What is NIRS?
NIRS, or Near-InfraRed Spectroscopy, 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 roughage, raw materials, soil and manure samples. This brochure explains how the NIRS-technology works.
Near-infrared light is light with a wavelength between 800 and 2,500 nanometers. In the electromagnetic spectrum, the near-infrared region lies between visible and infrared light. People cannot see near-infrared light, but they can feel it as heat. Near-infrared light has the advantage that relatively little light is absorbed, making it possible to analyse samples directly without dilution or other pretreatments.
