ABSTRACT:
A method for the measurement of the concentration of a material such as dextran or raffinose in a solution, notably a sugar solution, includes the steps of measurement of the optical rotation of a solution sample, treatment of the sample with a reactive agent, measurement of the optical rotation of the sample after treatment to ascertain the difference that said treatment has made, and calculation of the concentration of the material by reference of said difference to a suitable standard. The reactive agent reacts with the material sufficiently to alter the optical rotation of the sample.
