Abstract

A simple porogen containing only DMF and aqueous buffer was used for synthesis of monolithic stationary media for CEC). Butyl methacrylate (BMA)-based capillary monoliths were obtained using proposed porogen together with acrylic/methacrylic cross-linking agents with different alkyl chain lengths. For this purpose, ethylene glycol dimethacrylate, butanediol dimethacrylate and hexanediol diacrylate (HDDA) were used. The monoliths with better electrochromatographic separation performance were obtained when the acrylic cross-linking agent with the longest alkyl chain length (i.e. HDDA) was used with the proposed porogen. The electrochromatographic separation of alkylbenzenes, phenols and benzoic acids were sucessfully performed in CEC particularly using poly(BMA-co-HDDA) monolithic stationary phase with the column efficiency up to 270?000 plates/m.
