In this study, we have synthesized perfluorinated, PGC using hepatadecafluoro-1-iodooctane, under different temperature conditions. In order to change the selectivities of PGC, it is necessary to develop a bonded PGC stationary phase. Attractive interaction between fluorinated stationary phase and fluorinated analytes results in strong retention compared to non- fluorinated analytes. Perfluorinated hydrocarbons however lack polarizabilty and display strong lipo- and hydrophobicity, hence common lipophilic and hydrophilic analytes have low partition coefficiency in fluorinated stationary phases. The polar retention effect on graphite (PREG) allows efficient separation of polar and non-polar solutes. Porous graphitic carbon (PGC) has unique properties desirable for liquid chromatography applications when used as a stationary phase. ![]() Olive, Daniel Cheng, Lidens Segre, Carlo U. ![]() Photoemission studies of fluorine functionalized porous graphitic carbon ![]()
