Principle of Polarimeter
The working principle of a polarimeter is based on measuring the optical rotation of a sample tube containing the solution under test. By measuring the optical rotation of the sample, it is possible to analyze and determine the concentration, content, and purity of substances. Polarimeters are widely used in pharmaceuticals, drug testing, sugar production, food, fragrances, monosodium glutamate, as well as chemical and petroleum industrial production.
The optical rotation of a substance primarily depends on its molecular structure. Additionally, it is influenced by the thickness of the material through which light passes, the wavelength of light used for measurement, and the temperature. If the substance being measured is a solution, influencing factors also include the concentration of the substance, and the solvent may also have some effect. Therefore, the optical rotation of a substance often varies under different conditions.
