Guard Columns

Catalog-listed Benson guard columns for matching ionic forms and resin cross-link densities.

Guard columns are used upstream of an analytical column to intercept sample particulates and strongly retained contaminants. Match the guard chemistry and ionic form to the analytical column and verify compatibility with the intended method. Replacement frequency depends on sample cleanliness, preparation and pressure behavior.
