Abstract

Raman spectroscopy combines the fingerprinting advantage of mid-JR spectroscopy with the ease of use and remote, non-invasive capability of near-JR spectroscopy. Now, Raman spectroscopy is fast becoming a perfect technique of analysis in raw material identification, verification, process control in biological, chemical and industrial fields, because Raman spectra are a fingerprint for the molecular species present in a specimen and can be used for both qualitative identification and quantitative determination. This paper introduces that low-resolution Raman spectroscopy (LRRS) satisfies the need for a highly useful, low-cost spectroscopic approach to both qualitative and quantitative analyses. First the principles and methods of analyses were introduced, especially quantitative analyses based on ratio method, and then several applications were described, which were representatives of qualitative and quantitative analyses. Secondly, these experimental results were discussed and analyzed in detail. The results show that the Raman spectroscopy technology is flexible, affordable and easily adapted to on-site and in situ analysis.
