摘要
建立蚊香中环戊烯丙菊酯、四氟甲醚菊酯、氯氟醚菊酯、炔咪菊酯4种有效成分分析方法。采用HP-5毛细管柱分离,气相色谱仪-火焰离子化检测器检测,保留时间定性,内标法定量,结果组分间分离效果好,所有组分在0.02～5.00g/L质量浓度范围内具有良好线性关系,相关系数大于0.9999,回收率在98.1%～101.8%之间,相对标准偏差RSD小于2%,方法检出限在0.001%～0.002%之间。
A gas chromatography method with hydrogen flame ionization detector for the simultaneous detection and confirmation of four effective components terallethrin,dimefluthrin,meperfluthrin and imiprothrin in mosquito-repellent incense. After separated by HP-5 capillary column,the analytes were qualified by the retention time and quantified by internal standard method. Under the optimized conditions,the limits of detection were in the range of 0.001-0.002% with precisions （RSDs） lower than 2%,and all of the analysis compounds exhibited good linearity over a range of 0.02-5.00 g/L. The linear correlation coefficient was more than 0.9999. The mean recoveries varied between 98.1 and 101.8%.
