Bond Elut CBA


Ion Exchange Silica SPE
CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4.8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX, and will demonstrate easier elution of quaternary amine functionalized analytes.

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