Prep HPLC Column, RP PFP, 5um, 100A. 30mm ID x 100mm Length. Cogent Brand. 1 EA.
Additional Info:
68522-P30-100 Cogent RP PFP™ Prep HPLC Column has been a premium value trusted by HPLC laboratories for many years, delivering consistent performance and enhanced selectivity for preparative and scale‑up 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 high purity 100 Å 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. These mechanisms improve separation of structurally similar compounds, which is critical for ensuring purity in large‑scale preparative workflows.
With a 5 µm particle size, this column supports very high flow rates typical of 30 mm preparative systems while maintaining strong separation efficiency and controlled backpressure.
100 mm Length – Balanced Resolution for Large‑Scale Purification
The 100 mm length provides an ideal balance between throughput and resolving power in high‑capacity preparative workflows.
Improved resolution compared to 50 mm columns
Faster cycle times than longer preparative formats
Increased peak capacity for moderately complex mixtures
✅ Recommended for routine large‑scale purification and process development
Flow Rate & System Requirements (30 mm ID, 5 µm)
⚠️ Requires preparative or process‑scale HPLC system capability
Typical flow rate range: ~20 – 50 mL/min
Designed for very high‑flow preparative operation
Moderate backpressure relative to column size
Compatible with large‑scale fraction collection systems
✅ Important: A specialized preparative or process HPLC system is required for columns of this size
✅ Best Practice: Use appropriate sample filtration and a matched RP PFP guard column cartridge to protect the column and maintain performance
