An optical apparatus designed for the mapping of binary or ternary phase diagrams is described. A polychromatic polarized light illuminates a sample and the rotation of its polarization is measured with a spectrometer for various magnetic fields. The measured parameters are the natural and magnetic rotatory power of the sample which allow the concentration retrieval of every compound to be done. Results show that the apparatus is suitable for correct positioning of single phase boundary on the ternary water - n-dodecyl-β-d maltoside - sodium chloride system.
