• MC-ICP-MS: Unlocking the Isotope Toolbox
    • Karen Spaleta (Alaska Stable Isotope Facility)
    • March 18, 2019

Multi-Collector Inductively-Coupled-Plasma Mass-Spectrometry (MC-ICP-MS) is a technique that measures radiogenic and non-traditional stable isotopic systems, and can complement traditional stable light isotope analyses.

Isotopic systems are a valuable tool to study topics across many disciplines including geochemistry, ecology, geochronology, oceanography, paleoecology, marine science, fisheries, mineral exploration, hydrology, archaeology, and more!

The Alaska Stable Isotope Facility (ASIF) acquired an NSF-MRI funded MC-ICP-MS with installation of the instrument and a Laser Ablation (LA) sample introduction system occurring last year. I will provide an overview of the instrument’s capabilities, and talk about a few of our initial projects involving Sr isotopes. I will also discuss potential Arctic research applications of other isotopic systems including Hg, Li, U, Pb, Cu, and Ba. This MC-ICP-MS is the only instrument of its kind in Alaska, and we’re very excited to share about its capabilities and potential applications to Arctic research.
