A monolithic ODS-silica gel column modified by saturating it with lithium dodecylsulfate (Li-DS) was used to demonstrate the high-speed separation of H + from other mono- and divalent cations, such as Na +, NH 4 +, K +, Mg 2+ and Ca 2+ using ion chromatography (IC). Using a 5...
Contributions of fluid-to-particle mass transfer and intraparticle diffusion to mass-transfer resistance in the octadecylsilyl-silica gel (ODS) column are almost equally great. Surface diffusion is dominant for the intraparticle diffusion in ODS. The logarithm of the surface diffusion coefficient ...

Silica rod columnA continuous porous silica rod column prepared by an alkoxy-derived sol-gel method in the presence of a water-soluble organic polymer was tested in the reversed-phase acetonitrile–water linear gradient elution of polypeptides with molecular masses of up to 80000. The silica rod ...
