ICP-MS is the most commonly used atomic spectrometry technique for the measurement of trace REEs.The measurement of mid-and high-mass REEs in a low-mass REE matrix is,however,very challenging for ICP-MS because REEs have high metal-oxide(M-O)bond strengths,and the oxide ions of the low mass REEs overlap the preferred isotopes of the mid-mass and high-mass REEs.
