Direct determination of metallic impurities in nuclear-grade boron carbide by slurry sampling total reflection X-ray fluorescence spectrometry and ICP atomic emission spectrometry subsequent to ultra-high-pressure sample digestion

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

“…Methods for the preparation of boron nitride 158 and of boron carbide 159 prior to analysis have been reported. These papers are welcome, because ceramics are notoriously difficult to bring into solution.…”

“…Yuan et al developed a slurry technique for the determination of a suite of 10 elements using TXRF. 159 The dispersant polyacrylateamine was used at different concentrations to ensure that aggregation did not occur. A slurry concentration of 10 mg mL −1 was suitable.…”
