Description

This study shows that the effectiveness of ultra-trace-level uranium isotopic analysis by thermal ionization mass spectrometry can be increased by treatment of uranium samples with graphite powder, which results in a 1.9-fold enhancement of uranium ion signal intensity and thus improves analytical accuracy, precision, and measurement uncertainty. Additionally, a mechanistic rationalization of the observed intensity enhancement is provided. (author)
