| Abstract: | The uncertainty in determination of fenitrothion and parathion in rice by gas chromatography was evaluated.The main sources of uncertainty resulted from the determination process were discussed and calculated.The combined standard uncertainty and expand standard uncertainty of fenitrothion determination were 0.0030 mg/kg and 0.0060 mg/kg(k=2) respectively.And the combined standard uncertainty and expand standard uncertainty of parathion determination were 0.0022 mg/kg and 0.0044 mg/kg(k=2) respectively.The ... |
