介绍了24%丙炔·吡嘧磺隆油悬浮剂的液相色谱分析方法。选用甲醇+水(用磷酸调至pH=5.0)=80+20(V/V)为流动相,在230nm对两种有效组分进行液相色谱分离和外标法检测。该方法的精密度和准确度均较好,可以用作产品的分析检测和质量控制。
The liquid chromatographic analysis method of 24% propyne and pyrazosulfuron ethyl ester oil suspending agent was introduced. The methanol and water (adjusted to pH = 5.0 with phosphoric acid) = 80 + 20 (V / V) were used as the mobile phase. The two active components were separated by liquid chromatography and detected by external standard method at 230 nm. The precision and accuracy of the method are good, can be used for product analysis and testing and quality control.
