Bond Elut CBA is a midpolarity sorbent and weak cation exchanger, ideal for strong cation analysis.

• Cation exchange with no need for extreme, basic conditions
• Wider selectivity range provides more eluent options
• Polar or nonpolar depending on matrix or solvent

Bond Elut CBA is a midpolarity sorbent and weak cation exchanger (pKa 4.8). It can be used with a wider range of counterions than lower pKa sorbents like SCX and enables easier elution of quaternary amine functionalized analytes.
