紅外光譜仪用于記录物貭的紅外吸收光譜,可以鑑别其分子結构,它是物理学、化学特別是高分子化合物上作分子結构研究的主要和广泛应用的仪器。此外,它还应用于生物学、医学等方面的研究。近年来随着技术的进展,在工业先进的国家,这种仪器已成为有机化学工业(石油、塑料、橡胶、制药等)进行定性分析和定量分析的現代化工具。它不仅能測定物貭在工艺过程中成分上的变化,而且能表示出其結构上的变化,为一般的化学分析方法所不及。世界上只有工业先进的几个国家制造自动記录紅外光譜仪。中国科学院光学精密机械仪器研究所在1958年大跃进的基础上,提出了光、机、电全面結合的紅外光譜仪研究試制工作。仪器設計采用了現代的双光路比較法原理。光学系統参照一些国际現有仪器
Infrared spectroscopy is used to record the infrared absorption spectrum of the object, which can identify its molecular structure. It is the main and widely used instrument for the study of molecular structure in physics, chemistry, especially for polymer compounds. In addition, it is also used in biology, medicine and other aspects of the study. In recent years, with the progress of technology, in advanced countries, such instruments have become the modern tools for the qualitative analysis and quantitative analysis of the organic chemical industry (petroleum, plastics, rubber, pharmaceuticals, etc.). It can not only determine the change of composition in process, but also show the structural change, which is beyond the normal chemical analysis methods. There are only a few countries in the world that have advanced industries to make automated recording IR spectrometers. On the basis of the Great Leap Forward in 1958, the Institute of Optics, Fine Mechanics and Instrumentation, Chinese Academy of Sciences put forward the trial production of the infrared spectrometer with full integration of light, electricity and electricity. Instrument design uses a modern dual-path comparison principle. Optical system reference to some of the existing international instruments
