Catalog Number - 68524-PG2

Cogent RP Phenyl™ Guard Column Cartridges are designed to protect analytical HPLC columns from particulates, strongly retained compounds, and other contaminants that can reduce column performance and shorten column lifetime. Packed with the same stationary phase as the analytical column, these guard cartridges help maintain chromatographic performance while reducing the cost and frequency of analytical column replacement.

68524-PG2 is packed with 5 µm RP Phenyl™ stationary phase featuring a 100Å pore size. Manufactured using ultra-high purity silica with a traditional three-carbon linker and terminal Phenyl functionality, this phase is fully double end-capped to minimize secondary interactions and provide highly reproducible chromatographic performance. The cartridges are housed in stainless steel tubes and utilize stainless steel frits secured within durable PEEK frit caps for reliable operation and long service life.

The 4.0 mm ID x 10 mm format is designed to protect 3.0 mm, 4.0 mm, and 4.6 mm ID RP Phenyl™ analytical HPLC columns from particulate contamination and strongly retained sample components. Routine guard cartridge replacement helps maintain column efficiency, minimize downtime, and extend analytical column service life.
