One of the big sources of background could be harmonics fluorescing Fe, especially for S. Aside from that, it only takes light filtering with something like mylar to knock down Si and Al in favor of S and Ca. You need a beamline which doesn't have a lot of Be in the way so that it can get decen

Dear all, I am interested in running some measurements of XANES and EXAFS K-edge spectra of elements such as Ca and S sorbed onto commonly found oxisol minerals, i.e natural kaolinite, gibbsite, hematite, and goethite. Besides appropiate filters to attenuate the fluorescence signals that come fro
