Influence of non-spectral matrix effects on the accuracy of Pb isotope ratio measurement by MC-ICP-MS: implications for the external normalization method of instrumental mass bias correction
Ca, Al, Fe and Mg are identified as the dominant inorganic matrix components in Pb purified by anion exchange chromatography from a wide compositional range of silicate samples. Doping experiments demonstrate that these elements cause non-spectral matrix effects that result in inaccuracy of mass bia...
