摘 要:采用Diamond C18不锈钢柱[150 mm×4.6 mm(i.d.),5 μm]和二极管阵列检测器,以甲醇-水混合溶剂(80 ∶ 20,v/v)为流动相,流速1.0 mL/min、检测波长310 nm和柱温35℃,建立了茚虫威制剂10%悬浮剂的高效液相色谱分析方法。茚虫威在0.5~10 mg/L的浓度范围内,其峰面积(y)与质量浓度(x)呈现良好的相关性,其线性回归方程为y=23 372x+3 238.2,R2=0.999 3。在10%悬浮剂中,茚虫威5个添加浓度水平的平均回收率为99.29%,相对标准偏差(RSD)为1.05%,说明所建立的方法快速、灵敏度高、重现性好,可用于茚虫威10%悬浮剂产品质量控制与分析。 |

Abstract:A quantitative high performance liquid chromatography method using diode array detector has been developed for the determination of the active ingredient indoxacarb in the formulation 10% suspension concentrate (SC). A diamond C18 stainless steel column [150 mm×4.6 mm(i.d.),5 μm] was used with mixture of methanol-water(80 ∶ 20,v/v)as the mobile phase at a flow rate of 1.0 mL/min,the column temperature 35℃ and the ultraviolet detection wavelength 284 nm. There existed good linear correlation between peak area(y) and concentration(x) of indoxacarb in the concentration range of 0.5~10 mg/L with the regression equation y=23 372x +3 238.2,R2=0.999 3. The average recovery of the five spiked levels for indoxacarb 10% SC was 99.29%,relative standard deviation 1.05% and coefficient of variation 0.01%,suggesting that the method should be fast,sensitive,reproducible and practical for the quality control and analysis of indoxacarb 10%SC during the manufacture of the product. |
