SAXS Instrumentation

The lab is equipped with a custom designed and made 3 pinhole collimation camera. Typical applications include the analysis of nanocomposites (dispersion, nanofiller size and distribution of sizes), investigations of block copolymers, polymer blends, semicrystalline polymers, etc.
