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 from elements such as Al and Si, what would the other instrumental conditions (e.g detector type, photon flux, etc...) needed for getting usable spectra of those elements in diluted samples? Any suggestion on the more adequate beamline to carry out such measurements?

Kind regards,
