Abstract

A laboratory procedure is described for the removal and purification of Sr and Pb using Sr-Resin , for the purpose of thermal ionization mass spectrometry. Column preparation and elution can be accomplished within six hours, increasing efficiency in terms of time and reagent use relative to other established methods. The procedure is particularly useful for isotopic studies of organic-rich samples, as the extracted Sr and Pb yield quality analyses by thermal ionization mass spectrometry, with no evidence of elemental or organic interferences.
