Near Infra Red Spectroscopy: A Growing Technique in Material Analysis

Near infrared spectroscopy is a technique with tremendous potential in coming days. The method uses near IR radiations for analysis of any kind of material, (transparent or opaque) clinical, pharmaceutical, agricultural, industrial, food and paint etc. However because of weak and broad bands, this technique has not been used routinely as a spectroscopic technique. So much work has been carried out on this technique to study its usefulness in different kind of samples and found very effective and economic for the said. Interpretation of NIR data is somewhat complicated than IR data and requires thorough knowledge of vibrating molecules. This article may help in opening the gateways and promoting the readers toward the use of NIR technique in pharmaceutical analysis.
