Abstract:
A new software package "BIOPIXE" with emphasis on biological samples inhomogeneous in mass is presented. PIXE and STIM measurements were carried out on pixel-by-pixel basis. The elemental concentrations are evaluated using GUPIX. Main features of BIOPIXE are correction of thermal shifts during long time measurements (72 h), offline evaluation of elemental concentrations of arbitrary regions and, especially, true elemental maps of samples inhomogeneous in mass.
