The in situ analytical pyrolysis of two different organic components of a synthetic environmental matrix doped with [4,9-13C] pyrene

摘要: Abstract Laser micropyrolysis GC–MS was used for in situ analysis of the coal and lignin components a synthetic mixture. Designed to mimic environmental matrices such as soils sediments, mix comprised several possible soil precursors also amended with [4,9- 13 C]pyrene part concurrent research on interaction PAH pollutants sedimentary organic matter. The labeled spike consistently detected major pyrolysate analyses both mix, indicating its effective sorption by these moieties mix. remaining hydrocarbon distribution from dominated guiaicyl (i.e. methoxyphenol) compounds, whereas high abundances aromatic (e.g. benzene, naphthalene, phenol alkyl derivatives thereof) aliphatic n- alkene/alkane, prist-1-ene, hopanes) products were coal. Apart concentrations C-spike, data very similar molecular obtained respective pyroprobe pyrolysis pure samples. untainted apart C-spike) signatures constituents indicates minimal contamination other successfully demonstrating capability laser technique selectively analyse discrete entities within complex heterogeneous mixtures.
