An analytical method has been developed to determine trace elements in biological samples. The biological samples are added to a laboratory-bulit Teflon bomb together with nitric acid-hydrogen peroxide mixture and enriched stable isotopes. The samples are decomposed in a microwave oven. The decomposed sample solutions are analyzed by isotope dilution inductively coupled plasma mass spectrometry. The analytical results of the biological samples agree well with the reference values.
