Determination of Rare Earth Elements in Sixteen Silicate Reference Samples by Icp‐ms After Tm Addition and Ion Exchange Separation

This study reports the results of thirteen rare earth elements (REE) in sixteen geochemical reference samples. The analytical procedure involved dissolution of a whole rock or mineral separate, spiking with Tm, and separation of the REE using a simple ion‐exchange chromatography procedure. The resulting REE solutions were analysed by ICP‐MS. The results are compared with literature values. The agreement between our data and recommended or ID‐TIMS values is very favorable. The precision of the technique is better than 5% (2) for all the REE.
