title: [Application of factor analysis to identification of overlapped spectrum in XRF].
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 training set selection, the method can correctly identify spectrum overlaps. Studies reveal that identification ability can be affected by the number of data points and the concentrations of the overlapping elements.
