According to fundamental parameter method theory

gained the key parameters such as mass-absorption coefficients and excitation factors and wrote the calculation procedure.In experiment

a series of lead brass alloy standard samples were analyzed with an energy dispersive X-ray fluorescence spectrometer and calculated the contents of Cu、Zn of the samples via the fundamental parameter calculation procedure.The result shows the fundamental parameter method can overcome the absorption-enhancement effect between Cu and Zn elements well.The measured contents of Cu and Zn is respectively 54%–64% and 33%–45%

the precision of the method is 0.10% and 0.15 % respectively for Cu and Zn.
