电感耦合等离子体质谱法测定口含烟中的钠

Determination of Sodium in Snus by Inductively Coupled Plasma Mass Spectrometry

  • 摘要: 建立了电感耦合等离子体质谱仪(ICP-MS)测定口含烟中钠的方法,并对影响测定结果的主要因素进行了优化.结果表明,方法检出限和定量限分别为0.553 4和1.845 μg/Kg,平均回收率为92.00%~97.63%,RSD低于5.535%(n=6).应用方法对不同品牌的口含烟样品进行了检测,结果显示,不同品牌口含烟中钠含量水平差异明显.

     

    Abstract: A method was developed to determine sodium in snus by inductively coupled plasma mass spectrometry(ICP-MS), the main factors affecting the determination were optimized. The results showed that, the detection limit and the quantification limit of sodium was 0.553 4 and 1.845 μg/Kg, respectively, the average recovery rate of this method was 92.00%~97.63%, with the relative standard deviation values below 5.535% (n=6).This method was applied to determine products of different brands, the results showed that the difference of sodium amount among different brands was obvious.
