Guard Column Cartridges, Nova Similars C18, 4um. 4.0mm x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent Nova Similars C18™ Guard Column Cartridges are packed with fully endcapped 4 µm C18 stationary phase bonded to high-purity spherical silica with a 200Å pore size. Designed to provide chromatographic compatibility with Nova Similars C18 analytical columns, these guard cartridges help protect expensive analytical columns from particulate contamination, strongly retained compounds, and sample matrix components that can reduce column lifetime and performance.
64418-PG2 guard cartridges are sized 4.0 mm x 10 mm and are recommended for use with 3.0 mm, 4.0 mm, and 4.6 mm ID Cogent Nova Similars C18 analytical columns. By trapping contaminants before they reach the analytical column, these cartridges help maintain chromatographic efficiency, preserve peak shape, reduce downtime, and lower long-term operating costs. Each cartridge is packed in a stainless steel body with stainless steel frits secured in durable PEEK frit caps for reliable performance in HPLC applications.
Regular replacement of guard cartridges can significantly extend analytical column life, particularly when analyzing biological samples, environmental samples, pharmaceutical formulations, and other complex matrices containing particulates or strongly retained compounds.
