Hello, all!
I have been successfully measuring F in apatite up until today, when I 'improved' several of my standard bundles by finally going off and collecting high-count peak shape references. Now, even when I assign a F standard and x-ray line in the Quant Alien, the element just vanishes from the final results. I don't know how adding non-auto shape references would do this, but it is the only thing I can think of that changed. Many of the other standard bundles I 'improved' at the same time still give good results.
What would cause DTSAII to exclude a specified element in the results?
