Discovery Zr-PS HPLC columns
Features and Benefits
Discovery® Zr-PS comprises spherical, porous zirconia particles modified with cross-linked polystyrene. It operates via a reversed-phase mechanism, but is less retentive. It has unique selectivity, especially for aromatic compounds. Discovery Zr-PS complements the selectivity offering of the other zirconia- and silica-based Discovery phases, and allows the use of the full range of mobile phase pH from pH 1 to 13.
