Additional Info:
Fast HILIC Performance with Aromatic Selectivity Using Phenyl Hydride™
The 69020‑75P Phenyl Hydride™ HPLC Column is designed for laboratories requiring rapid HILIC separations with reliable aromatic selectivity using conventional 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 traditional reversed‑phase methods.
The 75 mm column length provides an effective balance between speed and resolution for routine analytical and method‑screening workflows.
Why Choose Phenyl Hydride™ for HILIC Applications
Phenyl Hydride™ stationary phases combine 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 a dependable choice for both routine analysis and early‑stage method development involving aromatic or heteroaromatic compounds.
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 performance with minimal equilibration time between injections.
Ideal Applications
The 69020‑75P 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 particularly useful when fast results are needed without sacrificing selectivity.
75 mm Column Length for Speed‑Focused Separations
The 4.6 mm ID × 75 mm length configuration offers:
Short analysis times compared to longer analytical columns
Improved resolution relative to 50 mm formats for closely eluting compounds
Robust performance for high‑throughput screening and method optimization
This format is often selected when rapid turnaround is a priority but some additional resolving power is required.
HPLC and UV Detection Compatibility
This column is compatible with:
Conventional analytical HPLC systems
UV detection using standard flow cells
The 4.6 mm internal diameter supports common injection volumes and detector configurations without requiring specialized 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 speed, resolution needs, and system pressure limits.
