气相色谱法测定3种化学驱蚊成分

Component determination of 3 chemical mosquito repellents by GC

[目的]建立了一种快速有效测定驱蚊产品中避蚊胺、驱蚊酯、羟哌酯3种驱蚊成分的气相色谱测定方法。[方法]采用SE-54毛细管柱为色谱柱和FID检测器,以己二酸二丁酯为内标物,丙酮为溶剂,内标法定量。[结果]3种驱避剂在质量浓度4~12 g/L范围内线性关系良好,相关系数不小于0.99961,回收率为98.9%~103.2%,RSD值为3.8%~7.2%。[结论]该法快速、操作简便且准确,可满足定量分析需求。

[Aims]This study aims to establish a GC method for quickly and effectively detection of diethyltoluamide,ethyl butylacetylaminopropionate and icaridin in mosquito repellent products.[Methods]The sample was analyzed by SE-54 column,FID detector and internal standard method,with dibutyl adipate as internal standard and acetone as the solvent.[Results]The method presented good linear relationship when the concentrations of the three repellents ranged from 4 to 12 g/L,and the correlation coefficients were not less than 0.99961.The recovery was 98.9%-103.2%,and the RSD was 3.8%-7.2%.[Conclusions]This method is fast,simple and accurate,meeting the requirements of quantitative analysis.
