Catalog Number - 68004-PG2-3

Cogent RP C4 Butyl Wide Pore Guard Column Cartridges are packed with the same high-quality stationary phase used in Cogent RP C4 Wide Pore analytical columns. The 300 Å pore structure is designed for proteins, peptides, enzymes, and other large biomolecules, while the fully double endcapped butyl (C4) bonded phase provides reliable chromatographic performance and protection for biomolecule separations.

68004-PG2-3 is a guard column cartridge set packed with 10 µm RP C4 Butyl Wide Pore material with a 300 Å pore size in 4.0 mm ID x 10 mm length stainless steel cartridges. Designed for use with 3.0 mm, 4.0 mm, and 4.6 mm ID analytical HPLC columns, these cartridges help intercept particulates and strongly retained contaminants before they reach the analytical column bed. Regular guard cartridge replacement can help maintain consistent chromatographic performance and reduce analytical column replacement costs.

The wide pore RP C4 stationary phase is particularly well suited for protecting analytical columns used in protein, peptide, enzyme, and other large-molecule separations. Stainless steel cartridge construction with stainless steel frits and PEEK frit caps provides durability and reliable performance for routine HPLC and bioanalytical applications.
