I think I'm working on too many projects this week!
Recently I was re-processing some quantitative X-ray maps for a client and noticed that the totals in the maps were exceeding 100% and was trying to figure out what went wrong:

Then (smack on forehead) I realized that I hadn't turned on the coating correction in the quant routines as seen here:

In the case of these samples, the standards were carbon coated, but the unknowns were not coated, so I also needed to turn off the specified coating on the unknown sample as seen here:

Now, after re-running the quantification on the maps, we obtain these (much better) quant maps:
