I intend to modify numerical methods of spectrum treatment. I want to improve the way PIXE spectra are treated to take the real physical interaction into consideration. For example, the analysis of PIXE spectrum will integrate escape peaks and sum peaks and the removal of background induced by secondary electron bremsstrahlung will be completely modify. To do this, a new computer program that will allow to obtain not only the peak intensity but also their conversion to elementary concentration will be written. Moreover, this program will be associated to the data acquisition programs, which will allow direct and on-line analysis.
Sample preparation is also very important for the analysis quality.
In this optic, an electrophoresis system that will be specially intended to protein and macromolecule analysis by PIXE will be built. This contribution principally concerns the technique setting and the assessment of tests that will guarantee analysis quality.
