About SAXS
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.
Wide Angle X-ray Scattering, essentially analogous to powder diffraction, provides information about crystallisation and can be measured simultaneously with SAXS.
