Balanced HILIC Performance with Aromatic Selectivity in a Solvent‑Saver Phenyl Hydride™ Format
The 69020‑10P‑3 Phenyl Hydride™ HPLC Column is designed for laboratories seeking enhanced aromatic selectivity, improved resolution, and reduced solvent consumption using standard analytical HPLC systems. 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 format is frequently selected when moderate run times and higher resolution are required without the added solvent usage of wider‑bore analytical columns.
Why Choose Phenyl Hydride™ for HILIC Applications
Phenyl Hydride™ stationary phases combine classic HILIC retention with interaction mechanisms particularly well‑suited for aromatic compounds:
Strong retention of polar analytes under HILIC conditions
π–π and hydrophobic interactions that enhance separation of aromatic species
Improved resolution for analytes poorly retained in reversed‑phase separations
Fast equilibration and reproducible retention behavior
These characteristics make Phenyl Hydride an effective choice for 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 meaningful performance benefits:
Faster equilibration than bonded‑silica HILIC phases
Stable retention at high organic mobile‑phase composition
Reduced phase collapse and enhanced robustness
Extended column lifetime in routine analytical workflows
These properties support consistent separations with minimal re‑equilibration time.
Ideal Applications
The 69020‑10P‑3 Phenyl Hydride column is routinely used for:
Aromatic amines
Small peptides containing aromatic residues
Azides and heteroaromatic compounds
Polar analytes that are difficult to retain or resolve using reversed‑phase methods
It is especially valuable when aromatic selectivity improves separation confidence and method robustness.
3.0 mm ID Column for Resolution with Reduced Solvent Use
The 3.0 mm ID × 100 mm length configuration offers a practical balance of efficiency and economy:
Separation performance comparable to 4.6 mm ID columns
Significantly reduced mobile‑phase consumption
Lower operating flow rates with reduced backpressure
No requirement for specialized low‑flow or UHPLC equipment
This format is ideal for laboratories looking to lower solvent costs while maintaining familiar analytical workflows.
HPLC, UV, and LC‑MS Compatibility
This column is compatible with:
Conventional analytical HPLC systems
UV detection using standard flow cells
LC‑MS workflows where moderate analytical flow rates are preferred
The 3.0 mm internal diameter supports standard injection volumes and detector configurations without added system complexity.
Operating Guidelines and System Requirements
Typical flow‑rate range: ~0.4–0.6 mL/min (method‑dependent)
System compatibility: All conventional analytical HPLC systems
Special requirements: None; no low‑flow capability required
Flow rates may be optimized based on resolution goals, solvent composition, and system pressure limits.
