Additional Info:
High‑Resolution HILIC Performance with Aromatic Selectivity in a Solvent‑Saver Phenyl Hydride™ Format
The 69020‑25P‑3 Phenyl Hydride™ HPLC Column is designed for laboratories seeking high resolving power, enhanced aromatic selectivity, and reduced solvent consumption using standard analytical HPLC systems. Manufactured with Cogent TYPE‑C™ silica hydride technology, the Phenyl Hydride stationary phase provides 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 increased separation 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, even for extended analyses.
Ideal Applications
The 69020‑25P‑3 Phenyl Hydride column is routinely used for:
Aromatic amines
Small peptides containing aromatic residues
Azides and heteroaromatic compounds
Polar analytes that require enhanced resolution under HILIC conditions
It is especially valuable when closely related aromatic compounds demand confident separation.
3.0 mm ID Column for Resolution with Reduced Solvent Use
The 3.0 mm ID × 150 mm length configuration provides a practical balance of resolution and efficiency:
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 supports robust analytical 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 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
Flow rates may be optimized based on resolution needs, solvent composition, and system pressure limits.
