What is Near Infra-Red Spectroscopy ( NIR)
Near Infrared Spectroscopy is a spectroscopy technique that utilises the electromagnetic spectrum from approximately 700nm to 2500nm.
Typically NIR techniques require a light source, dispersive element such as a prism or linear variable filter and a detector. Absorption of the NIR region is cause by molecular overtones and combination vibrations of organic molecules.
Using chemometric techniques chemical and physical processes can be monitored in near real time.
