Abstract

TONHI, Edivan; COLLINS, Kenneth E.; JARDIM, Isabel C. S. F.  and  COLLINS, Carol H.. Stationary phases for reversed phase high performance liquid chromatography (RP-HPLC) based on functionalized inorganic oxide surfaces. Quím. Nova [online]. 2002, vol.25, n.4, pp. 616-623. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422002000400017.

Particles of porous silica or other solvent resistent inorganic oxides can be functionalized by aliphatic (e.g., C-8 or C-18) or other groups to give stationary phases for use in reversed phase HPLC. The functionalization can be done by bonding of individual groups to the surface of the support particles, by producing an organic polymeric film from pre-polymers, or by adsorbing/immobilizing pre-formed polymers on the surfaces. These three types of functionalization are reviewed.

Keywords : HPLC; reversed phase; functionalized inorganic oxides.
