Dear Haytham, It should be relatively simple (and quick) to determine the metal in your sample employing either crystallized sample or solution using X-ray fluorescence (http://en.wikipedia.org/wiki/X-ray_fluorescence) at any beamline with a silicon drift detector (http://www.amptek.com/drift.html) set up for energy dispersive spectrometry (EDS).
We perform these analyses regularly at NE-CAT and I am sure there are a number of other beamlines set up for the experiment. Frank Murphy Beamline Scientist NE-CAT / Cornell University frankvmur...@gmail.com
