Abstract

OBJECTIVE:To establish the method for determination of residual acetaldehyde in oral liquid PET bottle. METHODS:Headspace gas chromatography was adopted. The determination was performed on DB-FFAP capillary column. FID detector was used with injector temperature of 200 ℃ and detector temperature of 200 ℃ using nitrogen as carrier gas. The equilibrium temperature of headspace sampling was set at 70 ℃ with equilibrium time of 30 min by programmed temperature. RESULTS:The linear range of acetaldehyde was 0.002～0.02 mg·L-1(r=0.999 1) with average recovery of 98.37%(RSD=2.82%,n=6) . The detection limit was 0.1 ng. CONCLUSION:The method is accurate,relibale and can be used for determination of the limit of acetaldehyde in oral liquid PET bottle.
