Cole-Parmer® Diphenyl HPLC & UHPLC Columns and Accessories

Provides extra retention of compounds containing aromatic functionality
  • Unique selectivity
  • Enhanced polar retention
  • Fast separations with excellent resolution and sensitivity
  • Stable hydrophobic ligand—no observable "MS-bleed"
Diphenyl columns are based upon a unique di-phenyl functionality to offer high selectivity, sharp peak shapes, and enhanced resolution. The extended selectivity allows to discriminate between very closely related species, such as those often associated as metabolites or excipients. Columns offer a stable bonding process since the alkyl chain ligand removes the dipolar phenol/silica interactions.

Columns come in 316L stainless steel (SS) tubing hardware. A SS female end fitting with a SS and PEEK frit system keeps the stationary phase in place and packed bed from disturbance. The SS end fitting accepts a male 10-32 threaded nut with standard 1/16" OD tubing.

Use the guard cartridges to maintain chromatographic integrity. They ensure erroneous materials are kept out of the more important and expensive analytical columns, leading to more accurate results. Simply match the sizes to select the correct guard cartridge for your column; guard cartridge holder 16470-89 is required to use the guard cartridges. In-line filters are available for your UPHLC and HPLC columns—order separately.
