METHOD FOR MEASURING A PARTICLE SIZE DISTRIUTION OF A POPULATION OF PARTICLES

摘要

The present invention provides a method 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 method 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).
