Near Infrared Spectroscopy: Applications In Pharmaceutical Industry

This work explores the comprehensive development of a near infrared (NIR) spectroscopic analytical technique for high-throughput applications for the determination of pharmaceutical raw materials and excipients in a pharmaceutical formulation. Advancements in the NIR spectrometry as quality and process control tool have been discussed. The applications include analyses of different types of samples, manufacturing and identification of active pharmaceutical ingredients based on specified experimental design. The samples were measured in diffusion or reflectance mode in a fourier-transform NIR spectrometer. Additionally, chemometric software was employed for quantitative interpretation of bands. The spectrometry can be utilized for identification of raw materials, their size, polymorphism and blend homogeneity
