The uncertainty in measuring aldicarb and its metabolites (aldicarb-sulfone and aldicarb-sulfoxide ) in ginger by LC-MS/MS was analyzed. A mathematical model was established , all the influence factors on measuring uncertainty were found out,and each uncertainty was evaluated and calculated.The relative combined standard uncertainty and expanded uncertainty in measuring aldicarb and its metabolites (aldicarb-sulfone and aldicarb-sulfoxide) in ginger by LC-MS/MS were worked out. The major sources of uncertainty included the recovery rate, retest and volume.
