Prep Guard Column Cartridge, RP C4, 10um, 100A. 21.2mm ID x 10mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C4 Butyl Guard Column Cartridges are packed with the same high-quality stationary phase used in Cogent RP C4 preparative columns, featuring traditional butyl (C4) ligand bonding on high-purity silica with complete double endcapping. These guard cartridges are designed to capture particulates, strongly retained contaminants, and sample matrix components before they reach the analytical bed of the preparative column, helping extend column life and maintain chromatographic performance.
68004-P21-PG1 is a preparative guard column cartridge packed with 10 µm RP C4 Butyl material with a 100 Å pore size in a 21.2 mm ID x 10 mm length stainless steel cartridge. Designed specifically for use with 21.2 mm ID preparative columns, this guard cartridge provides an economical way to protect valuable preparative columns from contamination and premature fouling. Regular guard cartridge replacement can help reduce downtime, improve reproducibility, and lower overall column operating costs.
This guard cartridge should be used with a 21.2 mm ID Preparative Guard Column Holder, which is required for installation and operation. For compatibility and ordering details, see the Cogent 21.2 mm ID Preparative Guard Column Holder (83000-P21-GH). The RP C4 stationary phase is ideal for protecting preparative columns used in purification of hydrophobic and neutral compounds where sample matrices or process streams may introduce contaminants that can shorten column lifetime.
