Refractometry is generally speaking the measurement of refractive index and its interpretation under different starting points.
Refractometric measurements can be used for example for purity investigations, sample recognition, dilution control or composition. It’s also used for characterization of substances or for determination of substance data, especially of organic liquids.
Application areas of refractometers
An important area of application is the food-analysis. For example the investigation of oils or fat, sugar and sugar containing substances. Also beer and spirituous beverages belong to the material class, which are investigated by refractometry as well as clinical chemistry. Furthermore, refractometers are used as universal detectors in the investigation of liquids.
Inline Process Refractometer
Inline Process Refractometers measure the refractive index continuously and in real time, thus determining the concentration of liquids or the mixing ratios of binary or quasi-binary mass ratios.
The measurement is independent of turbidity, color, absorption and viscosity, which ensures maximum precision and better process control.
