Abstract:
1. A hydrophilic, monolithic chromatographic column including, as a stationary phase, a polyfunctional polyacrylamide gel, said polyacrylamide gel formed by polymerization of a monomer mixture, said mixture comprising acrylamide; bisacrylamide; a non-reactive filler compound for forming pores in the polyacrylamide gel; a polymerizable charge ligand of the formula RX wherein X is a functional group capable of maintaining a charge and R is an olefin functional group capable of free radical propagated polymerization; and a polymerizable cyano compound of the formula R′CN wherein CN is cyano and R′ is an olefin functional group capable of free radical propagated polymerization.
