High-performance liquid chromatographic separation of carbohydrates on stationary phases prepared from polystyrene-based resin and tertiary amines

Synthesis and characterization of phosphorus‐containing polystyrene

“…For example, graft copolymers, dendritic copolymers, and high-branched star copolymers can be synthesized, with CMPSt as a macromolecular initiator of atom transfer radical polymerization (ATRP) [2][3][4][5] ; ion exchange resins, chelate resins, and adsorption resin with special functional groups can be prepared [6][7][8] ; catalysts and ligand supported on polymer used in organic synthesis can be produced, 9 functional microbeads of polymer can be produced by CMPSt post-crosslinking to be further used in the separation of biomacromolecules and in chromatography, as a stationary phase [10][11][12] ; polymer surfactants and compatibilizers for polymer blends can be synthesized, 13 and so on. Obviously, CMPSt will have wide applications in many scientific and technical fields.…”

HPLC Separation of All Aldopentoses and Aldohexoses on an Anion-Exchange Stationary Phase Prepared from Polystyrene-Based Copolymer and Diamine: The Effect of NaOH Eluent Concentration

“…The HPLC experiments were performed using a Shimadzu LC-10AD pump (Kyoto, Japan) with a CHRATEC VI-501PS electrochemical detector (Kyoto, Japan) consisting of an amperometric flow-through cell with a Ni-Ti alloy working electrode and a silver-silver chloride reference electrode [ 19 , 20 , 27 , 28 , 29 , 20 , 27 ]. The Ni-Ti alloy wires [Ni-Ti: NI205100 (55:45, w/w), 0.8 mm diameter] were purchased from Goodfellow (Cambridge, UK).…”

“…We have previously reported the preparation of the novel D n anion-exchange stationary phases with both a quaternary nitrogen atom and a tertiary nitrogen atom by the reaction of porous particles of the chloromethylated styrene-divinylbenzene copolymer with N , N , N ’, N ’-tetramethyl-α,ω-diaminoalkanes (diamines) [ 18 , 19 , 20 ]. The HPAE-ED analyses of monosaccharides, disaccharides, and oligosaccharides using the 100 mM NaOH eluent were successfully performed.…”

Development of Core-Shell Ion-Exchange Resin by Changing the Core-Shell Ratio and Its Elution Behavior with Carbohydrates

“…The resin used in this study consisted of a hard polymer core and a shell with functional groups in its porous layer. The porous layer shell was synthesized via the reaction of a chloromethylstyrene-divinylbenzene copolymer carrier with a tertiary amine [14,[18][19][20]. The thickness of the shell was adjusted by varying the weight ratio of the starting monomer for the core and shell (50:50, 40:60 and 30:70), while keeping the total mass of the monomers constant.…”
