气相色谱法测定蔬菜中联苯菊酯残留量的不确定度

Uncertainty Analysis of Bifenthrin Residues in Vegetables by GC

依据NY/T 761—2008 《蔬菜和水果中有机磷、有机氯、拟除虫菊酯和氨基甲酸酯类农药多残留的测定》第2部分(方法一)对蔬菜中联苯菊酯残留量测定不确定度进行分析和评定。建立测量模型,并从6个方面进行评定,此次试验合成的扩展不确定度为0.022 mg/kg (k=2)。

According to NY/T 761—2008《Pesticide multiresidue screen methods for determination of organophosphorus pesticides, organochlorine pesticides,pyrethroid pesticides and carbamate pesticedes in vegetables and fruits 》analyzed the uncertainty of bifenthrin residues in vegetables. A measurement model was established and from six aspects to assess. The uncertainty of synthesis expansion was 0.022 mg/kg（k=2）.
