| Abstract: | Objective:To establish a method for determination of residual organic solvents in composite laminated food packaging bag by head-space gas chromatography.Methods:The volatile part of sample was balanced by head-space gas chromatography and determined by GC.Results:The twelve kinds of solvents were absolutely separated.Determination limit was between 0.006 and 0.020 mg/m2,the recoveries between 90.1% and 98.4%,RSD between 2.07% and 3.22%.Conclusion:The proposed method has been applied to analyze samples for the residual organic solvents.The samples is separated better and quickly. |
