Semi Prep Guard Column Cartridge, RP PFP, 10um, 100A. 10mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Info:
68022-SP-PG1 Cogent RP PFP™ Guard Column Cartridge is designed to protect semi‑prep HPLC columns from particulates and strongly retained contaminants that can reduce column performance and lifespan. Packed with 10 µm Cogent RP PFP™ material, this guard cartridge matches the selectivity of the analytical and semi‑prep PFP columns it supports.
This column utilizes a fully double end‑capped surface bonded via a four‑carbon linker to a benzene ring substituted with five fluorine atoms, using high purity 100 Å silica. This chemistry provides consistent retention behavior and ensures compatibility with RP PFP analytical methods.
Each cartridge is packed in a durable stainless steel tube with stainless steel frits, providing strength and performance under semi‑prep and higher flow conditions.
