Prep Guard Column Cartridge, RP Phenyl, 10um, 100A. 21.2mm ID x 10mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP Phenyl Guard Column Cartridges are packed with the same C3-phenyl bonded stationary phase used in Cogent RP Phenyl 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 and structurally related compounds.
68024-P21-PG1 is a preparative guard column cartridge packed with 10 µm RP Phenyl particles featuring a 100 Å pore size in a 21.2 mm ID x 10 mm format. Installed ahead of the analytical bed, the cartridge helps trap particulates, strongly retained contaminants, and sample matrix components before they reach the preparative column. This protection helps preserve column efficiency, maintain reproducible results, and extend the service life of the primary column.
The cartridge is housed in durable stainless steel hardware with stainless steel frits and is intended for use with compatible 21.2 mm ID RP Phenyl preparative columns. Matching stationary phase chemistry helps maintain chromatographic performance while reducing the impact of contaminated samples and demanding purification workflows.
