Analysis of Organic Material Difficult to Recover From Oil Shale

A new approach for molecular characterisation of sediments with Fourier transform ion cyclotron resonance mass spectrometry: Extraction optimisation

“…MeOH, a polar solvent, has been successfully used in examining meteorites (Schmitt-Kopplin et al, 2009). Pyridine extraction has been employed to examine more mature sediment such as kerogen , coal (Wu et al, 2003) and shale (McKay and Sterling Blanche, 1985), suggesting it might also be successful for immature sediments.…”
