X-ray Fluorescence (XRF) Analysis


X-ray Fluorescence (XRF) is a well-established bulk analytical method for qualitative as well as quantitative determination of several elements in a sample, independent of their chemical form. Depending on the detection system configuration, can be classified as Energy Dispersive (EDXRF) or Wavelength Dispersive (WDXRF) systems.

 

Setup: X-ray Fluorescence Microscopy (XRFM)


This setup allows performing experiments with an X-ray microbeam. The microfocusing optics consists of a pair of bendable mirrors arranged in the so called Kirkpatrick-Baez configuration (KB). The X-ray microbeam is around 12 microns (vertical) by 22 microns (horizontal) in size. Fully remote-controlled XYZz sample stages can operate in air or under a nitrogen gas environment. The -XRF setup also includes an optical microscope and a Silicon Drift Detector (SSD).
