ATR-FTIR结合DSC法快速鉴别食品接触用塑料包装制品

Rapid identification of plastic packaging materials for food contact using ATR-FTIR/DSC

研究了一种衰减全反射红外光谱(ATR-FTIR)结合差示扫描量热法(DSC)快速鉴别食品接触用塑料包装制品单一材质的方法。红外光谱图能准确反应塑料制品的内部结构,结合DSC曲线得出其具体成分。该方法快速、准确且几乎不破坏样品。

A method of attenuated total reflection infrared spectroscopy(ATR-FTIR)combined with differential scanning calorimetry(DSC)was investigated for rapid identification of the plastic packaging materials for food contact.Infrared spectrograms can accurately reflect the structure of plastic products,within DSC spectrogram established.This method is quickly and accurately.Furthermore,without damaging the sample.
