tailieunhanh - Study on the removal of interferences for the determination of 87Sr/86Sr isotopic ratio in petroleum drill-hole water samples using isotope dilution – inductively coupled plasma mass spectrometry (ID – ICP-MS)
In this study, the removal of matrix and isobaric interferences for the quantitative determination of 87 Sr/86 Sr isotopic ratio using ICP-MS was focused. The matrix effect caused by calcium at high concentration in petroleum drill-holes water samples was eliminated by using anion exchanger (BioRad AG1x8) in HNO3-methanol (95%) medium, meanwhile the isobaric effect due to rubidium presented in sample was removed by cation resin Bio-Rad AG50x8. |
