Capillary columns based on different classes of single cation ionic liquids are prepared. Polarities of the columns are determined. The high thermal stability and maximum operation temperature of the prepared columns are demonstrated. Examples of separating test mixtures (complex high-boiling point mixtures of natural origin) are provided.
