WebRefractive index measurement checks the purity and concentration of liquid, semi-liquid and solid samples. Refractive index values can also be determined for gases. When using a digital refractometer, liquids and semi-liquid samples can be measured with high accuracy (e.g. down to - / + 0.00002). WebIn simplistic terms, the index of refraction describes how light passes through a medium. The angle of refraction as light passes through the coffee ( i.e., how the light bends when passed through the solution) is often captured by a photodetector and the resultant refractive index calculated. navy federal credit union payoff number https://yangconsultant.com
