CUSTOM ITEM: HPLC Column, Amide, 4um, 3.0mm ID x 150mm Length, 100A. Cogent TYPE-C Brand. 1 EA.
Additional Info:
The 40036‑15P‑3 Amide HPLC Column is manufactured using Cogent TYPE‑C™ silica hydride technology, delivering excellent selectivity, faster equilibration, and robust column lifetime for HILIC separations. The amide stationary phase provides strong, reproducible interaction with amine‑containing and highly polar analytes, while the silica‑hydride surface reduces moisture‑layer variability commonly associated with conventional amide‑bonded silica columns.
This column is produced as a custom, made‑to‑order item and is designed for laboratories seeking higher resolution with improved solvent efficiency without requiring specialized low‑flow instrumentation.
Application Focus: Amide Chemistry for HILIC Separations
Amide stationary phases are particularly effective for highly polar analytes requiring stable and reproducible HILIC retention. The Amide phase is commonly selected for:
Sugars and sugar alcohols
Amine‑containing compounds
Polar metabolites
Other HILIC‑appropriate polar analytes
The TYPE‑C™ silica hydride backbone supports consistent retention and improved reproducibility compared to traditional amide‑bonded silica phases, especially under high‑organic mobile‑phase conditions.
Key Advantages of Cogent TYPE‑C™ Amide Technology
Compared to conventional amide HILIC columns, this column provides:
Faster equilibration between injections
Improved retention stability across mobile‑phase compositions
Robust column lifetime under demanding HILIC conditions
Reduced moisture sensitivity, improving run‑to‑run consistency
These advantages make the Amide TYPE‑C™ column suitable for both routine analysis and advanced method development.
Why Choose the 3.0 mm × 150 mm Format
The 3.0 mm ID × 150 mm length configuration offers a balance between high resolving power and solvent efficiency:
Run times similar to 4.6 mm ID columns
Lower operating flow rates, reducing mobile‑phase consumption
Lower backpressure than narrow‑bore formats
Compatible with standard analytical HPLC systems, with no specialized low‑flow equipment required
This format is ideal when extended resolution is needed but laboratories prefer to avoid the solvent demands of larger‑diameter columns.
Particle Size and Performance
The 4 µm particle size delivers reliable efficiency and peak shape with manageable backpressure, supporting consistent performance on standard analytical HPLC platforms.
System Requirements and Flow Rates
Typical flow range (3.0 mm ID): ~0.4–0.6 mL/min
System capability: Compatible with standard analytical HPLC systems
Note: No specialized low‑flow or UHPLC‑only equipment is required
Final flow rates should be optimized based on mobile‑phase viscosity, column temperature, and system pressure limits.
