What is On-line Pyrolysis of Hydrocarbons Coupled to High-precision Carbon Isotope Ratio Analysis about?
High-precision carbon isotope ratios are reported for gas phase pyrolysis products of toluene and n-alkanes from C5 to C10. Toluene yields benzene and methane exclusively, while n-alkanes yield methane and ␣-olefins. Pyrolysis product isotope ratios were determined with a mean precision of SD(δ 13 C) < 0.2‰ and were not strongly dependent on pyrolysis temperature. Carbon yields from benzene and methane appear at the expected ratio of 6:1 at 4% fragmentation but drop at fragmentation 15‰ on average compared to the parent alkanes for all but octane, where it was enriched by almost 1‰. Complementary binary fragment isotope ratios were closely correlated to the isotope ratio of the parent. These data show that high-precision isotope ratios of hydrocarbon pyrolysis products are indicative of source and will be useful for fingerprinting and on-line position-specific isotope analysis (PSIA).
