| Dissolved organic matter sulfur and carbon analysis of samples collected between 2010 and 2021 from various locations globally | SPE extracts were analyzed for their C and S concentrations and stable isotope compositions (δ13C and δ34S) via combustion elemental analyzer (EA) / isotope ratio mass spectrometry (IRMS). The system comprised a Thermo Scientific Flash EA IsoLink CN, coupled to a Delta V Plus IRMS via a ConFlo IV Universal Interface. The EA was configured with dual columns (combustion: WO3 over Cu; reduction: Cu metal) and a temperature-programmable GC column oven that allows both CO2 and SO2 to be eluted in the same run, as described by Phillips et al. (2021). Due to the high C:S molar ratios of DOM, CO2 was diluted by 88.4% following combustion via the ConFlo. Urea standards were run at the same settings to account for any possible fractionation of 13C by this dilution. | ConFlo IV Universal Interface |
