Market Profile: Near Infrared (NIR) Spectroscopy



Volume 35
Issue 2

The total market for NIR was measured at about $470 million in 2019 and is expected to reach over $570 million by 2024.

Near infrared (NIR) spectroscopy can probe material and speci­mens requiring deep sample penetration without substantial preparation. NIR is based on the absorption of photons at wave­lengths in the range 780–2500 nm and is used to measure mo­lecular overtone and combination vibrations within these ranges. As in most spectrometers, light is passed through diffraction grating to separate it into individual wavelengths through a sample to the detector. The results are a spectrum of trans­mittance at NIR wavelengths.

At first, NIR instruments were add-ons to UV-vis spectrophotometers before becoming stand-alone systems focused on chemical analysis. Now, monochromators and fiber optics have allowed NIR analyzers to be used in medical and physiological diagnostics, and in research in kinesiology, rehabilitation, and neurology. Industries have also made use of NIR analyzers for bioenergy, forestry, building materials, textiles, and quality assurance. A large portion of NIR instruments are used for food to analyze crops, meat, dairy, beverages to ascertain finished product profiles of density, moisture, protein, oils, and carbohydrates.

The total market for NIR was measured at about $470 million in 2019 and is expected to reach over $570 million by 2024. The fastest growth within this segment is from portable/ handheld NIR analyzers, which is expected to top $100 million in demand by 2024. Scanning & Diode array NIR analyzers account for the largest segment. Environmental and food industries make up over a third of demand by application in 2019 and will continue to be the fastest growing segment due to increased adoption in agriculture. Leading suppliers of NIR instruments are Bruker, Foss, and Thermo Scientific.
