Abstract: In current study, poly(methacrylic acid-co-ethylene glycol dimethacrylate) (MAA-co-EDMA) monolith was successfully prepared for capillary hydrophilic liquid chromatography (cHILIC). The polymerization was optimized by changing the ratio of MAA to EDMA, the type and amount of porogen. The characterization indicated that "hydrophilic" monolithic column possessed homogeneous column bed, good permeability and narrow pore size distribution. Under HILIC mode, the "hydrophilic" monolith prepared with PEG and DMSO sho…
