A new cartridge system replaces traditional guard columns, offering a more convenient and cost-effective system for protecting expensive GPC columns from the damaging effects of contaminants and microparticulates. The SecurityGuard family of products includes a cartridge-based system that protects any non-aqueous gel permeation chromatography (GPC) column. The special cartridge design enables the user to visually inspect the surface of the column’s packing material at any time and monitor contaminant build-up. The visual inspection allows for cartridge changes at the right time to maintain optimal column protection and performance.
The system is compatible with any manufacturer’s GPC column of any particle or pore size. It is easy to use and connects directly into the column without the use of additional fittings that can decrease column performance. The cartridges can even be double-stacked for added protection. The new cartridges are offered in economical three-packs. Phenomenex
