Development of a standardless miniature XRF system for the analysis of actinides coupling MC modelling and fundamental parameters

Most of XRF devices all over the world use FP (fundamental parameters) algorithm that is a standardless approach. But for a singular device, such as the CBA XRF spectrometer focused on the analysis of actinide XL-lines by using a graphite monochromator, the use of FP algorithm is not possible as mentioned in, and a semi-empirical approach is still in use. This algorithm necessitates the preparation of many standards and a calibration process which is time consuming. A similar miniaturized XRF device has been developed. This system is a prototype dedicated to R&D experiments. The main goal of this new device is to be focused on standardless approach for quantitative XRF analysis.
