气相色谱法检测驱蚊环、驱蚊贴中的化学驱蚊成分

Detection for Chemical Mosquito Repellent in Anti-mosquito Wristbands and Stickers by Gas Chromatography

旨在建立一种分析方法,以测定近年来市场上出现的驱蚊环、驱蚊贴等新型驱蚊产品中可能存在的避蚊胺、驱蚊酯、羟哌酯等化学驱蚊成分。确定了超声萃取的前处理方法、气相色谱法(火焰离子化检测器)的色谱条件,以邻苯二甲酸二戊酯为内标物的内标定量方法。该方法前处理过程简便、线性和重复性良好,检出限<0.01%,能够满足检测要求。通过对94个实际样品的测定,证明该方法具有较好的实用性。

The method was established to detect the possible chemical mosquito repellent（DEET,BAAPE,Bayrepel,etc） in antimosquito wristbands and stickers which were available in the market recently.The detection was done with pretreatment method of ultrasonic extraction,detection method of gas chromatography with FID detector and internal standard quantitative method with diamyl phthalate as internal standard. The method meets the test requirements,based on the advantages of simple pretreatment process,good linearity and repeatability,detection limit less than 0. 01%.The detection results of 94 samples show that this method has good practicability.
