Application Note: A comparison of weighing methods prior to fusion
1 April 2020

Major investments are often made in state-of-the-art XRF equipment without knowing that the whole analytical chain, including the weighing step in sample preparation prior to fusion, is of crucial importance to get precise and accurate analytical results and consequently obtain estimated financial pay-offs. The weighing step in sample preparation by fusion for XRF analysis is all about knowing the exact weights of the sample and the flux (sample-to-flux ratio). Consequently, the weighing method, the tolerance accepted as well as the analytical method to obtain this ratio will affect the quality of analytical results given by the spectrometer.
