What is volume distribution?
Fundamental size distribution generated by Dynamic Light Scattering (DLS) is an intensity distribution that can be converted to a volume distribution (relative proportion of multiple components in the sample based on their mass or volume vs scattering intensity) using Mie theory. This assumes:
- All particles are spherical
- All particles are homogeneous
- Optical properties of particles are known (the real & imaginary components of the refractive index)
- Accurate intensity distribution
