Abstract:
1. An apparatus configured as a determining device, adapted to determine the thickness of a zinc layer on an iron layer of a test object and the iron content in the zinc layer on the iron layer of the test object, comprising: an x-ray source, emitting x-ray radiation to the test object having the zinc layer on the iron layer; a first fluorescence detection device determining a first fluorescence radiation due to iron in the test object scattered under a first angle segment from the test object; a Compton radiation detection device determining a Compton scattering based on iron in a test object scattered under a first angle segment from the test object, the Compton detection device including: a second fluorescence detection device determining a second fluorescence radiation due to iron in the test object scattered in a second angle segment from the test object; a third fluorescence detection device determining a third fluorescence radiation due to iron in the test object scattered in the second angle segment from the test object; a first analyzing device adapted to determine the thickness of the zinc layer on the iron layer of the test object based on the first fluorescence radiation and the Compton radiation; and a second analyzing device adapted to determine the iron content in the zinc layer based on the first fluorescence radiation, the second fluorescence radiation and the third fluorescence radiation.
