摘　　要：为了探讨同一色谱条件下两种有效成分同柱分析的可行性,通过液相色谱对22.4%螺虫乙酯·氯噻啉悬浮剂样品进行分析。以乙腈和水为流动相,以ZORBAXXDB-C18柱为分离柱,使用紫外检测器,在254nm波长下对22.4%螺虫乙酯·氯噻啉悬浮剂进行高效液相色谱分离和定量分析。结果表明:螺虫乙酯和氯噻啉的线性相关系数分别为0.9995和0.9994;标准偏差分别为0.059和0.047,变异系数分别为0.35%和0.83%,平均回收率分别为99.72%和99.59%。该方法操作简单,精密度和准确度高,线性关系好,而且一根柱子能同时测定试样中两种有效成分。In oder to investigate the analysis feasibility of two active ingredients with one column under the same HPLC condition, the analysis method for 22.4% spirotetramat and imidaclothiz SC by HPLC. Using ZORBAX XDB-C18 column and UV detector at 254 nm wavelength, with acetonitrile-water as the mobile phase, 22.4% spirotetramat and imidaclothiz SC in the samples were separated and quantitatively analyzed. The results showed that the linear correlation coefficients were 0.999 5 and 0.999 4, the standard deviation were 0.059 and 0.047,the coefficients of variation were 0.35% and 0.83%, the average recoveries were 99.72% and 99.59%. The method was simple, with high accuracy, precision and good linear relationship. The two active ingredients can be detected with a same column.
