6.00A 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 the concentration to be determined using mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation. The most common refractometers are handheld, analog instruments. The sample is placed on a cover plate and a prism and then held to the light to view the scale .
