a m/z = 99 mass chromatograms of the free N-1 fraction of the cycle 37 halite phase and the shale layer between cycle 37th and 38th. N-alkane peaks are labeled with black circles. b m/z = 99 mass chromatograms of the desulfurized N-1. Peaks identified are labeled with numbers and listed in Table 2. c m/z = 191 mass chromatograms of the desulfurized N-1 fraction. d m/z = 217 mass chromatograms of the desulfurized N-1 fraction
