SAXS GISAXS
General information
Xenocs XEUSS 3.0 system operates in SAXS (Small Angle X-ray Scattering), USAXS (Ultra SAXS) and GISAXS (Grazing Incidence SAXS) modes. It is equipped with sample holders for measurements on powders, pastes, gels, liquids and films, temperature control and robot for automation of sample preparation.
Technical description
Xenocs XEUSS 3.0 system operating in SAXS (Small Angle X-ray Scattering), USAXS (Ultra SAXS) and GISAXS (Grazing Incidence SAXS) modes, equipped with sample containers for powders pastes, gel, liquids and thin films, temperature control and automated sample preparation for liquid sample via a Universal Robot. The scattering wavevector range for U/S/WAXS is between 0.0002 and 3.1 Å-1.
Research areas and applications
The system allows for studying (fr instance):
- Particle size distribution ranging from few nanometers to more than 350 nm in diameter
- Crystallization rates and lamellar structure of semicrystalline polymers
- Size and shape analysis of surfactants or proteins in solutions
- Organization and orientation of nanomaterials at atomic or nanoscale, in bulk phases or at surfaces
- Phase segregation studies of alloys
- In situ studies of nanostructure transitions
