Abstract

Various analytical techniques are available nowadays to quantify a substance in a sample. These techniques are based on the quantitative performance of suitable chemical reaction, the characteristic movement of a substance through a defined medium under controlled conditions, electrical measurement, and the measurement of some spectroscopic properties of the compound. Fourier transform infrared (FTIR) spectroscopic imaging with infrared array detectors has recently emerged as a powerful materials characterization tool. IR spectroscopy is a significant technique which utilizes electromagnetic radiations in the infrared region for the determination and identification of molecular structure. Infrared (IR) spectroscopy is one of the oldest and well recognized experimental techniques for the examination of proteins, food stuffs, dyes, pharmaceutical formulations, etc. In this paper, authors have compiled various quantitative applications if infrared spectroscopy for determination of pharmaceutical suspension formulations, determination of lipids and fatty acids in food stuffs, determination of dyes, etc.
