Abstract
A new method for the determination of 17 kinds of solvent residues in the packing materials by headspace gas chromatography was established.The temperature and time for equilibration of the sample were studied,The separation was performed on a DB-WAX capillary column(60 m×0.25 mm×0.25 um). The compounds in solvent residues were detected by a FID.Results showed the temperature and time for equilibration of the sample in the head-space vessel were 110℃ and 40 min,17 kinds of solvents were separated from each other completely and the good linear range could be achieved by this method,the recoveries are 79.64%~91.78% with RSD(n=6) in the range of 2.32%~4.52%,and the limits of detection are 0.003~0.012 mg/m2,This method can be applied for determining the solvent residues in the packing materials.关键词
