Determination of the refractive index increment dn/dc - Homepage WEE-Solve GmbH

The refractive index increment dn/dc is the dependency of the refractive index to the concentration. The measuring value is needed in many areas, e.g. for the evaluation of light scattering measurements, for the determination of the sedimentation in ultracentrifuges, and for the determination of diffusion.

For these applications the preciseness of an Abbe-Refractometer is often not adequate enough. Therefore we use a precision differential refractometer, which was developed by O. Bodmann.
