Abstract
A filler for liquid chromatography, said filler consisting essentially of a hydrophilic ion-exchanger obtained by copolymerizing a mixture of (A) 5 to 90% by weight of a polymerizable monomer containing one polymerizable double bond and at least one carboxyl group per molecule and having a hydrophobic parameter of not more than 2.3, (B) 10 to 95% by weight of a crosslinkable polymerizable monomer containing at least two polymerizable double bonds per molecule and having a hydrophobic parameter of not more than 2.3, and (C) 0 to 85% by weight of a monomer being different from the monomer (A), containing one polymerizable double bond per molecule and having a hydrophobic parameter of not more than 2.3; and a method for separating a biological material such as proteins, enzymes and amino acids by liquid chromatography using the aforesaid filler.
