what is nir

NIR stands for Near-Infrared Spectroscopy, which is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm) . NIR spectroscopy is an absorption spectroscopy method that helps determine the chemical composition of a compound or solution by measuring how much near-infrared radiation the compound or solution absorbs. NIR spectroscopy is used in a variety of scientific and industrial applications, including medical and physiological research, quality control during the production of beverages, and routine analysis of food and agricultural products. NIR can be used as a quick screening tool for possible intracranial bleeding cases by placing the scanner on four locations on the head. NIR is particularly capable when it comes to identifying and/or measuring organic compounds that feature hydrogen bonds in their molecular structure.
