This work presents a new triptycene-based dicationic guanidinium ionic liquid (TPG) as the stationary phase for gas chromatog. (GC). To knowledge, this is the 1st example of employing a dicationic guanidinium ionic liquid (GIL) for chromatog. analyses. As a result, the TPG column exhibited moderate polarity and column efficiency of 3840 plates/m and 3120 plates/m measured by naphthalene and 1-octanol at 120°, resp. Particularly, the TPG column exhibited distinctly advantageous performance for the challenging Grob test mixture and the isomer mixture of phenols and anilines over the monocationic GIL and its counterpart with dicationic immidazolium units (TP-2IL). Also, it showed higher selectivity towards the isomers of alkanes, alcs., diethylbenzenes, bromotoluenes, bromonitrobenzenes than the com. DB-35MS column. Also, the TPG column achieved improved thermal stability over the GIL column and excellent repeatability with the relative standard deviation values of 0.01-0.05% for run-to-run, 0.11-0.24% for day-to-day and 2.4-4.1% for column-to-column. Its application to GC-MS anal. of the essential oil of Mentha haplocalyx proved its good potential for anal. of complex samples.
