SAXS Software

Comprehensive SAXS Analysis

DIFFRAC.SAXS sets a new benchmark for Small Angle X-ray Scattering (SAXS) software. Interpretation of 1D and 2D SAXS data has never been easier, faster and more accurate. DIFFRAC.SAXS combines an extensive collection of modern and powerful algorithms for data processing and evaluation with a work-flow that is simple and flexible. Seamless integration of each step in the visualization, data reduction and analysis process ensures ease of use and accurate results. Many operations can run automatically to maximize throughput, or interactively for ultimate control.


DIFFRAC.SAXS has different data analysis routines onboard, including model-free as well as model-based methods, to cope with the huge diversity of nanomaterials.

DIFFRAC.SAXS features an easy-to-use user-interface, advanced graphics and customizable analysis report. An extensive step-by-step tutorial considerably shortens the learning curve. The tutorial and extended user manual also serve as excellent tools to introduce newcomers to SAXS analysis, getting them started in the shortest time possible.
