Semi Prep Guard Column Cartridge, NP Silica Wide Pore, 5um, 300A. 10mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent NP Silica™ Wide Pore Semi-Preparative Guard Column Cartridges are designed to protect semi-preparative HPLC columns from particulate contamination and strongly retained compounds that can reduce column performance and shorten column life. Packed with the same high-purity stationary phase as the analytical column, these guard cartridges help maintain chromatographic performance while reducing replacement costs for valuable semi-preparative columns.
82561-SP-PG1-3 Guard Column Cartridges are packed with 5 µm NP Silica™ Wide Pore stationary phase manufactured from ultra-high purity, low-metal-content 300 Å silica. This unmodified silica stationary phase provides traditional USP L3 selectivity while the wide pore structure improves accessibility for proteins, peptides, and other larger biomolecules. Packed in stainless steel cartridges with stainless steel frits, they are designed to intercept contaminants before they reach the primary separation column.
The 10 mm ID x 10 mm format is specifically designed for use with compatible 10 mm ID semi-preparative column systems operating in HILIC and normal-phase modes. Routine guard cartridge replacement helps maintain column efficiency, reduce downtime, and extend semi-preparative column service life.
