Small angle scattering (SANS)

To investigate large structures

SANS enables investigation of micro- and nanostructures between 0,5 nm and 1000 nm. Biomolecules and other polymers, but also filter materials, alloys or catalysts possess differences in density, concentration or magnetisation over the whole sample volume.

These differences can be visualised by small angle scattering, since they divert the initially parallel neutron beam in a characteristic way. The result is information about the average particle size and their distribution, but also about shape and chemical structure of nanomaterials. Even fast kinetic processes are accessible by this method.
