Everything about Refractometry
Refractometry is the analytical method of measuring substances' refractive index in order to, for instance, assess their composition or purity. A refractometer is the instrument used to measure refractive index ("RI"). Although refractometers are best known for measuring liquids, they are also used to measure gases and solids, such as glass and gemstones. Wikipedia →
