Is an EDX analysis of lithium nitrate possible? I have not been able to identify lithium nitrate. Are there any possible explanations for this? If possible, also cite literature sources.
Detection of Li is impossible for ordinary EDS system. While special detectors do exist now, and methods like quantification of Li by difference are advertized, they are not present in a usual SEM lab.
Thank you for the answer. What about nitrate? Is it still possible to detect nitrogen? Nitrogen was also not found in the spectrum.
There should be no problems with nitrogen. But you have to check with EDS operator if his system has a detector with Be window (some older systems may have it), then detection of N is also impossible.
I know I ask a lot, but why can't nitrogen be detected through the Be window? Is there a specific reason for this? This information is important for my bachelor's thesis. Can I mention in my thesis that I had a conversation with you? Would that be any problem for you? Thanks for the helpful answers.
Nitrogen, as other light elements, has low energy characteristic radiation. It is easily absorbed by Be, cannot come through it. And of course you can mention this conversation.
Thank you. In my spectrum I could identify carbon and oxygen. But carbon is lighter than nitrogen. What is the effect of carbon and oxygen that it was possible to identify it in EDX?
If you system can identify C and O, that means that your specimen has no identifiable quantities of N.
