The chromatographic columns play a crucial role in capillary liquid chromatography since the separation of analytes is based on the interaction between the analytes and stationary phases in columns.So far, the columns are classified as packed, open-tubular and monolithic columns.Open-tubular columns have relatively low sample loading capability.Monolithic column is a good alternative to packed column since its continuous stationary phase has higher permeability at a similar column efficiency and it does not need end frits.Up to date, the protocol for the preparation of silica-based monolithic columns usually included pretreatment of a capillary, sol-gel reaction, aging of gel, mesopores-tailoring of silica monolith, calcination, and modification of the silica monolith.Obviously, the aforementioned process for the preparation of silica monolithic columns is not only complicated, but also takes too much time.Therefore, it is necessary to develop a new method for the preparation of silica-based monolithic columns, which can reduce the preparation steps and shorten the time without compromising the separation efficiency.
