Process refractometry provides an excellent method to determine the concentration of compounds (dissolved solids, proteins, chemicals) in a liquid or paste-like substance. By using the refractive index, industrial refractometry supplies real-time, accurate data to process control systems for higher quality and more efficient production. Some specific industries finding the use of industrial, inline refractometers of high value are:
Process refractometry enables real-time monitoring and control of a process based on the comparison of a known or "control" sample of a media's desired concentration, versus the value of the product moving through the production line. Industrial refractometry measures the concentration of compounds in a process media by determining it's refractive index and it’s temperature. The actual measurement is done by monitoring the refraction of light as it passes through the process media. At a certain "critical" angle of incidence, the source light is reflected rather than refracted. This critical angle can be correlated to the properties of the process media, and provides a marker that is used to determine a standard for the desired production output. By knowing this variable, at a known temperature, the concentration of specific compounds in the process media can be calculated and precisely controlled.
The use of
inline refractometers for determining concentrations of in solutions provides a fast, accurate measurement and response for process optimization and quality achievement. They dramatically lower cost by improving consistency, reducing waste, and increasing yield.
