Description
Many chemical substances are optically active and rotate the plane of polarisation of polarised light passing through. The direction of rotation and specific angle α are characteristic sizes of a substance or a solution and are measured using polarimeters. Classic polarimeters operate manually, requiring a qualified operator and a certain amount of time. Modern automatic polarimeters speed up this process – a precise measurement value is outputted in seconds. Investment in an automated instrument pays off very quickly because it significantly improves productivity in the laboratory.
