A new fundamental parameter method applied to energy dispersive X‐ray spectrometry is presented. Am‐241 and I‐125 radioisotope sources were used for excitation. The method is applied to copper–zinc–lead ternary and copper–zinc–lead–tin quaternary alloys and to high‐alloy steel specimens. It is also tested using data given in the literature. The measurements and calculations were performed on‐line by a program running in a 16K, 12 bit minicomputer interfaced to a multichannel analyser. The results were compared with wet chemical analysis.
