Two 10-μm interplanetary dust particles collected in the stratosphere, have been analyzed with X-ray fluorescence excited by white synchrotron radiation (SYXFA) at the HASYLAB (DESY) in Hamburg. The measured abundances of the minor and trace elements with 16 < Z < 76 are in good agreement with abundances determined by PIXE analysis [1] of the same particles.
The results demonstrate that SYXFA is indeed a powerful
non-destructive technique for multi-element analysis of
micron-sized samples. Moreover we find that the combined
application of two such techniques, SYXFA and PIXE, to the same valuable particle lends high credibility to the results.
