Hi guys,
I have noticed a fictituous oxygen peak thrown up on my EDS spectra on a SDD detector - I know it is fictituous as WDS says so. It is most likely the doubling peak.
The problem is, it is still quite aparent at 5% DT. I use the axiom that doubling peaks aren't an issue until you get up to 20-30% DT. If this is the case, is this an issue with the new SDD detectors - i.e. easy dounbling at low energies?
If you run the spectra through a stdless ZAF pkg, it comes up with 10% oxygen.
It is not very dependant on pulse processing setup.
I found the same on oxygen but other elements got in the way so I could not be sure.
Anyone have any experience on this?
