HPLC Guard Cartridge ZirChrom-SHAX G20, for 2.1 mm Columnn, Holder ZC-852-00 needed, 3 pc/PAK

ZirChrom-SAX quaternized polyethyleneimine-coated zirconia for strong hydrophilic anion-exchange. ZirChrom-SHAX has all the advantages of ZirChrom-SAX except that the surface is much more hydrophilic making it useful for anion-exchange of proteins.

• Stable from pH 1-12
• High anion-exchange capacity that can be controlled by the amount of polymer deposited on the porous zirconia substrate
• Different selectivity than silica or polymeric anion-exchangers
• Does not shrink or swell as a function of anionic strength or organic modifier content of the mobile phase.
• Thermally stable up to 80°C
