window display the possible element, channel, KeV and Data(CPS) as
shown in above. The Green peak on right side is peak for Silver
K-a(22.16KeV) but it is not identified automatically because the center of the
sliver K-a moved to the left (called peak shift) as 21.96KeV. Therefore the
right two peaks should be determined as K-a and K-b of the Silver by
operator because there are no other possible elements regarding its energy
of the X-Ray. Using the proportional counter, it will be looked like as follows;
Because of wide resolution of the proportional counter, Cu and Zinc are
overwrapped each other. Sometimes this is very confused to identify the
peak. So if there is a peak in certain ROI (Region of Interest) it is possible to
exist overwrapped peak by neighborhood elements. View periodic table
menu on tool bar provides useful function to identify the spectra. Click View
