COMBUSTION PRETREATMENT-ISOTOPE DILUTION MASS SPECTROMETRY

摘要

The present invention relates to combustion pretreatment-isotope dilution mass spectrometry as a method for measuring the concentration of an element to be detected contained in a sample to be detected by using isotope dilution mass spectrometry, including a step of pretreating the sample to be detected by combusting the same during isotope dilution mass spectrometry. The present invention stabilizes an isotope and improves analysis ability, and thus is expected to be used as an element analysis method surpassing the accuracy of an existing mass analysis method.
