Extract

The fundamental parameter approach for quantitative x-ray fluorescence analysis is an application of the equations derived by Sherman and by Shiraiwa and Fujino. Both derivations assume plane and smooth specimen surfaces and defined entrance and take-off angles of x-rays. Our investigation is dedicated to a more general description of measured characteristic signals. Consequently we have to deal with equations that allow us to account for the parameters mentioned below.
