Determination of trace amounts of REE with ICP spectroanalyzer JY 38 controlled by PDP 11/03 computer was described. The geochemical samples were fused with Na202 and separated by ion-exchanging on a column (0.6 × llcm) of cation exchange resin. The detection limits of this method are from 0.23ng/1(Lu) to 8. leg/1(Ce) for 15 RE elements. The relative standard deviation for ten determinations of GSD reference samples is about 3%.
