In 2005, Prof. Daniel W. Armstrong (University of Texas at Arlington) showed that dicationic and polycationic ionic liquids could successfully be used as viable GC stationary phases. These consist of two or more organic cations joined by a linkage, and associated with anions, which can be either inorganic or organic. Ionic liquid phases differ physically and chemically from non-ionic liquid stationary phases.
They are much smaller compared to big, bulky polysiloxane polymer and polyethylene glycol phases, plus there are no active hydroxyl groups. These features lead to greater stability, even in the presence of moisture and/or oxygen.
Many modifications are possible to alter selectivity. The base structure can be dicationic or polycationic. There are numerous cation, linkage, and anion choices. Pendant groups can be added to cations and/or linkages.
Ionic liquids have the opportunity to impact current practices along several paths:
Columns can be engineered with identical selectivity to non-ionic liquid columns, but with higher operating temperatures and less susceptibility to damage from moisture and/or oxygen.
Columns can be engineered with completely unique selectivity to non-ionic liquid columns, producing good peak shape and resolution for compounds of varying functionality.
Columns can be used in multidimensional separations, due to their engineered orthogonality and high thermal stability.
