Catalog Number - 68524-P30-PG1

Cogent RP Phenyl™ Preparative Guard Column Cartridges are designed to protect preparative HPLC columns from particulates, strongly retained compounds, and other contaminants that can reduce column performance and shorten column service life. Packed with the same stationary phase as the analytical column, these cartridges help maintain chromatographic performance while reducing operating costs associated with replacing larger preparative columns.

Catalog Number 68524-P30-PG1 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 cartridge is packed in a stainless steel tube with stainless steel frits and is designed to protect RP Phenyl™ preparative columns from particulate contamination and strongly retained sample components.

The 30 mm ID x 10 mm format is specifically designed for use with 30 mm ID RP Phenyl™ preparative HPLC columns. Routine guard cartridge replacement helps maintain separation efficiency, reduce downtime, and extend preparative column service life.
