Polarimetry

Certain substances turn the plane of polarized light. How can a polarimeter measure the angle of rotation or determine the concentration of the substance? How are polarimeters and their automated applications used for standards-compliant measurement methods?

What is a polarimeter?

Polarimetry will provide information about the molecular structure, the concentration of the substance and sometimes information about the solvent used. The optical activity is also influenced by temperature, the wavelength of the light, and the length of the optical path - the longer the path of the light through an optically active substance, the larger the angle of rotation. These variables may be used to control the sensitivity of the instrument.

Polarimeter applications

The angle of rotation allows you to ascertain the identity and quality of substances as well as their concentration in mix tures. It can also indicate the progress of reactions and conversions. Polarimeters are used in a wide range of applications – from the determination of the purity and concentration of ngredients in pharmaceuticals to the maturity testing of agri cultural products to the measurement of the sugar con tent in beverages and candies.
