8 Q&A About Polarimeters – You Must Know
A polarimeter is an instrument for measuring the optical rotation of an optically active substance. By measuring the optical rotation of the sample, the concentration, content, and purity of the substance can be determined by analysis. Principle of Polarimeter Plane-polarized light is generated after natural light passes through the polarizer. If the optically active material is…
