Abstract

A variant of the analysis of biological tissue (standard liver specimen, NCSZC 85005 Beef liver), where its reference specimen is q standard specimen of the geological matrix (soil, IAEA Soil-7), is considered. Concentrations of elements: K, Ca, Mn, Fe, Cu, Zn, Br, Rb, and Sr in the standard liver specimen are determined with and without consideration of the absorption of fluorescence emission by different matrices. The introduction of an absorption correction makes it possible to effectively take into account the difference in the absorption properties of the matrices under investigation (liver and soil) and determine the concentrations of chemical elements, which insignificantly differ from certified data.
