Guard Column Cartridges, RP C18 Wide Pore, 5um, 300A. 2.1mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP C18™ Wide Pore Guard Column Cartridges are designed to protect valuable analytical HPLC columns from particulate matter, strongly retained contaminants, and sample matrix components that can shorten column life and reduce chromatographic performance. Packed with high-purity silica bonded with a traditional C18 (octadecyl) ligand and fully double end-capped chemistry, these guard cartridges provide the same chromatographic selectivity as the analytical column they protect while helping maintain method reproducibility and separation efficiency.
68518-PG1-3 is packed with 5 µm RP C18™ Wide Pore particles in a 2.1 mm ID x 10 mm guard cartridge format. The 300Å wide pore structure provides improved accessibility for proteins, peptides, biomolecules, and other larger molecular weight compounds. Designed specifically for use with 2.1 mm ID RP C18™ Wide Pore analytical columns, these guard cartridges are housed in stainless steel tubes with stainless steel frits pressed into durable PEEK frit caps for reliable performance and long service life.
Regular guard cartridge replacement can significantly reduce operating costs by protecting valuable analytical columns from contamination and premature failure. These guard cartridges are especially valuable for biopharmaceutical, protein, peptide, and other large molecule applications where protecting the analytical column helps maintain resolution, peak shape, and chromatographic reproducibility.
