Abstract

Lead isotopic ratio determination is significantly affected by the isobaric interference of mercury (²⁰⁴Hg), thus many studies lack ²⁰⁴Pb/²⁰⁶Pb values. Removal of ²⁰⁴Hg from sample is resource consuming, while mathematical correction can be employed if the Hg isotope ratio in the sample is known. Triple quadrupole inductively coupled plasma mass spectrometry (TQ-ICP-MS) offers a mechanism for removing the ²⁰⁴Hg, by pressurizing the reaction cell with ammonia, that reacts with ²⁰⁴Hg positively charged ions rendering them neutral, thus filtering them out and removing them from the ion beam. The Pb isotope ratio determination can be used as “fingerprint” to identify the sources of contamination and environmental pollution. The method developed based on this mechanism was used for Pb isotopic ratio determination in cave sediment samples. Relative standard deviation of this method was between 0.36% - 0.59%.
