Abstract

In a method for achieving improved refractometric analysis of a medium, comprising determination of the wavelength of light corresponding to a specific refractive index of said medium, wherein the performance of the measurement is improved through modification of the refractive index dispersion of the medium. In one aspect of the invention, the sensitivity of the method is improved by decreasing the refractive index dispersion of the medium as detected by the refractometer. In another aspect of the invention, the measurement range of the method is increased by increasing the refractive index dispersion of the medium as detected by the refractometer.
