Why Measure the Refractive Index?

摘要

The refractive index of a pure material is a physical property which you can use to identify and characterise samples. For binary mixtures, e.g. dissolved substances, the refractive index is a measure of concentration. For ternary or multi-component mixtures of a given mixing ratio, you can monitor the refractive index for quality control. As refractive index measurements are quick and reliable, the method is the state of the art in industries around the globe. Measuring refractive index is an essential part of numerous standard operating procedures and laboratory.analyses.
