These specially deactivated columns differ in that Suplex pKb-100 is not endcapped, while SUPELCOSIL LC-ABZ is endcapped. The absence of the end-capping reagent results in better performance from Suplex pKb-100 for the strongest basic compounds, while LC-ABZ is preferred when the sample also contains acids and/or zwitterions.
