Guard Column Cartridges, RP C18, 5um, 100A. 2.1mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP C18™ 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 is packed with 5 µm RP C18™ particles in a 2.1 mm ID x 10 mm guard cartridge format. Designed specifically for use with 2.1 mm ID RP C18™ analytical columns, these guard cartridges are housed in stainless steel tubes with stainless steel frits pressed into durable PEEK frit caps. They capture particulates and strongly retained compounds before they reach the analytical column, helping preserve column performance and extend 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 ideal for pharmaceutical, environmental, food, biotechnology, clinical, and research laboratories that require reliable reversed-phase HPLC performance and maximum column longevity.
