There is, indeed, a line just after the second Fe line, but I am almost sure this is not Zn, but possibly Co or Ni. The more, Zn is easily mistaken with Na (another line).

Hi Lukasz,


I am not entirely sure of the question, but I am fairly certain there is no Zn. I see an Fe Kalpha and Kbeta,, the next peak would be Co Kalpha (followed by Ni).


Cu Kaplha is around 8 KeV and Zn Kalpha is around 8.6 KeV. I would expect to see (on my system at least) the Zn K peak with an L peak that large, so I am fairly certain it is all Na.


Hope that helps


Regards

Frank

I agree no zinc there.
