摘要
介绍了应用液相色谱法同时测定除草剂双甲胺草磷(H9201)与吡嘧磺隆复配制剂两种有效成分含量的测定方法;采用乙腈-0.1%酸性水为流动相、C18柱、紫外检测器。双甲胺草磷与吡嘧磺隆的RSD分别为0.28%和0.32%,方法的线性相关系数均为0.9999和0.9998,平均回收率分别为99.58%和99.65%。
The analysis of H9201 and pyrazosulfuron in mixture formulation by HPLC with C18 column using acetonitrile ＋ water ＋ acid as mobile phase and UV detector was introduced in this paper. Linear regression coefficient for H9201 and pyrazosulfuron was 0.999 9 and 0.999 8, respectively. The average recovery for H9201 and pyrazosulfuron was 99.58% and 99.6%, and RSD 0.28% and 0.28%, respectively.
