ABSTRACT:
The present invention provides for measuring a particle size distribution of a population of particles using a light scattering particle sizing instrument having a plurality of selectable imaginary component values of the refractive index. The particles each having a particle size and the process includes the steps of: (i) providing a population of the particles, wherein the particles have a refractive index; (ii) determining a real component of the refractive index of the particles using the Becke Line Method; (iii) determining an imaginary component of the refractive index of the particles; and (iv) determining the particle size distribution of the particles by the light scattering particle sizing instrument wherein the particle size distribution is determined using the real component of the refractive index measured in step (ii) and the imaginary component of the refractive index determined in step (iii).
