Near infrared analysis

Near-infrared (NIR) spectroscopy is a non-destructive analytical tool that provides solutions from drug development to the QA/QC lab, and in at-line, on-line, or continuous manufacturing processes. Its potential in the pharmaceutical manufacturing value chain is still expanding. . Near-IR absorption spectrum of dichloromethane showing complicated overlapping overtones of mid IR absorption features. The interaction of infrared light (700–2500 nm) with food. . His academic credentials (AB in Chemistry from Syracuse University, an MS in Organic Chemistry from University of Puget Sound, and a PhD in Biochemistry from Purdue University) didn't prepare him for a career in near-infrared. But as a trained scientist, he recognized the potential of NIRS and, as. . Near-infrared (NIR) light refers to wavelengths from 800 to 2500 nm (12,500–4,000 cm -1). It sits just beyond visible light and is commonly used in material analysis due to its ability to measure broad overtone and combination bands of some of the fundamental vibrations.
