For direct quantitative determination of rare earth elements(REE) in REE-rich minerals, a most acceptable reference material NIST 610 might be an alternative external calibration standard due to the lack of matrix-matched reference materials. Here, we aimed to develop an analytical method for direct quantitative determination of REE concentrations in REE-rich minerals via laser ablation-inductively coupled plasma-mass spectrometry(LA-ICP-MS). The results show that the REE concentrations measured via LA-ICP-MS using NIST 610 as an external standard are in good agreement with reference values with relative percentage difference(D r) mainly less than 15%. Overall, these results demonstrate that our proposed analytical method is robust and accurate for direct quantitative determination of REE concentrations in REE-rich minerals.
