TIC traces obtained after TD-GC-MS analysis of Twisters® stirred in synthetic hydrothermal solutions. A: pH = 5.46, [Cl-] = 835 mM, [H2S] = 0.41 mM. B: pH = 3.13, [Cl-] = 305 mM. C: pH = 11.35, [Cl-] = 544 mM, [H2S] = 0.13 mM. D: pH = 11.86, [Cl-] = 5 mM, [H2S] = 3.3 mM. TICs were overlaid and are presented here with an offset for clarity.
