of Ca, Sr, Ba, Mg, and B elemental and isotopic variability in seawater and marine and terrestrial carbonates for paleoclimate reconstructions, (2) (U-Th)/Pb dating and Hf isotope measurements to study the origin of critical mineral deposits, with a potential engineering application and the development of novel methods for increasing precision/accuracy and minimizing sample consumption during routine analyses of water quality and environmental contamination.
The MCF welcomes users interested in these and other potential applications of this new facility to their scientific and engineering research to contact David Tavakoli (atavakoli6@gatech.edu).
