摘要
论述了瓶级聚酯切片生产过程中,采用顶空气相色谱法测试切片中乙醛含量的称样量、样品处理、颗粒度、顶空热平衡时间、热平衡温度、标定及其他顶空测量参数的优化。
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.
