Clean-Up® Cation Exchange Columns
This sorbent is composed of a silica backbone bonded with a carbon chain terminated by a negatively or positively charged functional group. Ion exchange interactions occur between a sorbent that carries a charge and a compound of opposite charge. This electrostatic interaction is reversible by neutralizing the sorbent and /or analyte. Ion exchange bonds can also be disrupted by introduction of a “counter ion” to compete with…

This sorbent is composed of a silica backbone bonded with a carbon chain terminated by a negatively or positively charged functional group.
Ion exchange interactions occur between a sorbent that carries a charge and a compound of opposite charge. This electrostatic interaction is reversible by neutralizing the sorbent and /or analyte. Ion exchange bonds can also be disrupted by introduction of a “counter ion” to compete with the analyte for binding sites on the sorbent.
UCT offers a variety of both weak and strong cation exchange columns. Sorbent functionalities include carboxylic acid, propylsulfonic acid, triacetic acid, and benzenesulfonic acid.
