Guard Column Cartridges, RP C12, 10um, 100A. 4.0mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent RP C12 Guard Column Cartridges are packed with the same unique stationary phase used in Cogent RP C12 analytical columns. The adamantane-based bonded phase features a rigid, diamond-like carbon structure attached to high-purity silica with complete double endcapping. This distinctive chemistry provides excellent performance for complex mixtures, rapid equilibration between runs, and compatibility with 100% aqueous mobile phases while helping maintain the selectivity characteristics of RP C12 analytical columns.
68012-PG2 contains five guard column cartridges packed with 10 µm RP C12 material featuring a 100 Å pore size in 4.0 mm ID x 10 mm length hardware. Designed for use with 3.0 mm, 4.0 mm, and 4.6 mm ID RP C12 analytical columns, these guard cartridges help intercept particulates, strongly retained contaminants, and sample matrix components before they reach the analytical column. The matching stationary phase chemistry helps preserve chromatographic selectivity while protecting valuable analytical columns from contamination and premature fouling.
Used in analytical HPLC, pharmaceutical analysis, quality control testing, method development, environmental testing, and high-throughput screening applications, these guard cartridges help preserve column efficiency, improve reproducibility, and reduce replacement costs. The stainless steel cartridge construction incorporates stainless steel frits pressed into durable PEEK frit caps for reliable performance across a wide range of reversed-phase HPLC methods.
