X-ray scattering measures the patterns, intensities, and angles of scatter produced when a sample is illuminated by an x-ray beam. X-ray scattering is advantageous as it is a non-destructive technique, typically used alongside x-ray microscopy and x-ray spectroscopy. Information on shape, dispersity, sample size, porosity, morphology, and orientation are some of the few things that can be measured via x-ray scattering.
X-ray scattering can be elastic, or inelastic. There are different x-ray scattering techniques, the most common being x-ray diffraction/crystallography. This technique relies on the crystalline structure of a sample, and typically needs very high energy hard x-rays to obtain atomic level information.
Other techniques include small-angle x-ray scattering (SAXS) and wide-angle x-ray scattering (WAXS). X-rays can be elastically scattered at a range of different angles dependent on the sample. In this way, the angle of the scattered x-rays can give information on the physical properties of a sample. SAXS provides nanoscale resolution, whereas WAXS provides atomic resolution. Both techniques can be done simultaneously by increasing or decreasing the space between the detector and sample.
