title: Characterization of internal surface reversed-phase silica supports for liquid chromatography.
abstract: Internal surface reversed-phase (ISRP) supports synthesized from commercially available porous silica particles with a variety of nominal pore diameters and specific surface areas are characterized with regard to physical and chromatographic properties. Bonded phase coverage, pore size, capacity and efficiency measurements are made upon the various ISRP supports in order to evaluate the effect that the physical properties of silica have upon the chromatographic performance of ISRP packings. In addition, various models that describe the pore structure of silica supports are discussed.
