HPLC Column, RP PFP, 10um, 4.6mm ID x 150mm Length, 100A. Cogent Brand. 1 EA.
Additional Info:
68022-15P Cogent RP PFP™ HPLC Column has been a premium value trusted by HPLC laboratories for many years, delivering consistent performance and enhanced selectivity for a wide range of analytical separations. This column is fully double end‑capped and bonded via a four‑carbon linker to a benzene ring substituted with five fluorine atoms, using ultra‑high purity silica.
The column enables multiple retention mechanisms—including π‑π interactions, dipole interactions, and hydrogen bonding—making it especially effective for halogenated, aromatic, and polar analytes. It is also suitable as an alternate column for USP methods requiring L43 classification.
With a 10 µm particle size, this column provides very low backpressure compared to smaller particle columns, allowing higher flow rates and improved system compatibility, particularly for systems with pressure limitations.
150 mm Length – Enhanced Resolution with High Flow Capability
The 150 mm length delivers improved resolving power compared to shorter columns while maintaining low backpressure operation.
Higher resolution than 50 mm and 100 mm columns
Improved separation of closely related compounds
Increased peak capacity for moderately complex samples
✅ Recommended for analytical workflows requiring improved resolution with higher flow flexibility
Flow Rate & System Requirements (4.6 mm ID, 10 µm)
⚠️ Designed for high‑flow, low‑pressure operation
Typical flow rate range: ~1.0 – 2.0 mL/min
Very low backpressure compared to 5 µm and 3 µm columns
Supports higher flow rates without exceeding system limits
Compatible with UV and standard analytical detectors
✅ Best Practice: Filter samples using a 0.2 µm syringe filter prior to injection
