Refractometer report card
Concentration is an important final quality parameter. Refractometers work in many industries and are a quick, effective way of measuring concentration. Their application requires only that the measured component be a dissolved solid or miscible liquid into another solution.
Refractive index measurements of liquids, which have traditionally happened in the lab, are taking place in the process environment. The process measurement of refractive index is now reliable, simple, and cost effective.
An in-line process measurement of refractive index works as a real-time predictive tool for the final concentration, viscosity, and other process parameters. The speed of response enables production optimization.
Cost reduction is possible by reducing the variation of the mean average product concentration and depends on the component’s value.
