Hi there,
do you know if there is any software able to transform a mineral (or amorphous phase) analysis (e.g., a microprobe result) into an EDS spectrum? Of course there are software able to do the inverse (i.e., from EDS spectrum to qualitative/semiquantitative analysis), but I did not find a program able to do the contrary.
Thanks
The NIST has developed a program, DTSA-II for analysis of EDS spectra. It has the capability to simulate EDS patterns from samples of known chemical composition, so it might be what you're looking for.

Great Philip!
Yes indeed, this is what I was looking for. Now I download the software and will let you know.
Thanks in advance,

Apart from the DTSA-II software from NIST I would guess that most commercial EDS analysis software packages also have te ability to generate/simulate a spectrum based upon elemental composition. In our lab we use Oxford and Edax software for our analyses and both have this feature.
With DTSA-II you have more control on the parameters (can also simulate effects of surface roughness and low vacuum), but if you would want to do a direct comparison with an experimental spectrum the simulation within in the original analysis package might be more usefull. In this way you keep the same "errors" that are present in that specific algoritmic implementation.
Yes indeed Peter.
The DTSA software is not of easy use because of too many parameters to work on. I would have preferred to have a simple software in which it was possible to transform with few steps EMP results into EDS spectra. Unfortunately the SEM I use (we have also a Cameca SX50 in my department) does not have the Oxford-Edax softawre you talk about.
if you just want to get a general idea of what the spectrum should look like it is not that hard to get simulated spectrum in high vacuum mode. Have a look at the DTSA website http://www.cstl.nist.gov/div837/837.02/epq/dtsa2/ specifically at the simulation tab. This provides a step-by-step manual. Or at a pdf guide like this one: http://epmalab.uoregon.edu/Workshop3/NIST%20DTSA-II_guide.pdf
However if you want to get the best possible results, I'm afraid that you need to have to get yourself acquinted with all the details which indeed takes some effort.
