Across the wide range of material and chemical production industries, demand is growing for improved quality assurance and quality control (QC) processes. As the regulation and quality requirements ...

Photons in the ultraviolet/visible spectral range have sufficient energy to ionize or excite materials by increasing the energy level of bound electrons. NIR radiation has less energy per photon but ...

In the early 1940s, the first commercial dispersive spectrometers emerged for UV-Vis applications. This technology is based on the dispersion of light in dependence of its wave-lengths. The dispersion ...

A rapid method for simultaneously quantifying glycerin and nicotine in liquid mixtures used for electronic cigarettes is presented in this article. Using visible near infrared spectroscopy (VIS-NIRS), ...

NIR spectroscopy can be used for a final quality check to make sure the beer means product specifications. Alcohol content, pH, SSC, original gravity, carbonation level, foam volume, and other ...
