| Abstract: | In this paper, the detcrminaiion of 8 trace RE elements - Ce, Nd, Sm, Eu, Gd, Dy, Er and Yb, in pure materials or plant samples by IDMS is described. Corrections of interference and fractionation are discussed. For this method, the reproducibility is better than 1% , sensitivity is better than 2.3X10-9g, accuracy better than 5%. |
