Key Points

This study aims to evaluate how the history of sample preparation affects the isotopic fractionation of lead.
Several batches of NIST SRM 981 dissolved in 0.15 mol/kg HNO3 were analyzed.
Isotope ratios 204Pb/208Pb, 206Pb/208Pb, and 207Pb/208Pb were determined using MC-ICP-MS.
K factors for isotope ratios were calculated from the measurements.
Different preparation histories resulted in varying isotope ratio measurements.
The k factors derived from the isotope ratios showed significant differences due to sample handling.
Isotopic fractionation impacts the accuracy of lead isotopic analysis based on sample history.
