Application of X-ray Absorption Spectroscopy with a laboratory X-ray powder diffractometer

A novel method and experimental configuration are proposed that allow the collection of high-quality X-ray absorption spectroscopy (XAS) data in transmission mode on a standard laboratory diffractometer. This configuration makes use of components that have been developed for application in modern laboratory diffractometers, such as X-ray tubes with enhanced stability, accurate goniometers and position-sensitive photon-counting detectors with improved energy resolution. Such approach may extend the application of XAS in materials research, particularly for users of diffraction methods.
