Abstract

A correction method for X-ray fluorescence analysis of the heaviest element in a light element matrix was developed on the basis of the linear relationship between the Compton scattering intensity and the reciprocal of mass absorption coefficient. Using the equation obtained here, the heaviest element in the sample was determined over a large concentration range by measuring only the Compton scattering intensity of the primary X-rays and the fluorescent X-ray intensity for the analyte element. In this study, we employed copper in copper compounds as analyte element; the obtained copper concentrations agreed with the values calculated from chemical composition within 5% relative errors.
