NOVEL NANOCOMPOSITES AND THEIR APPLICATION AS MONOLITH COLUMNS

摘要

PROBLEM TO BE SOLVED: To provide novel materials for chromatographic separations, processes for their preparation, and separation devices containing the chromatographic materials, in particular, hybrid inorganic/organic monolith materials comprising a polymerized scaffolding nanocomposite (PSN), in which the nanocomposite contains a scaffolding functionality capable of chemically interacting with a surface of a second material.SOLUTION: The hybrid inorganic/organic materials, prepared according to the outline shown in the figure 1, have enhanced wall adhesion and increased resistance to shrinkage as compared to prior art monolith materials. The improved adhesion of the monoliths enables the preparation of capillary columns with an internal diameter (I.D.)≥50 μm.
