Prep Guard Column Cartridge, RP Phenyl Wide Pore, 10um, 300A. 21.2mm ID x 10mm Length. Cogent Brand. 1 EA.
Additional Information:
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 C18 or C8 phases do not provide sufficient resolution of aromatic, structurally related, or larger molecular weight compounds.
68024-P21-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 21.2 mm ID x 10 mm format. Installed ahead of the preparative column, the cartridge helps capture particulates, strongly retained contaminants, and sample matrix components before they reach the analytical bed. This protection helps maintain column efficiency, improve reproducibility, and extend the service life of the primary column.
The wide pore design is particularly suitable for larger molecules and peptide-related applications while maintaining RP Phenyl selectivity. The cartridge is constructed from stainless steel tubing with stainless steel frits and is designed for use with compatible 21.2 mm ID RP Phenyl Wide Pore preparative columns.
