Refractometry theory
WebApr 14, 2024 · A refractometer is a tool that can determine the concentration of a particular substance in a liquid solution. It uses the principle of refraction, which describes how light bends as it crosses the … A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index of refraction then allows to determine the concentration using mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation.

Like a melting point, it can be used to confirm the identity of a compound, or … WebMay 6, 2016 · Theory. The refractive index is the ratio of the sine of the angle of incidence of a ray of light in vacuum to the sine of the angle of refraction in the medium, which is equal to the ratio of the wave velocity of light in vacuum to the wave velocity in the medium. The angle are measured relative to the normal of the interface between the two ...
