Agilent Bio IEX Guard Columnss

Choosing to use guard columns can help reduce operating expenses, by reducing the frequency of analytical column replacement. The guard column prevents damage caused by particulate matter and strongly adsorbed material. To maintain an adequate capacity for sample impurities, choose a guard column with an internal diameter similar to the column internal diameter. Ideally, the packing of the guard column should be the same as the analytical column so that the chromatography of the analytical column is not altered.

Agilent Bio Ion-Exchange HPLC columns are packed with polymeric, nonporous, ion-exchange particles. Bio Ion-Exchange Columns are designed for high resolution, high recovery and highly efficient separations of peptides, oligonucleotides and proteins. The Bio IEX family offers strong cation-exchange (SCX), weak cation-exchange (WCX), strong anion-exchange (SAX) and weak anion-exchange (WAX) phases. All Bio Ion-Exchange phases are available in 1.7, 3, 5 and 10 µm non-porous particles sizes.
