Table 1 Identification of organic compounds and molecular sulfur in the hexane, DCM, methanol, and DCM/methanol extracts of serpentine blanks, Ryugu samples A0106, C0107, and the Orgueil (CI1) meteorite used for comparison

From: PAHs, hydrocarbons, and dimethylsulfides in Asteroid Ryugu samples A0106 and C0107 and the Orgueil (CI1) meteorite

  1. Shaded areas correspond to 2-dimensional chromatograms in Figs. 3 and 4 and Additional file 1: Figs. S1–S4.
  2. (−) none-detected; ( +) trace/low concentrations; (+ +) higher than trace concentration; (+ + +) highest concentration among samples. Roughly, (+ + +) accounts for the highest relative amount of compounds detected in the extract, (+ +) accounts for ~ 50% of highest amount, and ( +) for ~ 10% of highest. Columns showing the same sign, suggest that they contain roughly the same composition for each extract type and compound class.
  3. aThe m/z values were used to isolate the peaks within a range of 10 ppm.
