Abstract
The headspace gas chromatography was used to determin the ethanal content in the production process of bottle grade PET chip.The optimization of headspace determination parameters such as mass,sample preparation,grain finness,heat equilibrium time,heat equilibrium temperature,calibration etc were discussed.
