Three dimensional mapping shows elemental distribution across the surface and throughout the core of the sample. In this experiment, lithium carbonate tablets are used and surface distribution and depth profile of components have been obtained. Results show that concentration of calcium decreases and lithium increases by going from the surface toward the depth of the tablet. M3 ER -
