30%甲酰胺基嘧磺隆水分散粒剂高效液相色谱分析方法

Study on Analytical Method of Foramsulfuron 30% WG by HPLC

采用高效液相色谱仪分析30%甲酰胺基嘧磺隆水分散粒剂的质量分数,使用C_(18)不锈钢反相色谱柱和紫外可变波长检测器,以甲醇+磷酸溶液为流动相,用外标法对有效成分进行定性、定量分析。甲酰胺基嘧磺隆线性相关系数为0.999 9;标准偏差为0.36;变异系数为1.09%、0.81%;平均回收率为102.11%。结果表明,此检测方法灵敏、快速,适用于30%甲酰胺基嘧磺隆水分散粒剂的含量检测。

A method for separation and quantitative analysis of foramsulfuron 30%WG by HPLC with methanol and H3PO4 solution as mobile phase,Agilent TC-C_(18) column and UV Vis wavelength deterctor was described.The result showed that the linear correlation coefficient was 0.9999,the standard deviation was 0.36,the variation coefficient was 1.09%,and the average recovery was 102.11%.The results showed that the developed method was sensitive,rapid and suitable for the content determination of 30%formylsulfuron water dispersible granules.
