    • Non-technical operation for routine particle size distribution determinations
    • Delivers nanoparticle characterization needed for regulatory compliance
    • Perfect for opaque suspensions not easily addressable with other techniques
    • Suitable for use with solids – like plastics, rubbers and polymers
    • Compact benchtop design with a small countertop footprint
    • Innovative design using proven components for low cost of ownership
    • Automatic sample changer for higher throughput
    • New easy-to-use SmartLab Studio II SAXS software
    • Touchscreen graphical user interface operation
    • Compact Bonse-Hart USAXS camera design


Rigaku NANOPIX mini is the world’s first benchtop small angle X-ray scattering (SAXS) system that is engineered to deliver automatic nanoparticle size distribution analysis for both quality control (QC) and research and development (R&D) applications. Nanoparticle size, size distribution, and particle shape are the key pieces of information obtained from SAXS. Samples may range from solutions, suspensions or slurries to solid plastics, rubbers or polymers.

Rigaku NANOPIX mini is the first benchtop small angle X-ray scattering system dedicated to the characterization of nanoparticles in both research and production environments. With a revolutionarily small footprint and performance superior to traditional “big iron” systems, this compact instrument offers enhanced angular resolution through its line-focus X-ray source and superior combination of high figure-of-merit optics.
