For X-ray/Synchrotron: That depends from the difference of the atomic numbers Z between A and B. If A and B are neighbors in the periodic table, nearly impossible. If the difference is large, you may go down to percents. In the case of neighbors in the periodic table, there is the option of using neutron diffraction.
