Improving the utility of LA-ICP-MS for isotope ratio analyses of single particles with application to uranium oxide [PDF]

open access: yes, 2016
The determination of the isotopic composition of single uranium oxide particles, size 0.3-2 μm, for nuclear safeguards is current performed by either thermal ionisation mass spectrometry (TIMS) or Secondary Ion Mass Spectrometry (SIMS).

In situ U-Pb Isotope Dating Techniques for Sandstone-type Uranium Deposits

open access: yesYankuang ceshi, 2020
BACKGROUND Uranium mineral dating has been difficult to ascertain in mineralization chronology. With the development of in situ U-Pb isotope dating technology, it is possible to directly date ore minerals (uranium minerals).

Improving Precision and Signal/Noise Ratios for MC-ICP-MS

open access: yesProcedia Earth and Planetary Science, 2015
AbstractHigh precision measurements of isotope ratios are improved by continuous innovations in multi-collector isotope ratio mass spectrometers. Recently, the Thermo Scientific TRITON Plus TIMS and NEPTUNE Plus MC-ICP-MS benefitted from the implementation of Faraday cup current amplifiers with 1013 ohm feedback resistors.
