Catalog Number - 60022-10P

60022-10P 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 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 5 µm particle size, this column provides lower backpressure than smaller particle columns, allowing higher flow rates and robust, reproducible performance on standard analytical HPLC systems.

100 mm Length – Balanced Resolution and Efficiency

The 100 mm length provides an ideal balance between resolution and analysis time, making it suitable for routine testing and method development.

• Improved resolution compared to 50 mm columns

• Faster run times than 150 mm or 250 mm columns

• Increased peak capacity for moderately complex samples

✅ Recommended for QA/QC labs and general analytical workflows

Flow Rate & System Requirements (4.6 mm ID, 5 µm)

⚠️ Fully compatible with standard analytical HPLC systems with lower backpressure

• Typical flow rate range: ~1.0 – 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
