Abstract

The invention provides an X-ray analysis apparatus (100) and method for carrying out X-ray absorption spectroscopy, XAS, on a sample (107). The apparatus (100) and method involve a position-sensitive X-ray detector (105). In some aspects, counting the number of X-ray photons arriving at the X-ray detector (105) comprises correcting for charge sharing events in which an incident X-ray photon is detected at both the first detector segment (106) and the second detector segment (106). It also comprises only counting X-ray photons having energies within predetermined energy range. In some aspects, the X-ray detector (105) and the X-ray source (101) are scanned over an angular range during the XAS measurement.
