Abstract (en)

[origin: DE19618774A1] To determine also the concentration of foreign atoms whose X-ray fluorescent spectrum approximates or coincides with that of a base material (54) in samples (48) that have been given a coating (56), the invention proposes that in determining the concentration of the foreign atoms, fluorescent radiation (58) glancing off the surface of the sample be analyzed.
