Prep Guard Column Cartridge, RP PFP, 10um, 100A. 30mm ID x 10mm Length. Cogent Brand. 1 EA.
Additional Info:
68022-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 column performance and shorten operational life. Packed with 10 µm Cogent RP PFP™ material, this guard cartridge provides matched selectivity with minimal added backpressure.
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 chromatography and preserves separation integrity during high‑flow preparative operations.
Constructed in a durable stainless steel tube with stainless steel frits, this cartridge is engineered to withstand the demanding pressures and flow rates of large‑scale purification systems.
30 mm ID × 10 mm Length – Large‑Scale Prep Column Protection
Designed specifically for 30 mm ID preparative columns, this guard cartridge minimizes contamination while maintaining system efficiency.
Protects against particulates and sample matrix fouling
Extends lifespan of high-value prep columns
Preserves RP PFP selectivity in purification workflows
✅ Recommended for large‑scale preparative workflows using 30 mm ID RP PFP columns
Flow Rate & System Requirements (30 mm ID, 10 µm)
⚠️ Requires preparative or process-scale HPLC system capability
Typical flow rate range: ~20 – 60 mL/min
Extremely low backpressure due to 10 µm particle size
Designed for very high‑flow preparative operation
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 specifications)
