Fast HILIC Performance with Aromatic Selectivity in a Solvent‑Saver Phenyl Hydride™ Format
The 69020‑05P‑3 Phenyl Hydride™ HPLC Column is engineered for laboratories requiring rapid HILIC separations, enhanced aromatic selectivity, and reduced solvent consumption using conventional 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 resolve using traditional reversed‑phase methods.
This column is particularly effective for compounds where aromatic or heteroaromatic functionality plays a critical role in chromatographic behavior.
Why Choose Phenyl Hydride™ for HILIC Applications
Phenyl Hydride™ columns provide a unique interaction profile that combines classic HILIC retention with additional selectivity for aromatic analytes:
Strong retention of polar analytes under HILIC conditions
π–π and hydrophobic interactions that enhance separation of aromatic compounds
Improved resolution for analytes poorly retained by reversed‑phase columns
Fast equilibration and highly reproducible retention behavior
These properties make Phenyl Hydride an excellent choice for both routine analysis and method‑development workflows where aromatic selectivity is required.
Cogent TYPE‑C™ Silica Hydride Advantage
The Phenyl Hydride stationary phase is based on silica hydride surfaces rather than conventional silanol‑rich silica, providing important performance benefits:
Faster equilibration compared to bonded‑silica HILIC phases
Stable retention mechanisms at high organic mobile‑phase content
Reduced phase collapse and improved robustness
Extended column lifetime for routine analytical use
These characteristics support high reliability and minimal downtime in demanding laboratory environments.
Ideal Applications
The 69020‑05P‑3 Phenyl Hydride column is routinely selected for:
Aromatic amines
Small peptides containing aromatic residues
Azides and heteroaromatic compounds
Polar analytes that are difficult to retain or separate using reversed‑phase methods
It is especially valuable when additional aromatic selectivity improves separation confidence.
3.0 mm ID “Solvent‑Saver” Column for Fast Analysis
The 3.0 mm ID × 50 mm length configuration offers several practical advantages:
Run times comparable to standard 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 seeking improved efficiency and solvent savings while maintaining straightforward system compatibility.
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 the constraints associated with narrow‑bore columns.
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 needs, solvent composition, and system pressure limits.
