| Popis: |
Trace and ultra-trace levels of As, Au, Cd, Cs, Cu, Fe, Hg, Mo, Rb, Sb, Se and Zn can be determined simultaneously in human blood serum by radiochemical neutron activation analysis. Combustion of the irradiated serum in a Trace-O-Mat apparatus, followed by ion exchange, allows the detection of the γ-rays of interest. To calculate the concentrations, the K0 standardization method, adapted for the specific sample composition and sample-detector configuration, is applied. The accuracy and precision of the method were checked by the analysis of a second-generation reference material. The results agreed with the recommended values available for the most of the elements. |
