NIR and SWIR spectroscopy play an essential role in factory, farm and food processing and are a valuable source of information in the toolkit of physical scientists. They unlock a deeper understanding of materials and their properties. With their ability to provide non-destructive and real-time analysis, these techniques have revolutionised ...
NIR spectroscopy is a technique that uses near-infrared light to analyze the composition and properties of substances. It is widely applied in various fields such as chemistry, biotechnology, pharmaceuticals, and food engineering.
Additionally, NIR spectroscopy is applicable to both organic and inorganic compounds, enabling its use in diverse areas. The instrumentation for NIR spectroscopy typically consists of a light source, which emits NIR radiation, a sample holder or cuvette, and a detector that measures the intensity of the transmitted or reflected light.
NIR spectroscopy is a technique that measures the interaction between light and matter in the near-infrared region. It can be used to analyze chemical and physical properties in solids and liquids without sample preparation. Learn more about the methods, advantages, and applications of NIR spectroscopy.
FT-NIR spectroscopy is a fast, inexpensive and safe analysis method that uses the NIR region of the electromagnetic spectrum. Learn how it works, what are its benefits and how to measure different types of samples with various probes and accessories.
NIR spectroscopy is an absorption spectroscopy method that measures how much near-infrared radiation a compound or solution absorbs. Learn how NIR spectroscopy works, how it differs from UV-Vis spectroscopy, and what industries use it for chemical analysis.
NIR imaging is a combination of NIR spectroscopy with digital image processing. A NIR imaging system is basically composed of an illumination source, an imaging optic, a spectral encoder selecting the wavelengths, and a focal plane array (FPA) as indicated in Fig. 7. NIR light from an illumination system is focussed upon the sample.
