Current and developing applications in the GOUGE Lab include:
U–Pb geochronology of zircon, apatite, titanite, and carbonates
Trace- and rare-earth-element (REE) analysis
Spatially resolved laser-ablation elemental and isotopic mapping
Development of new analytical approaches for tectonic, impact, and planetary materials
Teledyne Iridia 193 nm Laser Ablation System
Teledyne Iridia 193 nm Laser Ablation System
The Iridia was installed in August 2026. The cobalt cell has flexible analytical performance times from less than a millisecond to over a second, advanced optics, and a dynamic z-prime cell to ensure aerosol removal. The Iridia washout times has a tunable, dynamic range, and up to 300 Hz frequency.
Agilient 8900 Triple Quadropole ICP-MS
Agilient 8900 Triple Quadropole ICP-MS
Unlike conventional single-quadrupole ICP-MS instruments, the Agilent 8900 (installed July 2026) uses tandem mass spectrometry (MS/MS), with two mass-filtering quadrupoles separated by a collision/reaction cell. This configuration provides precise control of ion–molecule reactions and enables effective removal of spectral interferences, expanding the range of elements and isotope systems that can be measured accurately.
