| The authors analyse for Zr and Ce in a uranium containing matrix. This application is relevant for the analysis of nuclear fuel rods, without the need for dissolving in HF. Different LODs were determined depending on whether analysis of binary (U+Ce or U+Zr) or ternary (U+Ce+Zr) oxides were undertaken. The presence of Zr was found to suppress the Ce and U emission intensities. A reduction in laser to sample coupling, leading to lower plasma temperatures was postulated as the cause of the changes. In all, the authors identified 33 Ce lines and 25 Zr lines which were viable for calibration. | |||||
