Abstract:

According to the testing process for determination of gold in gold ore by AAS，we systematically analyzed the source of the uncertainty.The uncertainty of the determination results are made up of the uncertainty components which include standard compounded，sample preparation，curve fitting，sample uniformity，examination duplication and so on.Measurement results are obtained，with the standard uncertainty of 0.03 ug/g and the expanded uncertainty of 0.06 ug/g.Through the evaluation concluded the main factors influencing the measurement accuracy，and we should operate in strict accordance with the procedures in the later work.

Key words: AAS, Gold ore, Measurement uncertainty
