Introduction to Static Multiple Light Scattering (SMLS)
Static Multiple Light Scattering (SMLS) is the most suited method to characterize liquid dispersions, directly, in their native state.
Most emulsions, suspensions, and formulations are too concentrated to be analyzed “as is” and their characterization requires dilution or mechanical stress, which alters their state and structure. Static Multiple Light Scattering (SMLS) offers the ability to investigate the dispersion state and its evolution over time, without any dilution, even on highly concentrated samples. The SMLS principle is based on a patented optical setup and measurement principle.
Static Multiple Light Scattering (SMLS) offers an extraordinary resolution to detect size and concentration variation occurring in complex formulations and in a very wide range of applications and industries. SMLS is in perfect agreement with ISO TR13097's recommendation regarding shelf-life and stability measurement as a direct optical method that does not require sample preparation (such as dilution).
