| Abstract: | Human hair certified reference material(GBW09101) homogeneity was evaluated by determining 10(-6) quantity Cu, Zn, Mg, K, Pb, Fe, Ca, Na and S on sample weight from 100 mg to 300 mg by neutron activation analysis, atomic absorption spectrometry and X-ray fluorescence analysis. Using variance F test, the results(F < F alpha) is not differ significantly and this material could be considered homogeneous. In this paper, an evaluation of homogeneity was made by Inductively Coupled Plasma Mass Spectrometry through the determination of 10(9) quantity La, Sm, Y in 0.2000 g samples. Using t test and F test, the results (magnitude of t < t alpha, F < F alpha) were satisfactory. |
