Preparation and Evaluation of Mixedalkyl-Bonded Silica for Reversed-Phase Liquid Chromatography
Abstract:
A mixedalkyl(C8~C13) bonded silica for reversed-phase liquid chromatography was prepared through the reaction of alkyl(C8~C13) triethoxysilanes with silica of average particle size 5 μm and surface area 210 m2/g. The carbon content of the mixedalkyl bonded silica was 5.21% by elemental analysis. The effects of the fixed phase on the chromatographic separation of polycyclic aromatic hydrocarbons and aromatic substituent isomers have been investigated.
