FTIR-OMNI采样器在皮革产品鉴别中的应用研究

Study on Application in Identification of Leather Products by FTIR-OMNI Sampler

采用傅里叶变换红外光谱仪的衰减全反射附件——OMNI采样器,对国家部分标准皮革样品及市售再生革样品进行了红外光谱分析。结果表明:牛、山羊、猪、马等天然革具有相似的红外光谱特征,天然革与人造革、合成革及再生革的红外光谱特征峰区别十分明显。该技术具有无损分析的特点,能快速准确地对真假皮革产品进行鉴别。

The infrared spectrum analysis was taken for some national standard leather samples and the reproductive leather samples from market, by the Attenuated Total Reflection accessory of the Fourier Transform Infrared Spectrometer-OMNI sampier. The results show that the natural leather samples of cattle, goat, pig and horse had the samiliar features of infrared spectrum. While the difference between the characteristic peaks of natural leather, artificial leather, synthetic leather and reproductive leather is distinctive. The technique can identify the natural leather and non - natural leather products rapidly and accurately without damaging samples.
