Small-angle X-ray scattering is a method by which investigators can identify materials and obtain qualitative and quantitative information on their abundance and physical properties. This instrument has a setup to perform small- or wide-angle X-ray scattering on freestanding samples, powders prepared in various tapes, liquids in capillaries and gels in paste cells with transparent windows. In addition, the machine is equipped with Grazing-incidence small- and wide-angle scattering (GISAXS and GIWAXS).
