Features and Benefits

For acids, bases, zwitterions Increased polar retention relative to standard reversed-phases Unique selectivity Silanol deactivation Peak shape, efficiency, and retention are comparable to C8 phases for non-polar analytes

General description

SUPELCOSIL LC-ABZ phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar. Silanol suppressing practices such as using competing amines, operating at high ionic strength, and adjusting mobile phases to pH extremes are typically not required to obtain good peak shape on the LC-ABZ phase.
