High‑Resolution HILIC Performance with Aromatic Selectivity Using Phenyl Hydride™
The 69020‑15P Phenyl Hydride™ HPLC Column is designed for laboratories requiring enhanced aromatic selectivity, robust retention, and increased resolving power for polar and aromatic compounds. Manufactured with Cogent TYPE‑C™ silica hydride technology, the Phenyl Hydride stationary phase delivers excellent selectivity, fast equilibration, and long column lifetime for analytes that are difficult to retain or separate using conventional reversed‑phase methods.
This column is a popular choice for HILIC‑mode separations, particularly when higher resolution and method robustness are required.
Why Choose Phenyl Hydride™ for HILIC Applications
Phenyl Hydride™ stationary phases combine classic HILIC retention with interaction mechanisms well‑suited for aromatic analytes:
Strong retention of highly polar compounds under HILIC conditions
π–π and hydrophobic interactions that enhance aromatic selectivity
Improved separation of analytes poorly retained in reversed‑phase systems
Fast equilibration and highly reproducible retention behavior
These characteristics make Phenyl Hydride an effective choice for both routine analysis and method development involving aromatic or heteroaromatic functionality.
Cogent TYPE‑C™ Silica Hydride Advantage
Phenyl Hydride™ columns are based on silica hydride surfaces rather than traditional silanol‑rich silica, providing important performance benefits:
Faster equilibration than bonded‑silica HILIC phases
Stable retention at high organic mobile‑phase content
Reduced phase collapse and improved robustness
Extended column lifetime in routine analytical workflows
These features support consistent performance across extended analytical sequences.
Ideal Applications
The 69020‑15P Phenyl Hydride column is routinely used for:
Aromatic amines
Small peptides containing aromatic residues
Azides and heteroaromatic compounds
Small, very polar analytes analyzed under HILIC conditions
It is especially valuable when aromatic selectivity and high resolution are needed to confidently resolve closely eluting compounds.
150 mm Column Length for Increased Resolution
The 4.6 mm ID × 150 mm length configuration provides:
Higher plate count and improved separation of closely eluting compounds
Greater method robustness compared to shorter columns
Reliable performance for routine and regulated analytical workflows
This column length is often selected when shorter formats do not provide sufficient resolution, particularly for complex mixtures.
HPLC and UV Detection Compatibility
This column is fully compatible with:
Conventional analytical HPLC systems
UV detection using standard flow cells
The 4.6 mm internal diameter supports traditional injection volumes and detector configurations without requiring specialized low‑dead‑volume hardware.
Operating Guidelines and System Requirements
Typical flow‑rate range: ~0.8–1.5 mL/min (method‑dependent)
System compatibility: All conventional analytical HPLC systems
Special requirements: None
Flow rates may be optimized based on resolution requirements, solvent composition, and system pressure limits.
