This thesis focuses on the development of new stationary phases for use in hydrophilic interaction liquid chromatography using TRIS‐based and phosphorylcholine typed monomers and porous silica particles as starting substrates. In this thesis, several ways of polymerizing highly hydrophilic mono‐ mers onto pore surfaces of silica supports are described, based on several “grafting from” schemes. ...

a microporous bisphenol a diglycidyl ether (dgeba) epoxified-polyethersulfone (pes) blend membrane (epes membrane) was prepared through dry-wet phase inversion. this study attempts to correlate the changes in membrane physical and chemical properties when the epes membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (vi)....

This review considers some of the difficulties encountered with the analysis of ionised bases using reversed-phase chromatography, such as detrimental interaction with column silanol groups, and overloading which both lead to poor peak shapes. Methods of overcoming these problems in reversed-phase (RP) separations, by judicious selection of the column and mobile phase conditions, are discussed....
