New Guard for Better Performance, Longer Prep Column Life

Isolation Technologies announces the release of Iso-Prep Guard, a guard cartridge system designed to protect valuable prep columns. Iso-Prep Guard offers superior column protection for adsorptive samples and a proven sample distribution mechanism via a precision machined holder. Its short 10mm length yields low pressure drop at flow rates in excess of 50ml/min. It is ideal for protecting prep columns from 20-50mm inner diameter with no degradation of peak shape or plate count.

"Iso-Prep Guard protects columns in two ways," says Geoff Todosiev, Vice President of Business Development for Isolation Technologies. "First, it acts as a filter, trapping particles in their frits. Second, when the guard column is packed with the same material as the prep column, it removes compounds that irreversibly adsorb to the packing material."

A simple packing technique adds to the time-saving effectiveness of Iso-Prep Guard Cartridge. The 10 x 21.2mm (length x diameter) Iso-Prep Guard Cartridge system is now available from Isolation Technologies.
