Semi Prep Guard Column Cartridge, RP Phenyl, Wide Pore, 10um, 300A. 10mm 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 semi-preparative columns. Manufactured with high-purity silica and exhaustive double endcapping, these cartridges provide aromatic selectivity through π-π interactions while helping maintain chromatographic performance and extending the life of the primary column.
68024-SP-PG1-3 is a semi-preparative guard column cartridge packed with 10 µm RP Phenyl Wide Pore particles featuring a 300 Å pore size in a 10 mm ID x 10 mm format. Installed ahead of the primary 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 column lifetime.
The 300 Å pore structure is especially suitable for larger molecules, peptides, proteins, and other high molecular weight analytes. Constructed from stainless steel tubing with stainless steel frits, these guard cartridges are designed for use with compatible 10 mm ID RP Phenyl Wide Pore semi-preparative columns.
