Size and Size Distribution of Gold Nanoparticles by SAXS
Size and Size Distribution of Gold Nanoparticles by SAXS
2 Nov 2015Many materials gain their properties from the grain size of their constituting particles. Examples are the activity of catalysts and enzymes, the mechanical stability of ceramics and the thermal, electrical and optical properties of nanoparticles. Aggregate formation and imperfect redispersion may lead to an effective particle size in suspension much larger than the primary particle size. Coalescence is one of the main break-down processes in emulsions. This application note demonstrates the measurement of Gold nanoparticle dispersions by the SAXSpace system. SAXS proved to be a well-suited method for determining the size distribution of a binary mixture of two dispersions with very similar particle size.

Modular System for Nanostructure Analysis: SAXSpace
Anton PaarSAXSpace is a new nanostructure analyzer for small- and wide-angle X-ray scattering (SWAXS) studies of nanostructured materials. With its easy handling and push-button alignment, SAXSpace is ideally suited for routine SWAXS analysis and quality control applications. SAXS experts benefit from the spacious sample chamber and versatile sample stages, allowing for full experimental flexibility. This makes SAXSpace an ideal tool for investigating nanostructures in many different materials, including nanoparticles, biological macromolecules (Bio-SAXS), nanostructured surfaces (GI-SAXS), polymers and pharmaceuticals.
