Introduction
Hecus X-Ray Systems, founded in 1992, is traditionally specialized on innovative system solutions for X-Ray nanostructure analytics. The strong focus on small-angle X-ray methods - the Otto-Kratky heritage - serves a wide community of researchers and engineers, who need SAXS and related techniques as practical and reliable tools in their challenging laboratory practice, and who want to use the techniques routinely.
What is SAXS/SWAXS?
Small- and Wide-Angle X-ray Scattering (S/WAXS) are non-invasive analytical techniques to investigate the structure of non-crystalline or partly crystalline materials. Both the supra- or macromolecular domain as well as the interatomic distances in small molecules or crystals are investigated.
Fields of Application:
- Polymers
- Liquid Crystals
- Powders & Cream Formulations
- Biopolymers
- Biomaterials
- Catalysts
- Nanomaterials
- Coatings & Films
