The x-ray microbeam scanning facility in our laboratory at Chalmers Un
iversity of Technology/Goteborg University is described in terms of op
tical and mechanical design, imaging capacity, spatial resolution, and
sensitivity. Different types of visualization of the elemental distri
bution are demonstrated and application of image processing is discuss
ed. Examples of applications in the field of single-particle analysis
as well as tree ring analysis are given. Future perspectives of the te
chnique are also discussed.
