a
Analyte
Analyte concentrations normalized to 100% (Mol. % is approximately equal to Vol. % )
b
Addition of helium negates the ability to detect native helium and may negate the ability to detect hydrogen.
HC= Hydrocarbons
nd = not detected
na = not analyzed
Stable isotope results based on multi‐point laboratory calibration
Error 13C < 0.5 ‰
Error D < 5.0 ‰
