摘  要:
依据NY/T761.3-2004方法对残杀威残留量的测量不确定度进行分析和评定。分析结果表明:残杀威残留量测定的合成相对标准不确定度为3.62%。该测量过程所产生的测量不确定度主要来源于标样溶液配制、样品称量、样品稀释、样品溶液配制、标样溶液峰面积和样品溶液峰面积的测量,其相对标准不确定度分别为0.74%、0.023%、0.73%、0.30%、2.05%、2.78%。

摘  要:
By the method of NY/T 761.3-2004,propoxur pesticide residue in vegetables and fruits was determined, and uncertainty of measurement for the determination of propoxur residue was evaluated.The total relative standard uncertainty of measurement appeared in the determination is 3.62%.It was mainly caused by that in the standard material solution preparation,the sample weigh,the sample dilute,the sample solution preparation,the determination of the standard solution area and the sample solution area.Their relative standard uncertainty is 0.74%,0.023%,0.73%,0.30%, 2.05%,2.78%respectively.
