This happens periodically, someone (usually material scientist) says "I only care about atomic percents" and if I am not present, they leave with what I consider unpublishable data (the analytical totals are not in the sweet zone of 98.5/99-101). We've talked about this a few times over the years, but nothing ever gets done about it. This is a touchy subject, I understand, but we need to try to bring up the level of understanding of our students and users, who may never read a electron microprobe book or take a class.
So here's my suggestion: in the window (and printout) where normalized atomic compositions are displayed, insert a column (I'd say at the far left, after the line number, so it is immediately obvious) labeled "analytical total" (with a hover box explaining what it means to the unaware).
What say you all?
