Abstract

An emission-transmission method in X-ray fluorescence analysis, based on theoretical considerations, has been applied for eliminating matrix effects due to variations in the chemical composition of samples. The measurements have been carried out in so-called compact geometry, using153Gd source of the primary radiation and a NaI(Tl) crystal (3″ in diameter, 2 mm thick). The element to be determined was antimony in a CaCO3 matrix with various admixtures of CuO. A method of semitheoretical construction of nomograms has been introduced for the evaluation of the measurements. Six variants of the method are discussed, and a criterion permitting to find the most useful variant is given. The theoretical considerations have been confirmed by the experiments.
