摘要：

A method is presented for the energy-dispersive X-ray fluorescence analysis of samples with irregular shape or heterogeneous thickness. Based on the intensity of the coherently and the incoherently scattered excitation radiation, the procedure permits the calculation of an “effective thickness” of samples with unknown composition. Within certain restrictions, the method avoids weighing of the sample and allows the analysis of thin non-uniform targets. These features have been checked by analyzing simulated highly heterogeneous samples and thin targets simply prepared by drying a slurry of standard reference material on a Mylar carrier. © 1979, American Chemical Society.
