SAXS

Small angle X-ray scattering (SAXS) is a powerful and nondestructive method for analyzing nanostructure materials. The technique yields information such as particle sizes and size distributions from 1 to 100 nm, including shape and orientation distributions in liquid, powders and bulk samples. Applications range from life science and biotechnology (proteins, viruses, DNA complexes) to polymers, emulsions, liquid crystals, fibers and catalysts.

SAXS

Small angle X-ray scattering (SAXS) is a technique for studying structural features of colloidal size. It is performed by focusing a low divergence X-ray beam onto a sample and observing a coherent scattering pattern that arises from electron density inhomogeneities within the sample.

Since the dimensions typically analyzed are much larger than the wavelength of the typical X-ray used (1.54 Å, for Cu), dimensions from tens to thousands of angstroms can be analyzed within a narrow angular scattering range.

This angular range or pattern is analyzed using the inverse relationship between particle size and scattering angle to distinguish characteristic shape and size features within a given sample.
