摘要
采用Envi-carb/NH2复合柱净化,GC/MS法检测,对提取条件、净化条件和检测条件充分优化后,建立了卷烟主流烟气总粒相物中4种氨基甲酸酯类农药(久效威、甲奈威、克百威和抗蚜威)含量的快速分析方法.该方法的线性范围为0.01~10.0mg/L,相关系数(R)大于0.996 6,日内、日间相对标准偏差(RSD)均小于6.97%,检测限(LOD)均为10μg/L,样品的加标回收率均大于90.20%~92.80%.方法用于卷烟主流烟气总粒相物中氨基甲酸酯类农药含量的测定,结果令人满意.
A rapid analysis method based on solid-phase extraction(SPE) and gas chromatography-mass spectrometry(GC/MS) was established to analyze four carbamate pesticides in mainstream cigarette smoke.The quality control problem of this analytical method was discussed particularly.The linear range of this method was 0.01~10.0 mg/L.The linear correlation coefficient(R) was higher than 0.996 6.The intra-day and inter-day relative standard deviations(RSD) were less than 6.97%.And the recovery values ranging from 90.20% to 92.80%.The method was successfully used on the determination of carbamate pesticides in mainstream cigarette smoke.
