依据JJF 1059.1-2012方法,对气相色谱法测定蔬菜中苯硫磷农药残留量的不确定度进行分析评定。测定过程中产生的不确定度主要来源于标准物质称量和样品测量重复性。分析结果表明:蔬菜中苯硫磷残留量为0.012 m g/kg时,其扩展不确定度为0.0034 m g/kg(k=2)。
依據JJF 1059.1-2012方法,對氣相色譜法測定蔬菜中苯硫燐農藥殘留量的不確定度進行分析評定。測定過程中產生的不確定度主要來源于標準物質稱量和樣品測量重複性。分析結果錶明:蔬菜中苯硫燐殘留量為0.012 m g/kg時,其擴展不確定度為0.0034 m g/kg(k=2)。

By the method of JJF 1059.1-2012, the uncertainty in measurem ent for EPN in vegetables by gas chrom atography was evaluated. The main sources of uncertainty resulted from determ ination process w ere the standard material weighing and the measuring repeatability. The evaluation result showed that the expanded uncertainty of measurem ent was 0.0034mg/kg (k=2), as 0.012mg/kg EPN residue in vegetables.
