“…This indicates that the total energy peak ratio of a detector Si (Li) to the exhaust peak is more than 2-3 orders of magnitude. Si (Li) detectors are used in a wide range of applications, including X-ray microanalysis, PIXE [4] and X-ray energy excitation.…”

The geochemical analysis of the middle Z precious metallic trace elements of the charnockite mineral composition was obtained by using proton induced X-ray emission at 3 MeV with a Si (Li) detector. Compared with other experimental nuclear analytical techniques like EPMA, XRF, and NAA, proton induced X-ray emission is used to detect with good accuracy and precision in the case of trace precious metals like Mo, Nb, Ru, Rh, and Ag, etc., in charnockite mineral composition due to the cross-sections with 3 MeV protons and good agreement. But peak resolution problems of K-X-rays of low Z and L-X-rays of the above elements which were presented in charnockite analysis must be solved and also change the detector parameters to obtain exact values in traces of the above elements in parts per million.
