气相色谱法测定烟草浸膏中的烟碱

Determination of Nicotine in Tobacco Concrete by Gas Chromatography

  • 摘要: 为准确测定烟草浸膏中烟碱含量, 以2-甲基喹啉为内标建立了测定烟草浸膏中烟碱的气相色谱-氢火焰离子化法(GC-FID), 并测定了5个烟草浸膏样品. 结果表明, 方法的回收率为95.00%~98.58%, 检出限为0.27 mg/g, 定量限为0.89 mg/g. 所测烟草浸膏中烟碱的质量分数在19.66~54.97 mg/g之间. 方法简单、灵敏、准确, 适用于烟草浸膏中烟碱的测定.

     

    Abstract: A gas chromatography-flame ionization (GC-FID) method has been developed for the determination of nicotine in the tobacco concrete using 2-methylquinoline as the internal standards, five tobacco concrete samples were determined. The results showed that the limit of detection and limit of quantitation were 0.27 mg/g and 0.89 mg/g, respectively. The recoveries were 95.00%~98.58%. The contents of nicotine in the samples ranged from 19.66~54.97 mg/g. The method is easy, sensitive and accurate, and is suitable for the determination of nicotine in the tobacco concrete.
