GC×GC–HRMS analysis of fluoranthene and pyrene characterized by m/z 202.0778 ± 10 ppm, and methylfluoranthene and methylpyrene characterized by m/z 216.0918 ± 10 ppm from the baked serpentine blank, Ryugu samples A0106, C0107, and the Orgueil meteorite DCM extracts. 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 of fluoranthene and pyrene goes from 0.8 to 2.9 s (Start: 2%; Stop: 80%, Factor: 1.5), and for the isomers of methylfluoranthene and methylpyrene from 1.0 to 2.5 s (Start: 10%; Stop: 60%, Factor: 1). Isomers were not explicitly identified due to the use of a mixed isomer standard
