초록
Fly ash samples collected from municipal waste incinerator were prepared for proficiency testing of dioxin analysis. They were used to evaluate the homogeneity and stability through the several steps. Specially, one way ANOVA was used as analysis method in this study. In case of identified samples, measurement model equation of target isomer in analysis were formulated. Then uncertainties of results were calculated by selection of uncertainty cause and by calculation of uncertainty quantification, synthesis uncertainty, and expansion uncertainty. The portions of the uncertainties resulted from the amount of internal standard, the separation rate of sample, the relative reaction factor (RRF) of GC/MS, and efficiency of sample extraction were 35.6%,35.0%, 25.6%, 3.7%, respectively.
