Bayesian inference massively cuts time of X-ray fluorescence analysis!

Saved seconds add up to hours over multiple measurements

10-Jan-2023

How can the component elements of an unknown material, such as a meteorite, be determined? X-ray fluorescence analysis can be used to identify an abundance of elements, by irradiating samples with X-rays and analyzing the spectrum they emit and can detect many elements simultaneously. For this ...
