Effects of the Operation Parameters on Hydrophilic Interaction Liquid Chromatography Separation of Phenolic Acids on Zwitterionic Monolithic Capillary Columns
Original language description
Strongly polar phenolic acids are weakly retained and often poorly separated in reversed-phase (RP) liquid chromatography. We prepared zwitterionic polymethacrylate monolithic columns for micro-HPLC by in situ co-polymerization in fused-silica capillaries. The capillary monolithic columns prepared under optimized polymerization conditions show some similarities with the conventional particulate commercial ZIC-HILIC silica-based columns, however have higher retention and better separation selectivity under reversed-phase conditions, so that they can be employed for dual-mode HILIC-RP separations of phenolic acids on a single column. The capillary polymethacrylate monolithic sulfobetaine columns show excedent thermal stability and improved performance attemperatures 60-80 ?C. The effects of the operation conditions on separation were investigated.
