CUSTOM ITEM: HPLC Column, RP PFP, 5um, 4.0mm ID x 150mm Length, 100A. Cogent Brand. 1 EA.
Additional Info:
68522-15P-4 Cogent RP PFP™ HPLC Column has been a premium value trusted by HPLC laboratories for many years, delivering reliable performance and enhanced selectivity for complex 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 provides multiple retention mechanisms—including π‑π interactions, dipole interactions, and hydrogen bonding—making it highly effective for halogenated, aromatic, and polar analytes. It is also suitable as an alternate column for USP methods requiring L43 classification.
With a 5 µm particle size, this column offers lower backpressure than smaller particle columns, allowing higher flow rates and robust, reproducible performance in standard analytical HPLC systems.
150 mm Length – Enhanced Resolution for Analytical Separations
The 150 mm length provides increased resolving power, making it well suited for more complex separations requiring improved peak separation.
Higher resolution than shorter column formats
Improved separation of closely related analytes
Increased peak capacity for complex mixtures
✅ Recommended for analytical workflows requiring reliable and consistent resolution
Flow Rate & System Requirements (4.0 mm ID, 5 µm)
⚠️ Compatible with standard analytical HPLC systems with moderate backpressure
Typical flow rate range: ~0.8 – 1.5 mL/min
Lower backpressure than 3 µm columns
Supports stable, higher flow rate operation
Compatible with UV and standard detectors
✅ Best Practice: Filter samples using a 0.2 µm syringe filter prior to injection
