HPLC Columns

TSKgel SuperQ-5PW

TSKgel SuperQ-5PW columns are packed with porous hydrophilic polymer beads which are modified with a strong anion exchange group. The resulting product exhibits very high protein capacities. TSKgel SuperQ-5PW columns are used for the separation and analysis of proteins, oligonucleotides and other biologically active molecules.
