  • Combustion pretreatment-isotope dilution mass spectrometry
    Patent number: 9362096
    Abstract: Provided is a combustion pretreatment-isotope dilution mass spectrometry measuring concentration of a target element for detection contained in a target sample for detection by using an isotope dilution mass spectrometry, including: pretreating the target sample for detection by combustion during an isotope dilution mass spectrometry, to thereby stabilize an isotope and further improve analysis ability, and therefore, the present invention is expected to be utilized as an element analysis method surpassing accuracy of the existing mass spectrometry method.
