“…Research into these polar and polarizable phases was started by Lee et al in the early eighties of the previous century and has resulted in a wide range of GC stationary phases with a broad range of selectivities [20]. Particularly in hyphenated systems, the low bleeding characteristics of the phenyl-or diphenyl-substituted phases and their properties are attractive [21]. Numerous combinations of phenyl and other polar groups have been evaluated for use as selective phases in GC, in which the fluorophenyl (methyl) substituted phases [22] and the cyanopropyl phases [23] are highlighted.…”

“…The McReynolds constants of ECP-9 and ECP-18 were quantitatively measured to investigate the polarity of these stationary phases (Table 3). We also listed the result of our previous study, which compared DPPP-25 (21.92% diphenyl-phenyl group in diphenyl-phenyl polysiloxane) [28] and commercial stationary-phase DB-17 (50% phenyl-50% methyl polysiloxane) [28]. Five probe molecules were benzene (X′), 1-butanol (Y′), 2-pentanone (Z′), 1-nitropropane (U′), and pyridine (S′).…”

In this work, we synthesized ethyl carbazole-grafted polysiloxanes, namely, ECP-9 and ECP-18, which possessed ethyl carbazole contents of 9% and 18%, respectively. The results of thermogravimetric analysis showed that ECP-9 and ECP-18 polymers lost 2% of weight at 365 °C and 380 °C. The minimum allowable operating temperature for the ECP-9 and ECP-18 was 40 °C. In addition, the ECP-9 and ECP-18 columns were thermally stable at 340 °C and 360 °C. The column average efficiencies of ECP-9 were 2306-3090 plates m −1 for a 10 m column and 2594-3438 plates m −1 for a 30 m column. The column efficiencies of ECP-18 were 2497-3428 plates m −1 for a 10 m column and 2829-3700 plates m −1 for a 30 m column. ECP-9 and ECP-18 as stationary phases exhibited moderate polarity based on the McReynolds constants. Given its specific dipole-dipole, dipole-induced dipole, π-π stacking interactions, and hydrogen bond force with solutes, the ECP stationary phases achieved excellent separation for aromatic isomers, substituted benzenes, polycyclic aromatic mixtures, polycyclic aromatic hydrocarbons, and fatty acid esters with satisfactory peak shapes.

“…So, an effective method for the rapid gas chromatographic separation still needs to be developed. Stationary phases, such as diphenyl-phenyl polysiloxane, 31 b-cyclodextrin, 32 UIO-66, 33 gold nanoparticles, 34 imidazolium ionic polymer 35 and carbon nanotubes, 5,8,36 have been successfully applied in GC separation, but high temperature, 9,[35][36][37] long analysis time 31,38 or temperature-programming 6,8,33,39 is oen needed.…”
