A series of silica-supported polymeric ionic liquid (PIL)-based stationary phases derived
from a vinylic L-valine ionic liquid monomer and divinylbenzene (DVB) as the crosslinking agent
have been prepared and studied as gas chromatographic stationary phases. These coated gas
chromatographic columns exhibited good thermal stabilities (230–300 ◦C) and high efficiencies
(1700–2700 plates/m), and were characterized using a linear solvation parameter model in order to
understand the effects of the amount of DVB on the features of the resulting composite systems.
Their retention behavior and separation efficiencies were demonstrated using the Grob test. By tuning
the crosslinking degree for the IL-derived stationary phase, the separation selectivity and resolution
of different compounds were improved. The different retention behaviors observed for many analytes
indicate that these stationary phases may be applicable as new types of GC stationary phases. [-]
