HPLC Column, Diamond Hydride 2.o, 2.2 um, 2.1 x 50 mm Length, 120 A. Cogent TYPE-C Brand. 1 EA.
Additional Info:
The 70200‑05P‑2 Diamond Hydride 2.0 HPLC Column is engineered for fast, high‑efficiency HILIC separations, making it an excellent choice for LC‑MS applications where speed, sensitivity, and rapid equilibration are critical.
Why Choose the 2.1 mm × 50 mm Format
This short, narrow‑bore configuration is optimized for:
Rapid run times and high sample throughput
Fast equilibration between injections
Efficient use of solvent and reduced waste
The 50 mm column length provides quick separations while the 2.1 mm internal diameter supports LC‑MS workflows by reducing solvent flow into the mass spectrometer.
Diamond Hydride™ 2.0 Stationary Phase Advantages
Built on Cogent TYPE‑C™ silica hydride technology, the Diamond Hydride 2.0 stationary phase delivers:
Excellent retention and selectivity for polar and moderately polar analytes
Faster equilibration than traditional bonded‑silica HILIC phases
Stable and reproducible performance across complex mobile‑phase compositions
This column is particularly effective for:
Polar and non‑polar peptides
Amino acids
Metabolites and small biomolecules
Other challenging compounds analyzed using HILIC methods
The smaller 2.2 µm particle size contributes to near‑UHPLC separation efficiency, without requiring UHPLC‑rated pressures under typical operating conditions.
LC‑MS Focused Performance
The reduced column volume and lower operating flows make this column a popular choice for LC‑MS and LC‑MS/MS workflows, helping improve ionization efficiency while maintaining sharp peak shapes and reliable resolution.
System Requirements
Typical operating flow rates: ~0.2–0.3 mL/min
Requires an HPLC system capable of accurate, stable low‑flow delivery
Not all standard HPLC pumps are suitable for reliable operation at these flow rates
Flow‑rate optimization may be further refined based on mobile‑phase viscosity, column temperature, and system pressure limits.
