PROCESS FOR PREPARING A STATIONARY PHASE FOR A CHROMATOGRAPHIC COLUMN, THE CHROMATOGRAPHIC COLUMN OBTAINED AND ITS USE |
摘要 |
The invention relates to a method of preparing a stationary silica phase for the purpose of packing a chromatographic column intended for the liquid-phase separation of components. There are thus effected a first grafting with functional groups of the amine type, a complete hydrolysis of the stationary phase so grafted, and finally a further grafting with functional groups of the alkyl type, optionally substituted. A chromatographic column packed with the stationary silica phase can be used to separate the constituents of a petroleum product. |
