Reliability Evaluation for Mercury Stable Isotope Ratio Measurement by MC-ICP/MS Seoyeong Choi1, Jaeseon Park2, Myungjin Kim2, Minseob Kim2, Jeeyoung Kim2, and Jongwoo Choi3† 1Department of Environmental Engineering,Ewha Womans University, Seoul 03760, Korea2Environmental Measurement & Analysis Center, National Institute of Environmental Research, Incheon 22689, Korea3Department of Civil and Environmental Engineering, Konkuk University, Seoul 05029, Korea Received May 23, 2024 / Revised May 29, 2024 / Accepted May 30, 2024 This study assessed the reliability of Mercury (Hg) stable isotope ratio measurements using MC-ICP/MS hyphenated with three different systems: wet plasma, dry plasma, and a cold vapor generator (CVG). Precision measurements using wet plasma improved with concentration, showing a range of 0.4 - 10.0% at 100 μg/L, with corresponding accuracy from 0.0 – 0.4%. By contrast, dry plasma demonstrated precision between 0.02 - 2.2% at 10 μg/L for 202/198Hg, with accuracy ranging from 1.2 - 1.4%. The CVG system, however, displayed significantly enhanced accuracy, from 0.2% for 199/198Hg to 0.9% for 204/198Hg at 0.1 μg/L. The study also incorporated a mass bias correction using a thallium (NIST 997 standard) internal spike, emphasizing the importance of maintaining a total Hg beam above 0.5 V to ensure measurement precision and accuracy. The findings suggest that the CVG method is most suitable for environmental samples with trace Hg concentrations, while both dry and wet plasma systems can serve effectively at higher concentrations (≥ 100 μg/L), given their analytical convenience and performance.
