摘要
近红外光谱是 2 0世纪 90年代以来发展最快、最引人注目的光谱分析技术。阐述了近红外光谱的原理、技术特点 ,介绍了近红外光谱仪、光谱预处理方法以及化学计量学研究的发展过程 ,重点列举了近红外光谱在农业和食品分析中的成功应用实例。资料表明 ,近红外光谱以其速度快、不破坏样品、操作简单、稳定性好、效率高等特点 ,已广泛应用于各个领域。特别是在欧美及日本等发达国家 ,很多近红外光谱分析法被列为标准方法。而我国近红外光谱的应用研究起步较晚 ,虽然某些方面已具国际领先水平 ,但就总体来看与国际水平还有大的差距。文章首次提出了集中优势资源 ,包括人力资源和设备资源 ,利用现代网络技术 ,建立终端用户和中心数据库资源共享的模式 ,以推动近红外光谱技术在我国农业科技和生产中的应用。
Near-Infrared Spectroscopy (NIRS) is the most rapidly developing and the most noticeable spectrographic technique in the 90's(the last century). Its principle and characteristics were explained in this paper, and the development of NIRS instrumentation, the methodology of spectrum pre-processing, as well as the chemical metrology were also introduced. The authors mainly summarized the applications to agriculture and food, especially in-line analysis methods, which have been used in production procedure by fiber optics. The authors analyzed the NIRS application status in China, and made the first proposal to establish information sharing mode between central database and end-user by using network technology and concentrating valuable resources.
