Effect of Pb on Cu Isotope Ratio Measurement Using Multicollector-Inductively Coupled Plasma Mass Spectrometry
-
摘要: The employment of either doping or standard-sample-bracketing method for mass fractionation during isotope ratio measurement using multicollector-inductively coupled plasma mass spectrometry (MC-ICPMS) assumes that the instrumental fractionation is the same for both standards and samples. The effect of Pb in Cu solutions on Cu isotope measurement using MC-ICPMS is reported.
