Catalog Number - 68024-P30-PG1-3

Cogent RP Phenyl Wide Pore Guard Column Cartridges are packed with the same C3-phenyl bonded stationary phase used in Cogent RP Phenyl Wide Pore preparative columns. Manufactured with high-purity silica and exhaustive double endcapping, these cartridges provide the aromatic selectivity and π-π interaction characteristics that make RP Phenyl an effective choice when separating aromatic, structurally related, and larger molecular weight compounds.

68024-P30-PG1-3 is a preparative guard column cartridge packed with 10 µm RP Phenyl Wide Pore particles featuring a 300 Å pore size in a 30 mm ID x 10 mm format. Installed ahead of the preparative column, the cartridge helps trap particulates, strongly retained contaminants, and sample matrix components before they reach the analytical bed. This protection helps preserve column efficiency, improve reproducibility, and extend the service life of the primary column.

The 300 Å pore structure is well suited for larger molecules and peptide-related applications while maintaining RP Phenyl selectivity. Constructed from stainless steel tubing with stainless steel frits, this guard cartridge is designed for use with compatible 30 mm ID RP Phenyl Wide Pore preparative columns.
