Abstract

The isobaric interference for boron isotopic measurement by negative thermal ionization mass spectrometry (NTIMS) has been studied,The result shows that the CNO^- is not only from the organic material,but also from nitrate in loading reagent in NTIMS,Monitoring the mass 43 ion intensity and 43/42 ratio of blank are also necessaary fro the boron isotopic measurement by NTIMS,other than is only boron content.
