Say you are performing EDS mapping of a specimen composed of Al and Ga. When you generate your Al map, you notice that you have a rather high signal in regions when you should only have Ga present, dashed region in the image below. Furthermore, when you go back and perform a spectrum analysis on the dashed region, you do not see the presence of Al. In addition, the regions that do have aluminum only show a very small amount is present. The best explanation for this is _____:
