This is the wrong list for EDX.  Try the electron microscopy LIST-PROC.

Subject: EDX system

I want to understand how does the EDX system actually work.

I use horiba supplied EDX system with an atmospheric window equipped with lithium drifted sillicon dtetctor. I understand the generation of x rays and detection of these x rays by detector in the liquid nitrogen cooled EDX detector. I use a software supplied with the instrument called EMAX

From this point the point of generation of this signal how does the data gets analysed and displayed, There are terms like fit index and some times though the spectra shows some peaks but the relative weight percentages are in negative values.............!!!

I will be happy if people who have a detailed understanding of this phenomena comment on the entire process of translation of the electronic signal to the data  display by the software happens if there is any detailed document available i would like to go through it
