A new imidazolium ionic polymer as a gas chromatography stationary phase for separation of high and wide temperature range complex samples

A new imidazolium ionic liquid polymer was synthesized and prepared as GC stationary phase for separation of coal tar samples. The coated capillary GC columns exhibited good thermal stability from room temperature to 380 °C, high separation efficiencies for coal tar samples, phthalates, PAHs and a maximum programmable temperature up to 400 °C.
