Abstract：To establish a method for the evaluation of the uncertainty in the NaF content determination of evacuated receptacle by FAAS.According to the measurement process,each component of uncertainty was calculated by analyzing the various variable sources of uncertainty generally,and a mathematical medel was established.The combined standard uncertainty and the expanded uncertainty were then finally obtained.The expression of the results of the NaF content determination of evacuated receptacle was 2.15 ±0.052 mg/L (k =2),the combined standard uncertaintywas 0.026 mg/L,the expanded uncertainty was 0.052 mg/L.This method is suitable for evaluating of the NaF content determination of evacuated receptacle by FAAS,and it is important meaning to give the dispersion of the determined results.
