Sažetak
Proton induced X-ray emission (PIXE) spectroscopy was the first analytical method introctuced at the tandem Van de Graaf accelerator in Zagreb. The ability of PIXE to provide simultaneous multielemental analysis at the level of a few µg/g has been demonstrated to determine trace element concentrations in fish tissues (Zosterisessor Ophiocephalus Pall). Parallel analyses were carried out on aliquot samples using the XRF facility and the agreement of the results obtained by the two systems proved to be satisfactory. While the XRF cannot generally achieve the sensitivity obtained by PIXE, it can be used advantageously in determining certain trace elements. Thus, PIXE and XRF are shown to be complementary rather than competitive methods and together they offer an excellent analytical tool for nondestructive multielemental analysis of biological samples.
