Refractometry is the analytical method of measuring a material’s refractive index. The refractive index is a value specific to a material and is dependent on temperature and wavelength (λ = colour) of the light. Thus, if temperature and wavelength are known, a refractometer allows you to determine the concentration of a material.
SciMed offers a comprehensive range of refractometers from Schmidt and Haensch, a Berlin based company founded 1864. Schmidt and Haensch are at the forefront of development of analytical methods in the sugar industry and are responsible for many of the improvements in methods through innovative design solutions. The range of refractometers provide a solution to every requirement from simple sugar concentrations to comprehensive studies of a compound’s refractive index properties.
Refractometric measurements are often used in quality control for purity investigations, sample recognition, dilution control or composition. They are also used for characterization of substances or for determination of substance data, especially of organic liquids.
