Zusammenfassung: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. 정도관리용 생체기준물질 중의 극미량원소에 대한 분석법을 확립하였다. 생체시료를 질산-과산화수소 혼합산화제와 함께 테플론 가압분해용기에 넣어 마이크로파 오븐에서 분해하는 시료전처리법(microwave digestion)을 사용하였다. 시료를 분해시키기 전에 정량할 극미량금속의 안정 동위원소를 첨가하여 동위원소희석 질량분석법을 적용하였다. 혈액과 소나무잎 기준물질에 이러한 분석방법을 적용하여 기준값과 일치되는 결과를 얻었다.
