Description
The Zodiac Phenyl column (250 mm × 4.6 mm, 5 µm) is a reversed-phase HPLC column featuring a phenyl-functionalized stationary phase, which is ideal for separating aromatic and moderately polar compounds. The phenyl group on the silica surface provides π-π interactions, making it particularly effective for analyzing aromatic compounds like Fexofenadine Hydrochloride and related impurities.
