CUSTOM ITEM: HPLC Column, Diamond Hydride, 4um, 3.0 mm ID x 150 mm Length, 100 A. Cogent TYPE-C Brand. 1 EA.
Additional Info:
The 70000‑15P‑3 Diamond Hydride HPLC Column is a solvent‑saver analytical column designed for laboratories seeking the resolving power of longer analytical columns while significantly reducing mobile‑phase consumption. Built on proven Cogent TYPE‑C™ silica hydride technology, this column delivers reliable retention, fast equilibration, and extended column lifetime for polar and mixed‑polarity analytes.
The 3.0 mm × 150 mm format provides increased plate count and resolution comparable to traditional 4.6 mm ID analytical columns, while operating at lower flow rates and reduced solvent usage.
This item is custom and can be manufactured to order.
Why This Column Is Used
The 3.0 mm internal diameter is widely recognized as a solvent‑saving alternative to standard analytical HPLC columns. This configuration offers:
Substantially lower solvent consumption than 4.6 mm ID columns
Resolution comparable to traditional analytical formats
Reduced operating costs for routine and high‑volume use
Compatibility with standard HPLC and LC‑MS systems
The 150 mm length provides enhanced separation efficiency for complex polar mixtures, making this column well suited for method development, validation, and regulated workflows.
Diamond Hydride™ Stationary Phase Advantage
Manufactured using Cogent TYPE‑C™ silica hydride technology, the Diamond Hydride stationary phase offers clear advantages over conventional bonded‑silica HILIC columns:
Faster equilibration, reducing overall method cycle times
Stable and reproducible retention, even with high organic content
Long column lifetime suitable for routine analytical use
The silica hydride surface supports mixed‑mode interactions, enabling effective separation of analytes not well retained by traditional reversed‑phase columns.
Typical Applications
This column is routinely used for:
Small, highly polar molecules
Amino acids and organic acids
Polar and mixed‑polarity peptides
Metabolites and biologically relevant compounds
Routine HILIC and mixed‑mode analytical workflows
High‑Efficiency, Solvent‑Saving Performance
The combination of a 150 mm length and 3.0 mm internal diameter makes this column particularly effective for:
Applications where higher resolution is required
Laboratories seeking to reduce solvent consumption and waste
Methods transitioning from 4.6 mm ID columns without loss of performance
This format allows laboratories to maintain analytical rigor while improving operational efficiency.
System Requirements
Typical operating flow rates: ~0.4–0.6 mL/min, depending on mobile‑phase viscosity and method conditions
Compatible with conventional analytical HPLC and LC‑MS systems
No specialized low‑flow hardware required
Flow rates may be further optimized based on resolution targets, pressure limits, and detector configuration.
