Bremsstrahlung excited standardless EDXRF analysis

This paper demonstrates that samples can be directly exposed to an X-ray tube bremsstrahlung to obtain their elemental composition. For this purpose, the bremsstrahlung spectrum from an X-ray tube has been detected with a Si(Li) detector. A theoretical spectrum was generated which fitted well with the experimental one. Four samples of known composition were then irradiated in the tube bremsstrahlung. A computer program was developed to obtain the elemental composition of the samples. Results obtained by this method (without the necessity of using any standard sample) were found to be in good agreement with our earlier findings
