Discovery of spectral polarimetry? A polarimeter is a device for determining the polarisation direction of the light or the rotation of an optically active substance. The physicist Francois Jean Dominique Arago made a discovery on quartz, which was very important for polarimetry. Arago cut a quartz crystal perpendicular to the crystal axis and saw the […]

One of the most important quality control methods used in the pharmaceutical, chemical, cosmetics, food and beverage industry is polarimetry – optically active substances are analysed by determining their angle of rotation. The angle of rotation allows you to ascertain the identity and quality of substances as well as their concentration in mixtures. It can […]
