Abstract
The present work was devoted to the investigation of highly polar capillary columns with stationary phases based on ionic liquids (IL) with cyanopropyl-containing cations. Five imidazole and quinolinium cyanopropyl-containing ILs have been studied. Their high polarity has been demonstrated. The measured Abraham selectivity has demonstrated an increase in specific types of interaction comparing to noncyanopropyl analogs. High thermal stability up to 300°C has been shown, especially for dicationic ILs. Examples of separation for one-dimensional and two-dimensional gas chromatography have been shown.
