Neptune Isotope Laboratory

Request Info
The Neptune Isotope Laboratory at the UM Rosenstiel School provides a clean-room enclosure with several class-100 vertical and horizontal laminar flow hoods, two high-purity water systems, sub-boiling acid distillation units and two, class-100 trace metal workstations for low-blank sample processing and wet chemistry. The lab is also equipped with a ThermoFisher Neptune Plus, high performance Multi-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) and a New Wave Excimer 193 nm Laser Ablation (LA) system.

The facility is capable of making the following routine measurements, and continues adding new isotope systematics:
  • High-precision analysis of Li, B, Ca, Mg and, Fe isotopes.
  • High precision analysis of Hf and the Rare Earth Element (REE) isotopes
  • High-precision analysis of Sr isotopes using wet chemistry and LA-MC-ICP-MS.
  • Bulk elemental analysis of the REE, Sc and Y using MC-ICP-MS
  • Closed-system U-Th geochronology of carbonate rocks, including corals and speleothems
