Interelement effects can be of great significance in the outcome of the analytical results from X-ray fluorescence technique. In an attempt to obtain rapid and accurate quantitative analysis a simple mathematical correction computer program is described with the aid of three different practical examples, namely steel 1, steel 2 and standard rock samples. The approach described in this study requires a minimum number of standards and can be run in any personal computer. The analytical values obtained by utilizing this program are within the accuracy level accepted by conventional techniques.
