Abstract: We describe the application of columns with highly polar stationary liquid phases based on pyridinium ionic liquids for the two-dimensional chromatography separation of bio-oil and product of coal pyrolysis. By using inverse combination columns—a first ionic liquid column and a second nonpolar column—good separation results have been obtained. In the analysis of coal pyrolysis products, the suggested approach provides a much better resolution between components in comparison with a less polar first-dimension column (based on polyethylene glycol). A good selectivity for the peaks of phenols is observed, and the group of phenols is well detached and separated from the group of diaromatics. A good separation picture was obtained also for bio-oil, the groups of phenols and guaiacol derivatives are distinguished with good resolution of substances within each group.
