Near-infrared (NIR)

Near-infrared (NIR), is a region of the infrared spectrum of light used for Near-infrared spectroscopy

Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). Typical applications include medical and physiological diagnostics and research including blood sugar, pulse oximetry, functional neuroimaging, sports medicine, elite sports training, ergonomics, rehabilitation, neonatal research, brain computer interface, urology (bladder contraction), and neurology (neurovascular coupling). There are also applications in other areas as well such as pharmaceutical, food and agrochemical quality control, atmospheric chemistry, combustion research and astronomy.

NIR is the commonly used term for Near InfraRed spectroscopy, an analysis technique which has been used in the food and agricultural industries since the late 1970s. Over the years it has become very widely adopted worldwide, as it offers signification benefits over the chemical analysis methods it replaces.

Faster – NIR gives results in seconds rather than hours
Lower cost – Much less manpower is required, no chemicals are used, and one instrument can determine multiple parameters in a sample
Easier to use – It only takes a few minutes to learn how to operate an NIR instrument, and analysis can be performed confidently by plant personnel and temporary workers.
