From: TiO2-catalyzed synthesis of sugars from formaldehyde in extraterrestrial impacts on the early Earth
Panel (A) chromatogram of the derivatized sample of paraformaldehyde + TiO2 mixture treated with 10 laser pulses. Peaks of manifold products of mutual reactions among derivatization agents are marked 1–5. Panel (B) chromatogram of selected sugars measured for comparison. For the corresponding mass spectra detected in the sample see panel (C). For details see the Supplementary Information.
