Guard Column Cartridges, RP Phenyl, Wide Pore, 10um, 300A. 4.0mm ID x 10mm Length. Cogent Brand. 5/PK.
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 analytical columns. Manufactured with high-purity silica and exhaustive double endcapping, these cartridges provide aromatic selectivity through π-π interactions while helping maintain consistent chromatographic performance throughout the life of the analytical column.
68024-PG2-3 is a guard column cartridge packed with 10 µm RP Phenyl Wide Pore particles featuring a 300 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 preserve column efficiency, improve reproducibility, and extend analytical column lifetime.
The 300 Å wide pore design is particularly suitable for larger molecules, peptides, proteins, and other high molecular weight analytes. These cartridges are designed for use with 3.0 mm, 4.0 mm, and 4.6 mm ID Cogent RP Phenyl Wide Pore 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.
