红外衰减全反射技术及其在食品软包装复合材料材质分析中的应用

Technique of Attenuated Total Reflectance(ATR)of Infrared Spectroscopy and Applications in Analysis of Soft Packaging Complex Materials of Foods

本文介绍了红外光谱法衰减全反射技术的简单原理,利用该方法鉴定了几种食品软包装复合材料,并对几种高聚物复合膜的 ATR 光谱与透射光谱进行了比较。

The principle of the technique of ATR was briefly introduced.By this method,some soft packaging complex materials of foods were identified and ATR spectra of complex film of some polymers were compared with their transmission spectra.
