Abstract
To evaluate the uncertainty of Pb content in Ginseng detected by ICP MS.Mathematical model of Pb content in Ginseng was established.The uncertainties of factors in mathematical model were analyzed and calculated.The results showed that Urelsam (C) was the main source of U (X).According to JJF1059-2012,the component uncertainties were synthesized and extended.The expanded uncertainty of 0.041mg/kg (k=2) were obtained at the confidence probability of 95％ and coverage factor of 2.The method provides references for the uncertainty evaluation of Pd in Ginseng by ICP MS.关键词
