ABSTRACT
The exciting possibilities of producing unique task-speci c ILs (TSILs) exist by simple modi cation of the cation and anion structure [3,4]. The resulting IL can be used to carry out designated applications or to serve a functional purpose in a method or device. In the eld of gas chromatography (GC), new stationary phases that exhibit unique separation selectivity, high ef ciency, and high thermal stability are in high demand and are particularly sought after. ILs possess many properties that allow them to function as multipurpose stationary phases that exhibit an unique dual-nature retention selectivity.
