Abstract
After the development of PIXE in 19701 and its successful application in a variety of scientific areas, considerable effort has been directed towards the development of nuclear microprobes in order to have available an instrument capable of measuring trace element distributions with a spacial resolution of a few µm. These nuclear microprobes are now available for more than 10 years and besides very useful applications in biology, geology and materials science, the process of improving the facilities is still going on. More recently, on a few locations, synchrotron radiation has been focussed down to µm sized spots with the same aim, to measure trace element distributions, in this case using X-ray fluorescence. In this paper, the possibilities of these instruments will be described, examples will be given and a comparison between the instruments will be given.
