ESI-Orbitrap sulphate isotopologue data for Dome C aerosol samples
Abstract
These ESI-Orbitrap MS sulphate isotopologue data quantify d34S-SO4, D33S-SO4, d18O-SO4 and D17O-SO4 in selected high-volume aerosol samples collected outside Concordia station (75°06'S, 123°20'E, 3233 m a.s.l.) from January - December 2011. The HSO4- isotopologue data were acquired and processed following the ESI-Orbitrap protocol for natural samples detailed by Saville et al. (in prep), using the Orbitrap Exploris 240 mass spectrometer (Thermo Fisher). The dataset, obtained in an experiment conducted in 2025, was acquired for comparison with traditional EA-IRMS (D17O) and MC-ICP-MS (d34S, D33S) isotope meausrements previously made on the same samples (Ishino et al., 2017; 2019; 2021), to test the performance of ESI-Orbitrap for SO4 isotopic analysis.
