Description
Summary:Quality evaluation of the k.sub.0-standardized neutron activation analysis (k.sub.0-NAA) at Dalat research reactor (DRR) has been implemented by analyzing the SMELS, a synthetic multi-element standard material as well as the certified reference materials for purposes of validation and verification of the method. The results revealed that the k.sub.0-NAA established at DRR has met the requirements of multi-element analysis for the intended applications with about 42 elements: Al, As, Au, Ba, Br, Ca, Ce, Cl, Co, Cr, Cs, Cu, Dy, Eu, Fe, Hf, I, In, K, La, Mg, Mn, Mo, Na, Nd, Pr, Rb, Sb, Sc, Se, Sm, Sr, Ta, Tb, Th, Ti, U, V, W, Yb, Zn and Zr in matrices of environment, geology and biology among others. Evaluation criteria for the laboratory quality used in this work are the statistical analysis parameters namely: u-scores, laboratory result/certified value ratios and relative biases as well as the control charts those are shown in the paper.
