✦ Synopsis
With the help of a fundamental parameter program, the matrix e †ect of multi-component complex samples and the composition of each elementÏs X-ray Ñuorescence intensity were calculated. A mathematical model for correcting the multi-component matrix e †ect was deduced theoretically. It provides two methods for calculating theoretical inÑuence coefficients a and b. The correction model and the inÑuence coefficient introduced in this paper have clear and deÐnite physical meanings. They gave satisfactory results when utilized in analyzing stainless-steel samples. The results also indicate that the e †ect of tertiary Ñuorescence cannot be neglected in some cases. From the results of comparison experiments, it is concluded that the tertiary Ñuorescence e †ect must be taken into consideration while analyzing Cr in a steel sample with a high concentration of Ni.
