A method for simultaneous detection of 25 kinds of solvent residues in complex plastic film by static headspace gas chromatography has been established. The sample of complex plastic film was heated and transferred into a gas chromatograph for static headspace analysis. The separaction was performed on a DB-FFAP capillary column (60m×0. 32mm, 1.00μm). The compounds in solvent residues were detected by a FID, and their contents were calculated by internal standard method. The recoveries of different solvents were in the range of 58%～110% (spiked levels were 0. 4mg/m~3, 2. 0mg/m~3 and 10.0mg/m~3, respectively). The RSDs were 2. 66%～14. 15% and the detectionlimit was 0. lmg/m~3.
