中文摘要 | a c18-silica hybrid monolithic column was prepared via the “one-pot” process. in which, the alkoxysilanes precursors of tetramethoxysilane (tmos) and vinyltrimethoxysilane (vtms) was firstly hydrolyzed in a 0.01 m acetic acid solution, and then the organic monomer of n-(2-(methacryloyloxy)-ethyl)-dimethyl- octadecylammonium bromide (mdoab) for introducing the c18 moiety to the monolith along with the initiator of aibn were added into the hydrolyzed solution. after sonicated for 15 min, the mixture was introduced into a pretreated capillary. the polycondensation of alkoxysilanes and the copolymerization of organic monomers and as-precondensed siloxanes were subsequently carried out at proper reaction conditions. the morphologies of the synthesized organic-silica hybrid monolithic columns were characterized by scanning electron microscopy (sem). the performances of the resultant c18-silica monolithic columns were investigated by capillary electrochromatography (cec) and the results confirmed that the mdoab was successfully incorporated into the silica monolithic matrix. furthermore, the c18-silica hybrid capillary monolithic column was applied in the analysis of bsa digest by μlc-ms/ms to demonstrate its potentials in proteome analysis. |
