ANKA-FLUO - X-ray fluorescence beamline situated at bending magnet port of the ANKA storage ring

Scientific applications

  • Environmental samples (e.g. toxic element bearing phases)
  • Environmental micro particle(e.g. dust particles stemming from accidents, aerosols, meteor impact ejecta)
  • Material research (contaminations in pure materials or homogeneity of thin films)
  • Art and Archaeometry (precious samples, old prints and paintings)
  • Biology: Organs of insects and small animals


MethodsSynchrotron X-Ray Fluorescence Microprobe (SR-µXRF):

  • X-ray Multielemental analysis technique on microscopically small area on sample surface or small volume element in the bulk.
  • Trace element detection at sub-ppm level (i.e. ~10ng/g for Sr in organic matrix)
  • Two dimensional mapping of the sample with µm resolution
  • Three dimensional information with confocal detector geometry or X-ray fluorescence computer tomography
  • Completely non-destructive


Total reflection x-ray fluorescence

  • surface-sensitive (grazing incindence)
  • analyzes trace impurities on the surface of flat samples (e.g. silicon wafers)
  • analyzes very small sample masses employed on a polished substrate.
  • probing depth variable from the sub nm to the µm range.
  • Minimum detection limit 108 atoms/cm2


Confocal X-Ray Fluorescence Microprobe:

  • three dimensional elemental distribution on a micrometer scale
  • elemental maps at different depth levels below the surface with a depth resolution of about 10-20μm
