Correlation of methane with higher homologues. A: Methane (C1-GC) vs. higher hydrocarbon components (C2+−GC; ethane: black triangle; propane: green square), all determined by shorebased analyses with a gas chromatograph. B: Methane following shorebased analyses with a gas chromatograph (C1-GC) vs. methane following shorebased analyses with a quadruple mass spectrometer (C1-QMS).
