摘 要:采用高效液相色谱法,使用正相手性柱,以v(正己烷)∶v(异丙醇)=50∶50为流动相,在流速为1.0 mL/min,检测波长为210 nm的条件下,对20%精甲·氰霜唑悬浮剂中的精甲霜灵进行定量测定。使用反相ODS柱,以v(乙腈)∶v(水)=65∶35为流动相,在流速1.0 mL/min、检测波长280 nm的条件下,对20%精甲·氰霜唑悬浮剂中的氰霜唑进行定量测定。结果表明,精甲霜灵和氰霜唑的线性相关系数分别为0.9990和0.9990,标准偏差分别为0.09和0.03,变异系数分别为0.008%和0.004%,平均回收率分别为99.96%和100.06%。 |

Abstract:The content of Metalaxyl-M in Metalaxyl-M+Cyazofamid 20% SC was determined by HPLC using a normal phase chiral column, a mixture of n-hexane and isopropanol (50/50(v/v)) as mobile phase, a flowing rate of 1.0 mL/min, and a detection wavelength of 210 nm. The content of Cyazofamid in Metalaxyl-M+Cyazofamid 20% SC was determined by HPLC using a reverse phase ODS column, a mixture of acetonitrile and water (65/35(v/v)) as mobile phase, a flowing rate of 1.0 mL/min, and a detection wavelength of 280 nm. The experimental results indicated that the correlation coefficients of linearity for both Metalaxyl-M and Cyazofamid were 0.9990; the standard deviations were 0.09 and 0.03, respectively; the coefficient of variations were 0.008% and 0.004%, respectively; and the mean percent recoverys were 99.96% and 100.06%, respectively. |
