Prep Guard Column Cartridge, RP C4, 5um, 100A. 21.2mm ID x 10mm Length. Cogent Brand. 1 EA. Special Order Item.

Additional Information:

Cogent RP C4™ Prep 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 C4™ stationary phase used in Cogent preparative columns, these cartridges help maintain method consistency while extending the service life of preparative columns. The stationary phase consists of a four-carbon butyl ligand bonded to ultra-high purity silica and is fully double end capped for reproducible reversed-phase performance.

68504-P21-PG1 is a preparative guard column cartridge packed with 5 µm RP C4™ particles featuring a 100 Å pore size in a 21.2 mm ID x 10 mm format. Designed specifically to protect Cogent RP C4™ preparative columns, the cartridge captures particulates and contaminants before they reach the analytical bed. Constructed from a stainless steel tube with stainless steel frits, it provides durability and reliable performance in demanding preparative HPLC applications.

This guard column cartridge is particularly useful for preparative purification of hydrophobic and neutral compounds in pharmaceutical, chemical, and research laboratories. Routine replacement of guard cartridges helps maintain preparative column performance, preserve chromatographic efficiency, and reduce overall operating costs associated with preparative separations.
