Near-InfraRed Spectroscopy or NIRS is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 800 - 2500 nm). Karl H. Norris developed this technique in the 1960s, in order to analyse agricultural products in particular.
Eurofins Agro uses NIRS for the analysis of forage, raw materials, soil and manure samples.
NIRS is a useful analytical technique due to the fact that different molecules absorb and reflect near-infrared light to different extents. When molecules absorb energy from near-infrared light, this energy is converted into kinetic energy. As a result, the atoms within the molecules move faster, bending, stretching or rotating alongside one another. The more light that is absorbed by molecules, the less light that is left to be reflected.
Near-infrared light is light with a wavelength between 800 and 2,500 nanometers.
