Guard Column Cartridges, RP Cyano, 10um, 100A. 4.0mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP Cyano Guard Column Cartridges are packed with the same cyanopropyl (CN) bonded stationary phase used in Cogent RP Cyano 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 non-endcapped chemistry offers the characteristic retention profile and selectivity that make RP Cyano valuable for polar and neutral compound separations.
68034-PG2 is a guard column cartridge packed with 10 µm RP Cyano particles featuring a 100 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 analytical columns. Each cartridge is packed in reversed-phase solvents and housed in a stainless steel tube with stainless steel frits pressed into durable PEEK frit caps for reliable long-term operation.
