2. Multi-element analysis
2.1 Choice of analysis conditions
The nature and energy of the particles delivered by the gas pedal will be chosen according to the elements to be analyzed (see article . The ions most often used for PIXE analysis are H + protons, whose ionization cross-section in the few MeV range is, for most elements, greater than that of heavier particles. Ion energies can be selected to analyze as many elements as possible. The K lines of light atoms (11 < Z < 20) can be excited using protons with energies between 1 and 2 MeV, whereas heavier elements (20 < Z < 92) require particles with energies above 2 MeV. The variation in beam energy can also be used to probe different thicknesses of material to obtain a concentration...

Processing software
There are around ten PIXE spectrum processing software packages, most of them developed by research laboratories. They are either based on deconvolution with calculation of peak areas, or on fitting a simulated spectrum to the experimental spectrum. They all enable concentrations to be calculated.
