description: Additional file 1: Figure S1. GC×GC–HRMS analysis of alkanes/alkenes characterized by a combination of characteristic fragments at m/z 57.0699±10ppm and 71.0856±10ppm from the baked serpentine blank, Ryugu samples A0106, C0107, and the Orgueil meteorite DCM extracts are indicated with white rectangles. The indicated species were identified via accurate mass and a mixed isomer standard. Signal outside the white circles are unidentified species. The insert color scales represent relative peak intensities, where colder colors (blue toward green) indicate lower values and warmer colors (yellow to red) higher values. The timeframe for the second dimension (Time2) in each chromatogram goes from 0.84 to 1.1 s (Start: 5%, Stop: 100%, Factor: 1). Figure S2. GC×GC–HRMS analysis of alkylbenzenes characterized by a combination of characteristic fragments at m/z 91.0541±10ppm and 105.0698±10ppm from the baked serpentine blank, Ryugu samples A0106, C0107, and the Orgueil meteorite hexane extracts are indicated with white rectangles. The indicated species were identified via accurate mass and a mixed isomer standard. Signal outside the white rectangles are unidentified species and column bleed. The insert color scales represent relative peak intensities, where colder colors (blue toward green) indicate lower values and warmer colors (yellow to red) higher values. The timeframe for the second dimension (Time2) in each chromatogram goes from 0.7 to 3.7 s (Start: 1%; Stop: 100%, Factor: 1.5). Figure S3. GC×GC–HRMS analysis of molecular sulfur(S8), dimethyl disulfide, dimethyl trisulfide, dimethyl tetrasulfide characterized by a characteristic fragment at m/z 63.9437±10ppm from the baked serpentine blank, Ryugu samples A0106, C0107, and the Orgueil meteorite MeOH extracts. Orgueil is dominated elemental sulfur which has the same fragment, though S8 is present in all samples (Figure S4) the fragment monitored here is below the detection limit in all but Orgueil. The insert color scales represent relative peak intensities, where colder colors (blue toward green) indicate lower values and warmer colors (yellow to red) higher values. The timeframe for the second dimension (Time2) in each chromatogram goes from 2.2 to 4.2 s (Start: 30%; Stop: 70%, Factor: 1). Figure S4. GC×GC–HRMS analysis of molecular sulfur (S8) as seen in the total ion chromatogram (TIC) from the baked serpentine blank, Ryugu samples A0106, C0107, and the Orgueil meteorite MeOH extracts. The sulfur abundance in Orgueil is so large that the chromatography is overloaded and thus the peak is very broad. The insert color scales represent relative peak intensities, where colder colors (blue toward green) indicate lower values and warmer colors (yellow to red) higher values. The timeframe for the second dimension (Time2) in each chromatogram goes from 0.5 to 3.0 s (Start: 50%; Stop: 65%, Factor: 1). Figure S5. GC×GC–HRMS analysis of PAHs standards. The insert color scales represent relative peak intensities, where colder colors (blue toward green) indicate lower values and warmer colors (yellow to red) higher values. The timeframe for the second dimension (Time2) in each chromatogram goes from 1.5 to 3.0 s (Start: 3%; Stop: 100%, Factor: 1.5).
