17.3: Particle Size Measurement by Light Scattering

WebbSmall angle neutron scattering is in many respects very similar to small-angle X-ray scattering (SAXS); both techniques are jointly referred to as small-angle scattering (SAS). Advantages of SANS over SAXS are its sensitivity to light elements, the possibility of isotope labelling, and the strong scattering by magnetic moments. Webb8 nov. 2024 · Back angles minimize the effect of any residual and unwanted larger particles (dust, large aggregates or impurities). Small angles maximize the effect of these larger scatters.
