采用便携式近红外矿物分析仪鉴别注胶翡翠

目前，采用传统的中红外光谱技术鉴别不透明注蜡与注胶翡翠有一定的难度。采用便携式近红外矿物分析仪检测鉴定了翡翠、注蜡与注胶翡翠样品，对其近红外反射光谱进行了分析与研究，同时对微透明样品作了中红外透射光谱的比对测试。研究结果表明，采用BJKF-1型便携式近红外矿物分析仪，能获得较好的透明或不透明翡翠、注蜡与注胶翡翠样品的近红外反射光谱，三者的近红外光谱特征存在着明显的差异。利用这些特征可有效地鉴别翡翠、注蜡翡翠与注胶翡翠。

Identification of Injection-Plastic Jadeite Jade by Portable Near-Infrared Mineral Analyser

At present, it is difficult to identify the opaque injection-wax and injection-plastic jadeite jades with the traditional midnfrared spectrum method. The jadeite jade, injectionwax and injection-plastic jadeite jade samples are tested and their nearinfrared reflectance spectral characteristics are analysed by using the portable near-infrared mineral analyser（PI- MA）. The testing comparison of the mid-infrared transmission spectra of the semitranslucent samples is also conducted. The results show that the near-infrared reflectance spectra of the transparent or opaque jadeite jade, injection-wax and injection-plastic jadeite jade samples could be acquired by using the PIMA（BJKF-1）. And these spectral characteristics are significant differences among the three, which could be used to identify the jadeite jades, injectionwax and injection-plastic jadeite jades.
