Guard Column Cartridges, RP Phenyl, 10um, 100A. 4.0mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP Phenyl Guard Column Cartridges are packed with the same C3-phenyl bonded stationary phase used in Cogent RP Phenyl analytical 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 and structurally related compounds.
68024-PG2 is a guard column cartridge packed with 10 µm RP Phenyl particles featuring a 100 Å pore size in a 4.0 mm ID x 10 mm format. Installed ahead of the analytical column, the cartridge captures 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.
These guard cartridges are designed for use with 3.0 mm, 4.0 mm, and 4.6 mm ID Cogent RP Phenyl analytical columns. Each cartridge is packed in a stainless steel tube and fitted with stainless steel frits in PEEK end caps for durability and reliable performance in routine laboratory applications.
