Small Angle X-ray Scattering (SAXS) is a technique particularly suited for the structural investigation of partially ordered materials, usually applied to condensed matter systems. SAXS provides information about larger scale bulk microstructure within a sample, usually in the size range from approximately ~1nm up to around 300nm.
The high intensity X-rays available at a synchrotron provide two chief benefits over lab-based instruments.
SAXS can be applied to systems that are either difficult or impossible to crystallise, may be complex or composite systems or materials with large scale self-organisation. Due to the wide range of sample types, SAXS has been employed in a wide range of applications from drug delivery systems and protein solution shape analysis through to formulations, phase behaviour, catalysis, advanced materials development and engineering.
USAXS is a subset of SAXS and a member of the larger X-ray scattering techniques family. USAXS means Ultra-Small Angle X-ray Sacttering where by the smaller the angle recorded, more information about the larger structure can be determined.
