ABSTRACT:
A packing material for liquid chromatography bears a polyalkylene polyamine moiety linked through a spacer moiety as the pendant group to a porous silica gel coated with a silicone polymer, and optionally is crosslinked by a crosslinking agent on two or more amino group of the different polyalkylene polyamine moieties, and a process for production thereof. Such a packing material is especially useful in the analysis of sugars.
