Quantitative and isotopic analysis of single micrometer-sized uranium particles using multiple mass spectrometric techniques

Uranium isotopic analysis in unpurified solutions by ICP-MS

“…Improvements in mass spectrometry technology have led to enhanced precision and lower detection limits that have strengthened understanding of a variety of natural and man-made processes from the micro to the macro scale. [32][33][34][35][36][37] For bulk sample analysis, two types of mass spectrometers are typically used. Thermal ionization mass spectrometry (TIMS) has been considered the conventional method with decades of supporting method development and high precision analytical data using either partial or total evaporation methods.…”

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Multiple mass spectrometric techniques were tested by Park et al for micrometer-sized U particles, combining measurement with a micro-manipulating technique. 196 The most accurate and precise measurements were achieved using SIMS when compared with SEM-TIMS and SEM-MC-ICP-MS. Following U particle dissolution and isotope dilution measurement using MC-ICP-MS, the U mass per particle was close to the reference value.…”
