SAXS

Combined small- and wide-angle X-ray scattering system (SAXS/WAXS) suitable for microstructural characterization of the system containing nanoparticles, amphiphilic self-assemblies, microemulsions, emulsions, liquid crystalline phases, proteins and peptides, polymers, fibers and thin solid films with mesoscale length scales of 0,2 nm and 300 nm (USAXS: 5 µm).

The system is equipped with a high flux X-ray source, point collimation system, 2D detector, flexible control system and basic data reduction software. The system provides data with high angular resolution in a wide q-range and absolute intensity measurements.

The sample stage/environment can handle many different types of samples including liquids, pastes, gels and solids, within a wide temperature range. It is equipped with a low-noise flow-through cell for liquids. Samples can be examined in vacuum or under ambient pressure.
