IC Guard Columns and Cartridges
Thermo Scientific IonPac Guard Column AG7 4x50mm
An ion exchange guard column for ion chromatography with 4mm diameter and 50mm length containing inert polyvinyl polymer functionalized with quaternary ammonium groups to protect the analytical column from contamination and degradation by adsorbing anionic contaminants and strongly retained sample components, improving analytical column lifespan and performance when used inline before the column.

NC0667069 AG11-HC 4 UM 2X50 MM GUARD
Metrohm USA METROHM CAUTION GUARD COLUMN
The Metrosep C 4 Guard/4.0 contains the C-4 column material and is used to protect all Metrosep cation columns that have a substrate based on silica gel. Particles and contaminations are reliably retained, allowing the lifetime of the analytical separation column to be prolonged considerably. The economical price is an additional plus. The Metrosep C 4 Guard/4.0 also functions according to the "On Column Guard System" and is screwed directly onto the separation column with nearly no dead volume.
