Guard Column Cartridges, RP Cyano Wide Pore, 5um, 300A. 4.0mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP Cyano™ Wide Pore Guard Column Cartridges are designed to protect analytical HPLC columns from particulates, strongly retained compounds, and other contaminants that can reduce column performance and shorten column life. Packed with the same stationary phase as the analytical column, these guard cartridges help maintain chromatographic performance while reducing the frequency and cost of analytical column replacement.
68534-PG2-3 is packed with 5 µm RP Cyano™ Wide Pore stationary phase featuring a 300Å pore size. Manufactured using ultra-high purity silica bonded with a three-carbon ligand and terminal Cyano functionality, this stationary phase is not end capped and provides the distinctive selectivity associated with USP L10 chemistry. The wide pore structure improves accessibility for larger molecules while maintaining the unique separation characteristics of RP Cyano™ chemistry. The cartridges are packed and shipped in reversed-phase solvents and housed in stainless steel tubing with stainless steel frits secured within durable PEEK frit caps.
The 4.0 mm ID x 10 mm format is designed to protect 3.0 mm, 4.0 mm, and 4.6 mm ID RP Cyano™ Wide Pore analytical HPLC columns from particulate contamination and strongly retained sample components. Routine guard cartridge replacement helps maintain column efficiency, reduce downtime, and extend analytical column service life.
