Semi Prep Guard Column Cartridge, RP C4, 5um, 100A. 10mm ID x 10mm Length. Cogent Brand. 5/PK. Special Order Item.
Additional Information:
Cogent RP C4™ Semi-Prep Guard Column Cartridges are designed to protect valuable semi-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 semi-preparative columns, these guard cartridges help maintain method consistency while extending column service life. 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-SP-PG1 is a semi-preparative guard column cartridge set packed with 5 µm RP C4™ particles featuring a 100 Å pore size in a 10 mm ID x 10 mm format. Designed specifically to protect RP C4™ semi-preparative columns, these cartridges capture particulates and contaminants before they reach the analytical bed. Constructed from stainless steel tubing with stainless steel frits, they provide durability and reliable performance in demanding purification applications. This package contains five guard column cartridges.
Routine replacement of guard cartridges helps maintain column efficiency, preserve chromatographic performance, and reduce the cost of semi-preparative column replacement. These cartridges are ideal for purification of hydrophobic and neutral compounds in pharmaceutical, chemical, and research laboratories.
