Discovery Zr-PBD HPLC columns
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.
Particle:   Zirconia (ZrO2)
Bonded Phase:   Polybutadiene
Particle Shape:   Spherical
Particle Size:   3 and 5µm
Pore Size:   300Å
Surface Area:   30m2/g
pH Range:   1 to 13
Temperature Range:   up to 100°C in standard hardware (up to 150°C in custom all-steel hardware)
Unique retention and selectivity for method development at pH and temperature extremes

Good for bases, amines

Similar to ODS-silica

pH stable from 1-13

Thermally stable up to 100°C or higher

Here's the
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.

Another example of the utility of Discovery Zr-PBD for basic compounds is shown in the separation of tricyclic antidepressants in the figure below.
