X ray apparatus includes a sample stage () for supporting a sample (), an X-ray source () and an energy dispersive X-ray detector (). A conical X-ray collimator () is provided either between the sample and the X-ray source or between the sample and the energy-dispersive X-ray detector, the conical X-ray collimator including a plurality of truncated cones arranged concentrically around a central axis, the truncated cones having a common apex defining a central measurement spot on the sample.

Conical collimator for X-ray measurements

Apparatus includes an X-ray source, a wavelength dispersive X-ray detector for measuring X-ray fluorescence (XRF) and an energy dispersive X-ray detectoragain for measuring X-ray fluorescence. Selected elements are measured using the wavelength dispersive process to reduce the overall measurement time compared with using only one of the two detectors or compared to a simple approach of measuring low atomic number elements with the wavelength dispersive detector and high atomic number elements with the energy dispersive detector. The selection can take place dynamically, in particular on the basis of the results of the energy-dispersive detector.
