The Preparation and Characterization of Organic-Inorganic Hybrid Material Amino Monolithic Column for Capillary Electro chromatography

摘要

In this paper a novel hybrid organic-inorganic amino hybrid material monolithic column for capillary electro chromatography (CEC) is preparation and characterization. The amido hybrid material monolithic column was prepared in situ cocondensation of tetraethoxysilane (TEOS) with 3aminoproplytriethoxysilane (3-APTES) via sol-gel procedure. The all kinds of factors that effect the morphology of monolith column were investigated. The results showed that the structure of monolithic column could be adjusted easily through altering the composition of sol solution.
