Separation of xylose and glucose on different silica-confined ionic liquid stationary phases

Application of ionic liquid for extraction and separation of bioactive compounds from plants

“…On the other hand, xylose is a raw material for the production of xylitol [191], which is a high value sweetener in the biomedical sector [192]. Therefore, xylose and glucose, as the main hydrolyzed products of the plant cell wall, were separated using IL-based silica as the stationary phase in HPLC [179]. Five different stationary phases were synthesized and characterized.…”

Preparation and evaluation of 2-methylimidazolium-functionalized silica as a mixed-mode stationary phase for hydrophilic interaction and anion-exchange chromatography

“…For the moment, there have been a number of studies about imidazolium ILs modified silica as stationary phases of packed columns by different methods in HPLC [22][23][24][25][26][27]. Our research group firstly prepared a 1-methylimidazolium (N-methylimidazolium) modified silica stationary phase (Sil-1-MIm) for the separation of organic and inorganic anions and some basic compounds, finding that the phase displayed a strong anion-exchange mechanism and coexistent reverse-phase interaction [28].…”

Versatile ligands for high-performance liquid chromatography: An overview of ionic liquid-functionalized stationary phases

“…Apart from Stalcup's meticulous works in depicting the retention characteristics of the SCIL SPs, study on the applications of SCIL SPs functionalized with short alkyl chains was conducted by Bi et al [81,82] and our group [56,57,59,60]. Given the improved RP performance of SCIL SP prepared via polymerization procedure, large aromatic probes, such as PAHs, were included in the chromatographic assessment [83].…”
