Head Space-GC Determination of Residual Solvents in Cigarette Adhesive

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%.
