    Head Space-GC Determination of Residual Solvents in Cigarette Adhesive

    • 摘要: 采用顶空气相色谱法对卷烟粘合剂中11种溶剂残留化学成分进行标准加入法检测分析.采用DB-624毛细管色谱柱(30 m×0.32 mm,0.25 μm)分离,用火焰离子化检测器测定.在优化的柱温和顶空条件下,11种残留溶剂的测定下限(10S/N)均低于0.5 μg·g-1,相对标准偏差(n=6)在1.8%~3.3%之间.甲醇、异丙醇和苯三种溶剂的回收率在94.4%~107.7%之间.

       

      Abstract: Residual amounts of 11 solvents in cigarette adhesive were determined by head space-GC with standard addition method.The DB-624 capillary column (30 m×0.32 mm,0.25 μm) was used as separation column,and FID was used in the detection.Under the optimum column temperature and head space condition,the detection limits (10S/N) of 11 residual solvents were less than 0.5 μg·g-1,with RSD′s (n=6) in the range of 1.8%-3.3%.The values of recovery of methanol,isopropanol and benzene found were in the range of 94.4%-107.7%.
