Rigaku NANOPIX mini

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.

Nanoparticles in consumer and industrial products
Nanomaterials offer technical and commercial opportunities, but may pose risks to the environment and raise health and safety concerns for humans and animals. As such, countries around the world have enacted increasingly stringent laws concerning the manufacture and distribution of nanomaterials. The Rigaku NANOPIX mini SAXS instrument offers unique analytical capabilities, relative to other particle measurement techniques – including the ability to measure opaque and solid samples – that offer superior data quality for regulation-driven nanoparticle characterization in consumer and industrial products.

NANOPIX mini offers unique capabilities
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.

NANOPIX mini Applications

NANOPIX mini for filler particles in resins, rubbers and plastics

Use of particulate fillers to modify the mechanical properties of resins and rubbers is well documented. The filler modifies not only the mechanical properties of resins but also the physical and chemical properties such as melting temperature and electric resistance and so on. Some fillers, particularly those of very small particle size, reinforce polymers. Strength enhancement depends principally on the particle size of the filler, increasing with decreasing particle size. NANOPIX mini is the ideal instrument for quantifying filler particle size and size distribution in optically opaque samples like rubber where other methods are cumbersome. Shown at right is data from rubber samples with different monodisperse filler particle sizes showing clearly distinct scattering patterns....

NANOPIX mini for particle size and distribution

SAXS is a powerful method to determine both average particle size and size distributions. The plots show experimental data from silica nanoparticles as measured by the NANOPIX mini. The plot (below) shows the 1D SAXS pattern of measured intensity as a function of 2θ angle. NANOPIX mini software evaluates the 1D SAXS pattern (left side) and calculates the volume-weighted particle size distribution (right side). The average diameter is estimated to be 111 nm, which agrees with TEM image analysis.
