Abstract:
A process for making a chromatographic packing having a polymeric stationary phase in which molecules having the formula WHEREIN R3'' is a hydroxyl, or an aliphatic or aromatic hydrocarbon monovalent radical, and R4 is a monovalent aliphatic or aromatic hydrocarbon radical, ARE PARTIALLY PREPOLYMERIZED, CHEMICALLY BONDED TO A POLYVALENT METAL-CONTAINING SUBSTRATE, THE METAL HAVING A VALENCE OF 3-5, AND FURTHER POLYMERIZED. The polymeric stationary phase has a repeating unit of the formula WHEREIN A is -O- or a monovalent aliphatic or aromatic hydrocarbon radical, AND IS CHEMICALLY BONDED TO THE SURFACE OF THE SUBSTRATE BY AN WHERE SILICON IS PART OF A REPEATING UNIT.

Abstract:
A process for making a chromatographic packing having a polymeric stationary phase in which molecules having the formula
WHEREIN R3'' is a hydroxyl, or an aliphatic or aromatic hydrocarbon monovalent radical, and R4 is a monovalent aliphatic or aromatic hydrocarbon radical, are partially prepolymerized, chemically bonded to a polyvalent metal-containing substrate, the metal having a valence of 3-5, and futher polymerized. The polymeric stationary phase has a repeating unit of the formula
WHEREIN A is -O- or a monovalent aliphatic or aromatic hydrocarbon radical, and is chemically bonded to the surface of the substrate by an
LINKAGE, WHERE SILICON IS PART OF A REPEATING UNIT.
Abstract:
This invention relates to an improved packing material for chromatographic columns, prepared from a powder of uniform-sized porous microspheres composed of a plurality of interconnected colloidal oxide particles.
