Catalog Number - 68512-P30-PG1

Cogent RP C12™ Preparative Guard Column Cartridges are designed to protect valuable preparative HPLC columns from particulates, strongly retained compounds, and sample contaminants that can reduce column performance and shorten column life. Packed with the same RP C12™ stationary phase used in Cogent preparative columns, these guard cartridges help maintain chromatographic consistency while extending column service life. The stationary phase is manufactured using a rigid adamantane-shaped carbon silane ligand bonded to ultra-high purity silica and fully double end capped to provide reproducible reversed-phase performance and rapid equilibration.

68512-P30-PG1 is a preparative guard column cartridge packed with 5 µm RP C12™ particles featuring a 100 Å pore size in a 30 mm ID x 10 mm format. Designed specifically to protect RP C12™ preparative columns, this cartridge captures particulates and contaminants before they reach the primary column bed. The unique RP C12™ chemistry provides selectivity between traditional C8 and C18 phases while maintaining compatibility with highly aqueous mobile phases, including 100% water. Constructed from stainless steel tubing with stainless steel frits, it provides durability and reliable performance in preparative purification workflows.

Routine replacement of guard cartridges helps maintain column efficiency, preserve chromatographic performance, and reduce the cost of replacing larger preparative columns. These cartridges are particularly beneficial for compound isolation, fraction collection, process development, and analytical-to-preparative method scale-up where protecting the preparative column is essential.
