固相萃取-气相色谱/质谱联用法测定卷烟主流烟气中的香兰素和乙基香兰素
Chinese Journal of Analysis Laboratory(2020)
Abstract
采用固相萃取-气相色谱/质谱联用技术,建立了一种同时测定卷烟主流烟气中香兰素和乙基香兰素的方法.方法 优化了萃取条件,考察了萃取溶剂、萃取时间对检测结果的影响.通过硅藻土固相萃取柱净化并浓缩后,选取DB-HeavyWAX毛细管柱进行目标物分离,以香兰素-d3作为内标,对香兰素和乙基香兰素进行定量分析.结果 表明,香兰素和乙基香兰素在浓度0.2~ 20.0 mg/L范围内具有良好的线性关系,其检出限分别为9.1 ng/支和6.5 ng/支,回收率均在96.3%~107.7%之间.
