The irradiation of test pieces with x-radiation causes an energetic excitation resulting in the emission of element and concentration depending fluorescence radiation.
The quantitative chemical analysis gets possible by calibration with the aid of reference material. In contrast to wet chemical methods this procedure is marked by a significant time saving. Nonetheless it is to calculate with a lower sensibility in the range of traces.
Qualitative investigations are possible, too. In context with different technologies of preparation a diverse application for massive samples as well as powder or granules (raw materials) appears.
(Samples: glass pills, Æ 40 mm, thickness: 1-10 mm; powdery materials or granules)
