A Comparison of a representative of one of the three replicate total ion chromatograms obtained from reacting magnetite with HCO3− and H2 at 90 °C and 16 bar total pressure for 16 h alongside controls. (a) Organic molecules generated using magnetite with H2 and HCO3−. (b) Control sample using magnetite with H2 (c) Control sample using quartz with H2 and HCO3− (d) Control sample using quartz with H2. B Magnification of the chromatogram region bounded by the broken line box in (A). Peaks with signal: noise ratio <5:1 or with a reverse match factor <65.0 to the NIST20 library are not labelled (Supplementary Data 3 for peak identities obtained from the NIST20 library).
