Process for preparing a stationary phase for a chromatographic column, the chromatographic column obtained and its use

摘要

the invention relates to a process for preparing a silica stationary phase, for the loading of a chromatographic column for separation of constituents in the liquid phase.;it is the first grafting functional groups such as amino, hydrolysis of the grafted stationary phase and total, and subsequent grafting of functional groups of the alkyl substituted type possible.;application to the separation of the constituents of a petroleum product.
