Static Light Scattering (SLS) Technology

Static light scattering (SLS) is a technology for measuring absolute molecular weight. As described in Rayleigh theory, this technology uses the relationship between the intensity of light scattered by a molecule and its molecular weight and size for molecular weight characterization. That is, under certain light source conditions, larger molecules scatter more light than smaller molecules, and the intensity of the scattered light is proportional to the molecular weight of the molecule. Static light scattering is mainly used in molecular weight determination of large molecules such as proteins and polymers.
