Instrument technology and applications of modern fourier transform near infrared spectrometer

It is the one leap on the NIR instrument technology that the Fourier Transform technology was applied to the NIR instrument. The applications of NIR analysis have been extended from quality analysis of agriculture, and food to the QA/QC and on line analysis in the petroleum chemistry, pharmaceutical, polymer, tobacco, microorganism ferment, and textile.The importance of the NIR analysis has been regarded and it will become the mainly means of QA/QC in these fields.The development of FT-NIR instrument and its advantages, the basic theory of NIR analysis and the applications of NIR analysis in production and research have been introduced in this article.
