Abstract
A monolithic stationary phase was prepared for liquid chromatography by in situ copolymerization of pentaerythritol triacrylate (PETA) and triallyl isocyanurate (TAIC). The morphology of monolithic column and pressure drop across the column were characterized. The effect of the porogen on the pore structure was characterized by SEM. Under the comparison condition, the monolith was suceessfully prepared and its mechanical strength had been studied. Furthermore, the poly (PETA-co-TAIC) monolithic column was applied to the separation of aromatic compounds. These successful application demonstrated that the purposed monolith was promising for HPLC separation of small molecules.
