Abstract

A new hybrid monolithic column (HMC) was prepared in stainless steel chromatographic column using nitric acid as catalysis and methyltrimethoxysilane as sole precursor. The influences of the precursor ratio, catalyst concentrations, gelation temperatures on properties of HMC were investigated, and the formation mechanism of the HMC was discussed. The obtained monolithic column was characterized by (SEM) and chromatographic evaluation. The results showed that the homogeneous network skeleton structure was formed in the HMC with a controlled microchannel (10.3 m) and nanopore (13.6 nm) and the lower shrinking ratio of HMC in comparison with silica monolithic column were obtained.
