Abstract
A device is disclosed for determining characteristic parameters of the dimensions of nanoparticles in suspension in a liquid. The device emits an incident light beam that is linearly polarized along a polarization axis; a detecting unit comprising a measurement arm that is rotatable with respect to an axis of rotation, the detecting unit comprising first and second detection channels that are separated by a polarization-splitting element arranged in the measurement arm; a fixed sample holder receives a container of cylindrical symmetry of the sample, an axis of symmetry of the container being coincident with the axis of rotation of the measurement arm; and a control unit. The polarization-splitting element of the measurement arm is configured to simultaneously send, over each of the first and second detection channels, respectively, a first and second polarized component of the beam scattered by the sample.
