| Abstract: | According to the method of GB/T 5009. 17 -2003, various sources of uncertainty from the determination procedure of total mercury in Oyster powder by Atomic Fluorescence Spectrometer （AFS） were assessed. The calculation formula was deduced and then each component＇s uncertainty was calculated through analyzing the various variables among the procedures. The combined uncertainty was then finally obtained by synthesizing the uncertainties of various component variables. The influence of the identified uncertainty of the analytical result was evaluated, and references for the reliability and consistency of the testing data in the laboratory were made. |
