摘要
对气相色谱仪测定西葫芦中三唑磷农药残留的结果进行了测量不确定度评定,并分析了主要不确定度来源,提出了测量不确定度的控制措施及应用方法。由于含有扩展不确定度的测量结果落在了农药残留限量值的两侧,故对西葫芦的质量作出了“不能判定”的结论,同时,指出了农产品质量判定的一般规则和抽检工作的注意事项。
The measurement uncertainty of determination of triazophos pesticide residues in Zucchini by gas chromatography is evaluated,with the main sources of uncertainty analyzed,and the control measures and application methods of uncertainty put forward.The measurement results containing extended uncertainty fall on both sides of the pesticide residue limit value,so the conclusion of“not determined”for the quality of Zucchini is made,and the general rules for judging the quality of agricultural products and the matters that need attention in sampling detection are pointed out.
