本文结合NY/T 761-2004农药残留分析方法,把毒死蜱、氯氰菊酯、茚虫威、烯酰吗啉等4种农药残留量测定不确定度分为称量、提取、净化、色谱测定等分量,用校正因子来表征测定过程中的重复性不确定度,并加以评定,为试验室质量管理和控制提供科学依据。结果表明,色谱定量重复性误差及同一样品的重复性误差所引入的不确定度是影响残留量测定不确定度的较大因素。

According to NY/T 761-2008, the uncertainty in determination of 4 kikds pesticdes （including indoxacarb, dimethomorph, chlorpyrifos and eypermethrin） residues is divided into 5 different parts in this paper, including weighting, extract, cleansing, determining by GC, and the correct factor as a token of repeating test and sample. The aim of reasonable evaluation of uncertainty of measurement is to provide scientific basis for the laboratory quality management and control. In the process of the test, the eorrect factor and repeat determination value are the main factor in the measurement uncertainty assessing.
