Figure 1383 shows the sulfur and molybdenum peaks overlap in the EDS spectrum, but are separated and sharp in the WDS spectrum.

In a TEM (usually operated at voltages of 200 ~ 400 keV), the K lines (~17.45 keV) of Mo will be excited and visible, while in an SEM, it will be very different if operated at 20 keV or below (see overvoltage).
