Discovery Zr-PBD consists of spherical, porous zirconia particles with a durable coating of polybutadiene. It operates via reversed-phase and ion-exchange modes. Discovery Zr-PBD complements the selectivity offering of the other zirconia-, silica-, and polymer-based Discovery phases, and allows the use of the full range of mobile phase pH from pH 1 to 13.

Here's the
Proof
FAST, HIGH pH, HIGH TEMPERATURE SEPARATIONS
A significant difference between Discovery Zr-PBD and C18-silica is that it can be used with basic pH mobile phases and elevated temperatures where basic analytes have better peak shape and higher efficiency. This is demonstrated in the separation of basic antihistamine compounds in the figure below.
EXCELLENT FOR BASIC COMPOUNDS
Another example of the utility of Discovery Zr-PBD for basic compounds is shown in the separation of tricyclic antidepressants in the figure below.
