Prep Guard Column Cartridge, RP PFP, 5um, 100A. 30mm ID x 10mm Length. Cogent Brand. 1 EA.
Additional Info:
68522-P30-PG1 Cogent RP PFP™ Guard Column Cartridge is designed to protect large‑scale preparative HPLC columns from particulates and strongly retained contaminants that can degrade performance and shorten column life. Packed with 5 µm Cogent RP PFP™ material, this guard cartridge provides matched selectivity to the preparative column it protects.
The packing material 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. This ensures consistent chromatographic behavior and preserves method integrity during preparative separations.
Constructed in a robust stainless steel tube with stainless steel frits, this guard cartridge is engineered for durability under high‑flow preparative HPLC conditions.
30 mm ID × 10 mm Length – Large‑Scale Prep Column Protection
This guard column cartridge is optimized for use with 30 mm ID preparative columns, providing effective protection with minimal impact on flow or pressure.
Protects against particulates and strongly retained contaminants
Extends the lifespan of high‑value preparative columns
Maintains RP PFP selectivity during purification
✅ Recommended for large‑scale preparative workflows using 30 mm ID RP PFP columns
Flow Rate & System Requirements (30 mm ID, 5 µm)
⚠️ Requires preparative or purification HPLC system capability
Typical flow rate range: ~20 – 50 mL/min
Designed for very high‑flow preparative applications
Low additional backpressure relative to the main column
Compatible with large‑scale fraction collection systems
✅ Important: A specialized preparative HPLC system is required for columns of this size
✅ Required Hardware: Use with a 30 mm ID preparative guard column holder (see Guard Column Holder product page for compatibility and system requirements)
