Guard Column Cartridges, RP Cyano Wide Pore, 10 um, 300 A. 4.0 mm ID x 10 mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP Cyano Wide Pore Guard Column Cartridges are packed with the same cyanopropyl (CN) bonded stationary phase used in Cogent RP Cyano Wide Pore analytical columns. Manufactured with high-purity silica and a 3-carbon linker terminated with a cyano functional group, these guard cartridges provide the same USP L10 selectivity as the analytical column while protecting it from contamination and premature fouling. The 300 Å pore structure improves accessibility for larger molecules such as peptides, proteins, enzymes, and other biomolecules.
68034-PG2-3 is a guard column cartridge packed with 10 µm RP Cyano Wide Pore particles featuring a 300 Å pore size in a 4.0 mm ID x 10 mm format. Installed ahead of the analytical column, it captures particulates, strongly retained contaminants, and sample matrix components before they reach the primary analytical bed. This protection helps maintain chromatographic performance, improve reproducibility, and extend analytical column lifetime.
These guard cartridges are designed for use with 3.0 mm, 4.0 mm, and 4.6 mm ID Cogent RP Cyano Wide Pore analytical columns. Each cartridge is packed in reversed-phase solvent and housed in a stainless steel tube with stainless steel frits pressed into durable PEEK frit caps for reliable long-term performance.
