SAMPLE PREPARATION PROCEDURE FOR PIXE ELEMENTAL ANALYSIS ON SOFT-TISSUES

Trace element analysis is one of the most important field in analytica l chemistry. There are several instrumental techniques which are appli ed for determinations of microscopic elemental content. The PIXE (Prot on Induced X-ray Emission) technique is one of the nuclear techniques that is commonly applied for such purpose due to its multielemental an alysis possibilities. The aim of this study was to establish the optim al conditions for target preparation procedure. In this paper two diff erent approaches to the topic are presented and widely discussed.(1,2) The first approach was the traditional pellet technique and the secon d one was mineralization procedure. For the analysis soft tissue such as liver was used. Some results are also presented on water samples.
