Individual First Dimension (1D) High Resolution Polar Columns

Polar, highly polar, and extremely polar GC columns are made with very selective GC stationary phases. These include polyethylene glycol, ionic liquids, and polysiloxane polymers with cyanopropyl functional groups. They are commonly used to analyze polar compounds (contain Br, Cl, F, N, O, P, and/or S atoms in addition to C and H atoms) and/or polarizable compounds (such as alkenes, alkynes, and aromatic hydrocarbons) that contain some double and/or triple bonds between carbon atoms. Dispersive (van der Waals forces), π-π, dipole-dipole, and dipole-induced dipole interactions are all strong with these columns. Moderate amounts of hydrogen bonding and basic interactions are also possible. Elution order is determined by the overall effects of all possible interactions.

Column choices (from least polar to most polar) are:
  • SUPELCOWAX 10, polar, polyethylene glycol phase, temperature limits 35 °C to 280 °C (isothermal or programmed)
  • SP-2560, highly polar, cyanopropyl siloxane phase, temperature limits subambient to 250 °C (isothermal or programmed)
  • SLB-IL111, extremely polar, ionic liquid phase, temperature limits 50 °C to 270 °C (isothermal or programmed)
