| Abstract: | EFA method has been used in the processing of qualitative XRF data for metal alloys.With mathematically selected scanning steps and a mathematical model based on suitable trainning set selection,the method can correctlly identify spectrum overlaps.Studies reveal that identification ability can be affected by the number of data points and the concentrations of the overlapping elements. |
