Reversed-phase high-performance liquid chromatographic (RP HPLC) separation of small molecules on a nonporous octadecylsily (C18) spherical silica gel was compared with the separation or. conventional porous packings. Various alkylbenzenes were separated on three different types, nonporous, macroporous (...

The propylamido-modified C18 phase was prepared by bonding stearic acid to 3-aminopropyl-silica gel. The synthesis was simple and reproducible through amide formation by using N-hydroxysuccinimide and dicyclohexylcarbodiimide. This prepared stationary phase exhibited excellent abilities to separate polycyclic...

REVERSED-PHASE CHROMATOGRAPHYPROPYLAMIDOMODIFIED C18The synthesis and chromatographic properties of a propylamido-modified C18 stationary phase are described. The propylamido-modified C18 phase was prepared by bonding stearic acid to 3-aminopropyl-silica gel. The synthesis was simple and reproducible ...
The efficiency of accumulation of traces of dialkylphosphates, dialkylphosphorothioates and dialkylphosphorodithioates and at the same time of the parent organophosphorus pesticides, from aqueous solutions, was investigated by reversed-phase adsorption with octadecyl-modified silica gel (Sep-Pak C 18 ...
response at 280 nm.The effect of the different mobile-phase systems on the separations of these solutes is explained in terms of distribution of the solute molecules between the bulk mobile phase and the hydrophobic network of C 18 chains, bound to the surface of the silica gel base material...
The adsorbed amount of solvents was calculated per silica gel surface and per modeled surface of bonded phase which seem to give more correct data. Columns used in this study were nonend-capped with different coverage density of bonded C18 ligands. It allows investigating the influence of the ...
