High‑Resolution HILIC Performance with Aromatic Selectivity in a Solvent‑Saver Phenyl Hydride™ Format
The 69020‑15P‑3 Phenyl Hydride™ HPLC Column is designed for laboratories seeking enhanced aromatic selectivity, increased resolving power, 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 robust column lifetime for compounds that are difficult to retain or separate using conventional reversed‑phase methods.
This column format is commonly selected when higher resolution is required, while maintaining efficient operation and lower mobile‑phase usage.
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 polar compounds under HILIC conditions
π–π and hydrophobic interactions that enhance separation of aromatic species
Improved resolution for 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 key 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 69020‑15P‑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 added aromatic selectivity improves resolution and analytical confidence.
3.0 mm ID Column for Resolution with Reduced Solvent Use
The 3.0 mm ID × 150 mm length configuration offers a practical balance of resolution and efficiency:
Higher resolving power than shorter columns
Reduced solvent consumption compared to 4.6 mm ID analytical columns
Lower operating flow rates with reduced backpressure
No requirement for specialized low‑flow or UHPLC equipment
This format supports robust workflows while lowering solvent usage and operating costs.
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 additional 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
Flow rates may be optimized based on resolution goals, solvent composition, and system pressure limits.
