This experiment brief demonstrates how the CPS mapping feature in APEX 2.0 is helpful for understanding the variations in X-ray count rate across the rough surface of a vitamin caplet cross-section. By applying the CPS normalization, a clearer view of the true elemental signals is provided to better interpret the spatial distribution of components and phase segregations in the vitamin caplet.
