西维因、叶蝉散、呋喃丹三种农药标准物质的研制

Certified Reference Materials of Pesticide Carbaryl, Isoprocarb and Carbofuran

介绍了西维因、叶蝉散、呋喃丹三种农药标准物质的定值测定及均匀性、稳定性检验。实验方法为高效液相色谱法（ Ｈ Ｐ Ｌ Ｃ）和差示扫描量热法（ Ｄ Ｓ Ｃ）。三种农药标准物质纯度定值的不确定度为±０２％ 。

The determination of the specific values,homogeneity and stability of the certified reference materials of Pesticide Carbaryl,Isoprocarb and Carbofuran by means of High Performance Liquid Chromatography(HPLC) and Differential Scanning Calorimeter (DSC) are described in this paper.The measurement uncertainty of the purity of the three CRMs is ±0 2%.
