Hybrid organo-silica columns

In principle, many organosilanes can be used as a second precursor to form the organo-silica monolith. Various coprecursors reported for the fabrication of hybrid organo-silica monolithic columns for EC or CEC are listed in Table 8.1. The structure of the organo-silica material is affected by the ratio of the tetralkoxysilane to the alkyltrialkoxysilane in the sol-gel reactions, the type of precursor used, and the processing parameters. This can be seen, for example, in the phase separation behavior of... [Pg.398]

Hybrid bonded-phase columns are being produced with carbon chains cross-linked chemically to the silica surface to reduce the amounts of free silanols and to increase the stability of the surface in the presence of high pH media.
