A development of sample preparation technique for trace multi-element analysis of biological tissue by proton-induced. X-ray fluorescence spectroscopy is described.
The samples, which were sections of liver tissue from rats and guinea pigs, were found to be representative of the liver with respect to element content.More than 20 elements were simultaneously determined in the liver samples, and the detection limits for the heavy elements, i. a. Cr, Ni, As, Se, Sr, Mo, Cd, and Pb, were 0.2-2 ppm in dry matter.
