30%噁霉灵·噻呋酰胺悬浮剂高效液相色谱分析

Analysis of Hymexazol+Thifluzamide 30% SC by HPLC

采用高效液相色谱法,以甲醇+乙腈+水为流动相,使用安捷伦C_(18)不锈钢柱和紫外吸收检测器,在220 nm波长下对30%噁霉灵·噻呋酰胺悬浮剂中有效成分进行定量分析。结果表明,噁霉灵和噻呋酰胺的线性相关系数分别为0.999 8和0.999 1,标准偏差分别为0.030和0.032,变异系数分别为0.30%和0.16%,平均回收率均为99.4%。

A method for separation and quantitative analysis of hymexazol ＋ thifluzamide 30% SC was described by HPLC, using methanol, acetonitrile and water as mobile phase, on Agilent ODS-C18 chromatographic column, at 220 nm wavelength. The results showed that the linear correlation coefficients of hymexazol and thifluzamide were 0.999 8 and 0.999 1, the standard deviations were 0.030 and 0.032, the coefficients of variation were 0.30% and 0.16%, the average recoveries were both 99.4%.
